Abstract

The Comprehensive Learner Record (CLR) Standard has been designed to create, transmit, and render an individual's set of achievements, as issued by multiple learning providers, in a machine-readable format that can be curated into verifiable digital records of achievement.

Overview

Audiences

The target readers for this document are:

• Business Leaders - the people who are responsible for identifying the business case for using verifiable digital credentials and badges
• Solution Architects - the people who are responsible for the definition and design of systems, applications, and tools that are to be used to issue, exchange, and verify digital credentials and badges
• Product Developers - the people who are adding functionality to issue, exchange, and verify digital credentials

Document Set

The CLR Standard (Comprehensive Learner Record Standard) has several related documents and artifacts shown below. Together they make up the specification.

• Comprehensive Learner Record Standard v2.0 - The main CLR Standard 2.0 specification document.
• Open Badges Implementation Guide v3.0 - Provides information to lead you to successful implementation and certification of the Comprehensive Learner Record 2.0 specification.
• Comprehensive Learner Record Standard Conformance and Certification Guide v2.0 - Specifies the conformance tests and certification requirements for this standard.

OpenAPI 3.0 Files

The Open API Specification (OAS) defines a standard, programming language-agnostic interface description for HTTP APIs, which allows both humans and computers to discover and understand the capabilities of a service without requiring access to source code, additional documentation, or inspection of network traffic. When properly defined via OpenAPI, a consumer can understand and interact with the remote service with a minimal amount of implementation logic. Similar to what interface descriptions have done for lower-level programming, the OpenAPI Specification removes guesswork in calling a service.

• YAML OpenAPI File

JSON-LD Context File

When two people communicate with one another, the conversation takes place in a shared environment, typically called "the context of the conversation". This shared context allows the individuals to use shortcut terms, like the first name of a mutual friend, to communicate more quickly but without losing accuracy. A context in JSON-LD works in the same way. It allows two applications to use shortcut terms to communicate with one another more efficiently, but without losing accuracy.

Simply speaking, a context is used to map terms to IRIs. Terms are case sensitive and any valid string that is not a reserved JSON-LD keyword can be used as a term.

-- JSON-LD 1.1

The context file is available at: https://purl.imsglobal.org/spec/clr/v2p0/context-2.0.1.json.

JSON Schema

All JSON Schema can be found in JSON Schema. JSON Schema files for credentials and API schema verification are available online:

• ClrCredential JSON schema
• AchievementCredential JSON schema
• EndorsementCredential JSON schema
• GetClrCredentialsResponse JSON schema
• Profile JSON schema
• Imsx_StatusInfo JSON schema

Note: The above schemas are based on the Verifiable Credentials Data Model v2.0. An issuer may also issue credentials following the previous version Verifiable Credentials Data Model v2.0. JSON schema matching that version are:

• ClrCredential JSON schema (Verifiable Credential Data Model v1.1 compatible)
• EndorsementCredential JSON schema (Verifiable Credential Data Model v1.1 compatible)

Verifiers may accept credentials following either schema using Schemas for verification support.

Conformance Statements

As well as sections marked as non-normative, all authoring guidelines, diagrams, examples, and notes in this specification are non-normative. Everything else in this specification is normative.

The key words MAY, MUST, MUST NOT, NOT RECOMMENDED, NOT REQUIRED, OPTIONAL, RECOMMENDED, REQUIRED, SHALL, SHALL NOT, SHOULD, and SHOULD NOT in this document are to be interpreted as described in Key words for use in RFCs to Indicate Requirement Levels.

An implementation of this specification that fails to implement a MUST/REQUIRED/SHALL requirement or fails to abide by a MUST NOT/SHALL NOT prohibition is considered nonconformant. SHOULD/SHOULD NOT/RECOMMENDED statements constitute a best practice. Ignoring a best practice does not violate conformance but a decision to disregard such guidance should be carefully considered. MAY/OPTIONAL statements indicate that implementers are entirely free to choose whether or not to implement the option.

The Conformance and Certification Guide for this specification may introduce greater normative constraints than those defined here for specific service or implementation categories.

Terminology

Achievement Type

A vocabulary which describes the type of achievement.

Alignment

An alignment is a reference to an achievement definition, whether referenced in a resource outside the package or contained within the package.

Association

An association is the relationship between one assertion in a CLR has with another assertion in that CLR.

Claim

A statement about the Credential Subject. A claim may include associated evidence, results, or other metadata regarding a specific achievement, skill or assertion.

Client

In a REST API, the client is the actor that initiates the DELETE, GET, or POST request. Also called a Consumer in the IMS Global Security Framework v1.1.

Comprehensive Learner Record (CLR)

Set of assertions that can be packaged as a verifiable credential.

Credential

A set of one or more claims made by an issuer. A verifiable credential is a tamper-evident credential that has authorship that can be cryptographically verified. Verifiable credentials can be used to build verifiable presentations, which can also be cryptographically verified. Verifiable Credentials Data Model v2.0

Credential Subject

Describes the claims being made by the Verifiable Credential. In the context of Open Badges and CLR is typically an individual but in the case of Open Badges, may be another entity type such as a course, book, or organization. Learners, Organizations and other entities can be explicit subclasses of Credential Subjects for purposes of business rules. Verifiable Credentials Data Model v2.0

Decentralized Identifiers

A type of identifier for people, organizations and any other entity, where each identifier is controlled independently of centralized registries. Decentralized Identifiers (DIDs) v1.0 Use Cases and Requirements for Decentralized Identifiers

Digital Credential Achievement (DC Achievement)

This is the content description of a credential that an assertion references. It contains metadata such as the name of the achievement, description, alignment of skills, etc. An Open Badge asserts a single achievement. A CLR asserts a collection of assertions, each of which asserts a single achievement.

Digital Credential Assertion (DC Assertion)

The core of both Open Badges and CLR is the assertion about achievement(s). DC Assertion properties are specific to one learner's achievement and specify metadata such as issuer, date of achievement, expiration data, as well as results and evidence that support the assertion. A Verifiable Credential more broadly asserts a claim about a Credential Subject which can be applied to education and occupational achievements.

Evidence

Information supporting a claim such as a URL to an artifact produced by the Learner.

Issuer

A role an entity can perform by asserting claims about one or more subjects, creating a verifiable credential from these claims, and transmitting the verifiable credential.

Learner

The person who is the subject of the CLR and assertions contained in a CLR.

Open Badge

A single assertion of an achievement that is packaged as a verifiable credential.

Organization

An organized group of one or more people with a particular purpose. Common Education Data Standards (CEDS) Version 7 Data Model Guide

Person

A human being, alive or deceased, as recognized by each jurisdiction’s legal definitions. Common Education Data Standards (CEDS) Version 7 Data Model Guide

Presentation

Data derived from one or more verifiable credentials, issued by one or more issuers, that is shared with a specific verifier. A verifiable presentation is a tamper-evident presentation encoded in such a way that authorship of the data can be trusted after a process of cryptographic verification. Verifiable Credentials Data Model v2.0

Publisher

The organization or entity issuing the CLR (typically the educational institution or a 3rd-party agent). The publisher is either the issuer or has a trusted relationship with the issuer of all the assertions in the CLR.

Relying Third-Party

Also referred to as the "verifier" of a VC. This entity requests, verifies, and may consume data being presented.

REST API

A style of web API (Application Programming Interface) loosely based on HTTP methods (DELETE, GET, POST, and PUT) to access resources (e.g. CLRs) via a URL.

Result

Describes a possible achievement result. A result may contain the rubric level that was achieved.

Result Description

Describes a possible achievement result. A result description may contain a rubric.

Rich Skill Descriptor (RSD)

A machine readable reference to a description of a skill located at a unique URL. Rich Skill Descriptors

Role

People have roles in organizations for specific periods of time. Roles are a time aware association between a person and an organization. Common Education Data Standards (CEDS) Version 7 Data Model Guide

Rubric

Defines levels associated with the achievement definition (e.g. "approaches", "meets", and "exceeds").

Server

In a REST API, the server is the actor that responds to a DELETE, GET, or POST request. Also called a Platform in the IMS Global Security Framework v1.1.

Skill Assertion

An assertion that contains a "skill result."

Validation

The process of assuring the verifiable credential or verifiable presentation meets the needs of the verifier and other dependent stakeholders. Validating verifiable credentials or verifiable presentations is outside the scope of this specification.

Verifiable Credential (VC)

A tamper-evident credential whose issuer can be cryptographically verified. See Verifiable Credentials Data Model v2.0.

Verifiable Presentation (VP)

A tamper-evident presentation of one or more Verifiable Credentials of which cryptographic verification can be used to determine the trustworthiness of the authorship of the data. Verifiable Credentials Data Model v2.0.

Verification

The evaluation of whether a verifiable credential or verifiable presentation is an authentic and timely statement of the issuer or presenter, respectively. This includes checking that: the credential (or presentation) conforms to the specification; the proof method is satisfied; and, if present, the status check succeeds.

Verifier

The entity that receives a verifiable credential or verifiable presentation and verifies the credential or presentation has not been tampered with.

Conceptual Model

This conceptual model describes CLR concepts and the relationship between those concepts. The data model in appendix shared-credential-data-models below is the normative reference for the classes and properties that are used to implement the concepts.

The conceptual model is targeted for all Audiences, while the data model is targeted for Solution Architects and Product Developers.

In the diagram below, the concepts are shown in gray boxes (e.g. Associations). Please see Terminology for definitions of the concepts.

Starting with this version of the CLR Standard, a CLR is also a Verifiable Credential (VC) as defined by the Verifiable Credentials Data Model v2.0 specification. The diagram includes labels that show the relationships between VC terminology and CLR terminology (e.g. Publisher is identified by the VC "issuer").

• I, Publisher assert a Claim about this Credential Subject
  • The claim provides the identity of the publisher, issuance date, and instructions on how to cryptographically prove the publisher identity and that the assertion and claim contents have not been tampered with since issuance.
    • The claim must describe a single credential subject which identifies the recipient of the CLR as the learner.
    • The claim must also contain a packaged set of assertions where each assertion is a DC Assertion with a definition shared by the Open Badges Specification v3.0 and Comprehensive Learner Record Standard v2.0 standards. The issuer of each assertion may or may not be the same entity as the publisher. The recipient of each assertion must be the Learner even if the issuer uses a different identification for the learner. The publisher claims that this packaged set of assertions represents the publisher’s complete CLR for the learner at the time of issuance.
    • The claim may also contain a packaged set of DC Achievements which the publisher claims to represent a complete set of achievements that may be asserted by issuers about the learner at some time in the future.
    • The claim may also contain Associations between assertions in the CLR.

Recent graduate wants to hold a copy of their own official transcript

Categories: Higher Ed, K12

Samuel is a recent graduate of Atlas University. They majored in Mechanical Engineering and received a BSE Degree. Samuel requests an official diploma and transcript issued by Atlas University to store in their VC-compatible Wallet. Samuel requests the transcript from the Registrar's Office. The Registrar issues the transcript as a CLR Verifiable Credential (CLR VC) and notifies Samuel to accept the CLR into their wallet. The CLR VC includes several Assertions including the BSE Degree and Course completions.

Goal of the Primary Actor: Samuel's goal is to hold their BSE Degree and transcript to share directly with employers or other institutions that require and need to verify their degree and/or transcript.

Preconditions for this Use Case:

• Altas University has implemented the CLR VC specification and been authorized to publish credentials.
• Samuel has created a wallet supported by the CLR VC publisher and registered it with Altas (email address or other identifier).

Flow of Events:

1. Samuel requests the credentials be issued by Atlas University.
2. Atlas issues the credentials to a known wallet user Samuel has registered.
3. Samuel receives a notification that a credential has been issued.
4. Samuel logs into his wallet and is prompted to accept the credential.

Post-Conditions/Success Criteria:

• Samuel holds his credentials on one or more wallets (web app, mobile app) and when is asked to provide any of his credentials, they are able to securely share the credential(s) through an email invitation or a direct transfer of the CLR to the validators (institution or employer) system by scanning a QR code provided by the validator and approving the credential be sent.
• The credential received by the validator is validated using W3C VC and the credential(s) are accepted.

Points of Failure:

• CLR Publishing Engine.
• Wallet availability.

Variations:

• Samuel is a recent graduate of a high school and received a diploma and transcript.
• The official transcript Includes the BSE Degree and Course completions with evidence demonstrating their knowledge of concepts, and co-curricular Assertion VCs issued by Atlas University partners.

The official transcript contains pointer data toward course-related metadata such as the syllabus.

Job applicant provides proof of degree and transcript to potential employer

Categories: Higher Ed, Employment

Samuel wants to apply for a job opening at ACME Company. The job description requires proof of a degree in Mechanical Engineering and prefers that candidates provide a complete transcript. ACME Company will accept a Verifiable Presentation as evidence to accompany the job application. Samuel holds a CLR that bundles together their BSE Degree assertion and the assertions recognizing courses completed with relevant evidence. Using their wallet, Samuel creates a Verifiable Presentation that includes the Transcript CLR and attaches the VP to their job application. Horace, in HR at ACME Company uses the VP proof to verify that the VP was not corrupted, and the VC proofs to verify that the data issued by Atlas University was not corrupted as a complete transcript of Samuel's achievements at the school.

Goal of the Primary Actor: Samuel wants to prove that they have met the degree requirements for a position.

Actors:

• Samuel, a college graduate and job applicant.
• Horace, HR staff at ACME Company.

Preconditions for this Use Case:

• Samuel holds a CLR including their degree assertion and the full transcript of assertions they received from their university for course completions, competencies, and extracurriculars.
• Samuel has a VC wallet capable of presenting the CLR VC as a Verifiable Presentation. ACME Company has verifier software that can verify the VP and unpack the CLR schema and perform additional verification of each assertion it contains. This software, or its human operator, can identify the degree assertion from among the set, verify that it meets their needs, and can view and understand the other assertions included in the CLR.

Flow of Events:

1. Samuel receives a request from ACME Company to present their credentials.
2. Samuel selects the CLR credential as responsive to the request.
3. The wallet uses Samuel's cryptographic key information to sign a VP containing the CLR VC.
4. The VP is transmitted to ACME Company in response to the request.
5. ACME's verifier software verifies the authenticity of the CLR VC, and further unpacks the individual assertions, verifying each.
6. The software presents the list of assertion credentials to Horace to review.
7. Horace confirms that the issuer is as expected, all relevant credentials are valid, and that the degree assertion is present and meets expectations. He reviews the list of courses, competencies, and extracurriculars and finds that Samuel is a well-experienced candidate.

Post-Conditions/Success Criteria:

• The CLR is successfully transferred to the verifier, who has verified not only the validity of the outer layer, but also of each assertion contained within.

Points of Failure:

• ACME's verifier and Samuel's wallet must be able to negotiate a credential request (or through some other mechanism determine how the VP should be delivered to verifier).
• Samuel must be able to select the CLR credential in response to the credential request.
• ACME's verifier software must be able to verify the signatures created through the mechanism chosen for the VP and the VC it contains.
• ACME's verifier software must be CLR-aware, capable of unpacking and verifying the individual assertions within the CLR schema.
• ACME must be able to verify that the issuer (university) is authentic.

Variations:

• Samuel initiates the flow by generating a VP from their wallet and transmitting it to the verifier (either through an upload form, or by email).

Job applicant provides proof of degree and specific courses/engagements from the CLR

Categories: Higher Ed, Employment

Monique wishes to apply for a job opening at CHEM pharmaceutical Company. The job description requires proof of a degree in Chemistry and successful completion of Organic Chemistry class. The student possesses their institutionally issued CLR, but wishes to submit only the Degree and the Organic Chemistry courses to the CHEM company. Using their wallet, Monique creates a CLR Verifiable Presentation that pulls the Attested Degree and Courses from their CLR transcript. Harry, in HR at CHEM Company uses the VP proof to verify that the VP was not corrupted, and the VC proofs to verify that the data issued by the institution was not corrupted. There is an indicator on the CLR to let Harry know 1) the publisher was the student, 2) the record asserted was not the entire institutional transcript, and 3) the authority behind the degree is the institution, but the authority behind the assessment in the course in the College of Arts and Sciences.

Goal of the Primary Actor: Monique wishes to apply for a job opening at CHEM pharmaceutical Company.

Actors:

• Monique, Job applicant.
• Harry, HR professional.

Preconditions for this Use Case:

• Student possesses their institutionally issued CLR (Complete Transcript).
• CLR includes the Attested Degree and Courses.
• CLR indicates to the verifier (employer) that the publisher was the student, the record asserted was not the entire institutional transcript, and that the authority behind the degree is the institution, but the authority behind the assessment in the course in the College of Arts and Sciences.
• Student has a digital wallet or other method of curation and sharing.
• Student can submit a subset of their credentials (only proof of Degree and completion of Organic Chemistry courses to the CHEM company).

Flow of Events:

1. Monique applies using her institutionally issued CLR and a digital wallet to curate and share only the two required verifiable credentials in a VP.
2. HR verifies the VP proof to verify that the VP was not corrupted, and the VC proofs to verify that the data issued by the institution was not corrupted and see that the CLR's publisher was the student (self asserted) and the record being asserted is not the entire institutional transcript but proof of a degree and of a single course completion.

Post-Conditions/Success Criteria:

• HR verifies the VP proof to verify that the VP was not corrupted, and the VC proofs to verify that the data issued by the institution was not corrupted and see that the CLR's publisher was the student (self asserted) and the record being asserted is not the entire institutional transcript but proof of a degree and of a single course completion.
• HR sees that the authority behind the degree is the institution and the authority behind the assessment in the course in the College of Arts and Sciences.

Higher Ed Competency-Based Education

Categories: Higher Ed, Training Providers

As a learner, I would like recognition and verification of all the credentials I acquired within the certificate, micro-credential, or degree program I attended, covering both academic and experiential learning activities I was involved in. The credentials would include the set of skills I acquired related to the degree or the certificate program I completed, the learning experiences I completed, along with the assessments carried out during my learning. The work I created for those assessments, and results of the assessments with scale and success level information should be included as evidence of my learning and skills. These achievements should be transferable so that I can continue to add upon these in my lifelong learning and be accepted by employers as proof of employability.

Goal of the Primary Actor: Learner wants to have skills-enhanced credentials that specify assessment approaches - from their academic as well as extracurricular/experiential learning represented in their CLR so they can best represent their abilities.

Actors:

• Learner.
• Issuer.
• Employer.
• Training Provider.

Preconditions for this Use Case:

• Issuer is using digital credentials that are at least OB2 compliant and making use of Earning Criteria and Alignment properties (BadgeClass/Achievement) and Evidence class and other properties that individually cover assessment work product, including experiential learning work products versus typical objective/performance assessment result. Or Issuer is on a path to do so.

Flow of Events:

1. Issuer designs, develops and launches degree and non-degree offerings based on market relevance and skills most sought by employers.
2. Issuer creates and issues skills-aligned digital badges (or OB assertions within CLR assertion) for targeted achievements within the aforementioned degree and non-degree offerings.
3. Learner receives and can share CLR, which includes all earned digital credentials and a full listing of market relevant skills for each.

Post-Conditions/Success Criteria:

• Learner has a full record of their earned credentials with full listings of relevant skills, assessment methods, and evidence/work product (if relevant) underlying each. Potential employers and partner academic institutions can receive this same information in a CLR (web page or document) or as structured data that their internal systems can consume to support hiring efforts or admissions/articulation, respectively.

Points of Failure:

• Less related to technical solution, but robust coverage of assessment methods and evidence/work product per earned credential is a large commitment to Issuers operating at scale. Other failure point - if work product URL is tied to to 3rd party tool (like online portfolio), that link must persist as a dependency. Use case also calls for Issuer verification of experiential learning achievements, which can be logistically challenging when operating at scale.

Issuer Asserting All Student Achievements Comprehensively as a CLR

Categories: Higher Ed, K12

As an Issuer, I need to make a single, bulk CLR assertion for a student's full academic record with my institution. This may include degree completion and any underlying or related credentials such as courses, certificates, competencies, etc.

Goal of the Primary Actor: Assert/confer a full record for a student who has completed their program of study. Full manifest, similar to final academic transcript but also including complementary achievements that don't appear on the transcript, such as badges, competencies and skills.

Actors:

• Issuing organizations.

Preconditions for this Use Case:

• Learner holds a wallet that can accept CLR credentials.
• Institution has implemented the CLR VC specification to publish credentials.

Flow of Events:

1. Student completes program of study.
2. Issuer assets all academic achievements for this learner via a comprehensive CLR assertion.
3. Consuming system, such as LER, represents all achievements in comprehensive assertion in student's learner record.
4. Student makes achievements in record discoverable/shares.
5. Hiring managers with relevant needs discover student based on their comprehensive achievement data.

Post-Conditions/Success Criteria:

• All achievements in CLR assertion processed, ingested, and presentable in LER interfaces.

Points of Failure:

• Duplicate assertions of individual achievements, revocation.

Issuer Asserting Partial Transcript at Intermediate Points in Learning Journey

Categories: Higher Ed, K12

As an Issuer that operates under a more traditional semester or term model, I need to make batch-level CLR assertions per student at the end of each semester/term to augment their record with their semester/term achievements. I will make similar assertions at the end of each semester/term until the student completes their program of study.

Goal of the Primary Actor: Update Learning and Employment Record in batches tied to my semester/term schedule.

Actors:

• Issuing organizations.

Preconditions for this Use Case:

• Learner holds a wallet that can accept CLR credentials.
• Institution has implemented the CLR VC specification to publish credentials.

Flow of Events:

1. Learner is enrolled in multiple courses and earns achievements within them (i.e., competency-level) and at their completion.
2. Issuer makes CLR assertion at the end of each semester/term for each learner - can consist of multiple levels of achievement including course completion and related/child achievements like certificates earned, competencies mastered.
3. Learner wallet system for a student receives semester/term assertion and displays achievements to the student.

Post-Conditions/Success Criteria:

• All achievements in CLR assertion processed, ingested, and presentable in LER interfaces.
• Subsequent assertions (for later terms) augment the record accordingly.

Points of Failure:

• Duplicate assertions of individual achievements, revocation.

Issuer Asserting Student Up to Date Partial Transcript of Achievements as CLR on Request

Categories: Higher Ed, K12

As an Issuer that uses a non-standard enrollment or term approach, I need to assert student achievements individually to augment their record with timely achievement/credential data as they occur, without limiting myself to using other data models/specifications or requiring my school to engineer for multiple data models. I also prefer the robustness of the CLR data model to other alternatives.

Goal of the Primary Actor: Assert achievements individually using CLR data specification to incrementally update student wallets/LERs with their achievements and credentials as soon as they are earned or on student request. Students will not have to wait until the end of each semester or program completion for their CLR-based achievements to be represented and leverage them in pursuing career goals incrementally.

Example: a student in our Cybersecurity Bachelor's program may earn CISSP certification at program midpoint and be able to gain entry-level employment in the cyber field long before completing their full degree. Incremental assertion of achievements and credentials can help enable this.

Actors:

• Issuing organizations.

Preconditions for this Use Case:

• Learner holds a wallet that can accept CLR credentials.
• Institution has implemented the CLR VC specification to publish credentials.

Flow of Events:

1. Learner is enrolled in multiple courses and earns achievements within them (i.e., competency-level) and at their completion.
2. Issuer makes CLR assertion for each discrete achievement as they occur or as the student requests them.
3. Learner wallet system for a student receives semester/term assertion and displays achievements to the student.

Post-Conditions/Success Criteria:

• Individual achievement in CLR assertion processed, ingested, and presentable into learner wallet system. Subsequent assertions for later achievements augment the record accordingly.

Points of Failure:

• Duplicate assertions of individual achievements, revocation.

ClrCredentials can be exchanged as documents as defined in this section, or using the CLR Standard API. Documents can be exchanged as a text file, as a web resource, or embedded in an image. The contents of a CLR document MUST meet the following criteria:

• The contents of the CLR document MUST represent exactly one ClrCredential
• The contents MUST be serialized as JSON and JSON-LD (see Serialization)
• JSON exchanged between systems that are not part of a closed ecosystem MUST be encoded using UTF-8 UTF-8, a transformation format of ISO 10646.

File Format

If the credential is signed using the JSON Web Token Proof Format (VC-JWT) the contents of the file MUST be the Compact JWS string formed as a result of signing the ClrCredential with VC-JWT. The file extension SHOULD be ".jws" or ".jwt".

If an embedded proof method is used instead, the contents of the file MUST be the JSON representation of the ClrCredential. The file extension SHOULD be ".json".

Web Resource

If the credential is signed using the JSON Web Token Proof Format (VC-JWT) the contents of the response MUST be the Compact JWS string formed as a result of signing the ClrCredential with VC-JWT. The Content-Type SHOULD be text/plain.

If an embedded proof method is used instead, the contents of the response MUST be the JSON representation of the ClrCredential. The Content-Type SHOULD be application/vc+ld+json, although generic representations such application/ld+json or application/json are also allowed.

Image Format

Comprehensive Learner Records (CLRs) may be exchanged as image files with CLRs encoded within. This allows CLRs to be portable wherever image files may be stored or displayed.

"Baking" is the process of taking a ClrCredential and embedding it into the image, so that when a user displays the image on a page, software that is CLR-aware can automatically extract that ClrCredential data and perform the checks necessary to see if a person legitimately earned the achievements within the CLR. The image must be in either Portable Network Graphics (PNG) Specification (Third Edition) or Scalable Vector Graphics (SVG) 1.0 Specification format in order to support baking.

PNGs

Baking

An iTXt chunk should be inserted into the PNG with keyword clrcredential.

If the credential is signed using the JSON Web Token Proof Format (VC-JWT) the text value of the chunk MUST be the Compact JWS string formed as a result of signing the ClrCredential with VC-JWT. Compression MUST NOT be used.

Example: An example of creating a chunk with VC-JWT proof (assuming an iTXt constructor)

  var chunk = new iTXt({
    keyword: 'clrcredential',
    compression: 0,
    compressionMethod: 0,
    languageTag: '',
    translatedKeyword: '',
    text: 'header.payload.signature'
  });

If an embedded proof method is used instead, the text value of the chunk MUST be the JSON representation of the ClrCredential. Compression MUST NOT be used.

Example: An example of creating a chunk with embedded proof (assuming an iTXt constructor)

  var chunk = new iTXt({
    keyword: 'clrcredential',
    compression: 0,
    compressionMethod: 0,
    languageTag: '',
    translatedKeyword: '',
    text: '{
            "@context": [
              "https://www.w3.org/ns/credentials/v2",
              "https://purl.imsglobal.org/spec/clr/v2p0/context-2.0.1.json",
              "https://purl.imsglobal.org/spec/ob/v3p0/context-3.0.3.json",
              "https://purl.imsglobal.org/spec/ob/v3p0/extensions.json"
            ],
            "id": "http://example.edu/credentials/3732",
            "type": ["VerifiableCredential", "ClrCredential"],
            "issuer": {
              "id": "https://example.edu/issuers/565049",
              "type": "Profile",
              "name": "Example University"
            },
            "validFrom": "2010-01-01T00:00:00Z",
            "credentialSubject": {
              "id": "did:example:ebfeb1f712ebc6f1c276e12ec21"
            },
            "proof": { }
          }'
  });

An iTXt chunk with the keyword clrcredential MUST NOT appear in a PNG more than once. When baking an image that already contains credential data, the implementor may choose whether to pass the user an error or overwrite the existing chunk.

Extracting

Parse the PNG datastream until the first iTXt chunk is found with the keyword clrcredential. The rest of the stream can be safely discarded. The text portion of the iTXt chunck will either be the JSON representation of a ClrCredential or the Compact JWS string that was the result of signing the ClrCredential with JSON Web Token Proof Format.

SVG

Baking

First, add an xmlns:clr attribute to the <svg> tag with the value "https://purl.imsglobal.org/clr/v2p0". Directly after the <svg> tag, add an <clr:credential> tag.

If the credential is signed using the JSON Web Token Proof Format (VC-JWT) add a verify attribute to the <clr:credential> tag. The value of verify attribute MUST be the Compact JWS string formed as a result of signing the ClrCredential with VC-JWT.

Example: An example of a well baked SVG with VC-JWT proof

  <?xml version="1.0" encoding="UTF-8"?>
  <svg xmlns="http://www.w3.org/2000/svg"
    xmlns:clr="https://purl.imsglobal.org/clr/v2p0"
    viewBox="0 0 512 512">
    <clr:credential verify="header.payload.signature"></clr:credential>

    <!-- rest-of-image -->
  </svg>

If an embedded proof method is used instead, omit the verify attribute, and the JSON representation of the ClrCredential MUST go into the body of the tag, wrapped in <![CDATA[...]]>.

Example: An example of a well baked SVG with embedded proof

  <?xml version="1.0" encoding="UTF-8"?>
  <svg xmlns="http://www.w3.org/2000/svg"
    xmlns:clr="https://purl.imsglobal.org/clr/v2p0"

          "proof": { }
        }
      ]]>
    </clr:credential>

    <!-- rest-of-image -->
  </svg>

There MUST be only one clr:credential tag in an SVG. When baking an image that already contains ClrCredential data, the implementor may choose whether to pass the user an error or overwrite the existing tag.

Extracting

Parse the SVG until you reach the first clr:credential tag. The rest of the SVG data can safely be discarded.

CLR Standard API

CLRs can be exchanged using the API (application programming interface) defined here, or as documents.

This specification defines a RESTful API protocol to be implemented by applications serving in the roles of Client and Resource Server. The API uses OAuth 2.0 for authentication and granular resource-based permission scopes. Please see the Comprehensive Learner Record Standard Conformance and Certification Guide v2.0 for a list of which endpoints must be implemented for certification.

The API defined here is intended for Clients and Servers that give individual users control over access to their resources. While system-to-system bulk transfers using OAuth 2.0 Client-Credentials Grant are expected to occur, it is out of scope for this version of the specification to define. Future versions of this specification may add explicit support for OAuth 2.0 Client-Credentials Grant.

In addition to the documentation in this section, there are OpenAPI files for the CLR Standard API in both JSON and YAML format:

• JSON OpenAPI File
• YAML OpenAPI File

Architecture

There are five key components to the API architecture.

User

This is the user that owns the resources (ClrCredentials) that are on the resource server. Also called a Resource Owner.

Web Browser

This is the web browser the user interacts with.

Client

This is the web application that interacts with the resource server on behalf of the user. Also called Consumer in the IMS Global Security Framework v1.1.

Authorization Server

This is a server that implements the OAuth 2.0 endpoints on behalf of the resource server. In many systems, the authorization server and the resource server are combined.

Resource Server

This is the server that has the protected resources (ClrCredentials). Also called Provider in the IMS Global Security Framework v1.1.

The role of each component during Registration, Obtaining Tokens, and Authenticating with Tokens are described below.

Secure REST Endpoints

All secure endpoint requests MUST be made over secure TLS 1.2 or 1.3 protocol.

All of the Secure REST Endpoints are protected by OAuth 2.0 access tokens as described in CLR Standard API Security.

Scopes

Each endpoint requires an access token with a specific CLR Standard scope as shown below.

getCredentials

Get issued ClrCredentials from the resource server for the supplied parameters and access token.

Request

GET /ims/clr/v2p0/credentials?limit={limit}&offset={offset}&since={since}

Request header, path, and query parameters

Responses

Allowed response codes and content types

Example: Sample getCredentials Request

GET /ims/clr/v2p0/credentials?limit=2&offset=0 HTTP/1.1
        Host: example.edu
        Authorization: Bearer 863DF0B10F5D432EB2933C2A37CD3135A7BB7B07A68F65D92
        Accept: application/json

Example: Sample getCredentials Response (line breaks for clarity)

HTTP/1.1 200 OK
        Content-Type: application/json
        X-Total-Count: 1
        Link: <https://example.edu/ims/clr/v2p0/credentials?limit=2&offset=2>; rel="next",

Paging

Pagination of getCredentials results is controlled by two query string parameters appended to the request. The response includes the following pagination headers.

If present, the Link header MUST support all of the following link relations (rel values):

Retry Behavior

Resource Servers MAY implement a Retry-After header to indicate a period of time to wait before attempting the request again.

If no Retry-After header is present and the response is non-2XX, it is recommended to retry the request in 30 minutes for an additional two attempts. After which, it MAY be desirable to alert the user that there is an issue with the connection (e.g. perhaps they need to reauthenticate or manually trigger the request when they believe services are back up).

CLR Standard API Security

The CLR Stardard API endpoints must use the methods outlined in Section 4, "Securing Web Services" of the IMS Global Security Framework v1.1. Clients and servers that give individual users control over access to their resources MUST use the OAuth 2.0 Authorization Code Grant method. A partial list of examples are shown in the table below:

Note: The API defined here is intended for Clients and servers that give individual users control over access to their resources. While system-to-system bulk transfers using OAuth 2.0 Client-Credentials Grant are expected to occur, it is out of scope for this version of the specification to define. Future versions of this specification may add explicit support for OAuth 2.0 Client-Credentials Grant.

Using OAuth 2.0 Authorization Code Grant

In scenarios where the learner or another third party is the resource owner, there will not be a pre-established trust relationship. Therefore the client credentials approach is insufficient. Instead you MUST use of OAuth 2.0 Authorization Code Grant.

Making a secured CLR Standard API request using authorization code grant comprises three steps:

1. ACG - Registration - Share configuration information between the client and the server.
2. ACG - Obtaining Tokens - Obtain an authorization code using a choreography between the client, web browser, user, and authorization server. Then request an access token by sending a request, using the previously obtained authorization code, to the Access Token service endpoint.
3. ACG - Authenticating with Tokens - Use the access token in the Authorization header of the API request

ACG - Registration

To get started, the client and authorization server must share the four pieces of information shown below. Clients and servers that implement the Authorization Code Grant (ACG) method of resource access MUST implement Dynamic Client Registration to share this information.

client_id

This is the public identifier for the communication exchange. Also called a Secret in the IMS Global Security Framework v1.1.

client_secret

This is the shared secret for the communication exchange. Also called a Secret in the IMS Global Security Framework v1.1.

List of Scopes

The list of scopes that identify the set of endpoints for which access permission is being requested.

OAuth 2.0 Access Token Service Endpoint

The endpoint from which the approved, requesting client can obtain an access token.

If the client and authorization server support Token Revocation, they should also share:

OAuth 2.0 Revocation Service Endpoint

The endpoint a client can use to revoke an access token.

ACG - Obtaining Tokens

Obtaining an access token using an authorization code has two steps:

• First obtain an authorization code using a choreography between the client, web browser, user, and authorization server - ACG - Authorization Request
• Then request an access token using the authorization code - Access Token Request

Once obtained, the client can freely re-use the access token up until the token's expiry time, so that the client need not repeat steps of obtaining an authorization code and requesting an access token for every API request. Token refresh is also available (see Token Refresh Request).

ACG - Authorization Request

After the client application is registered with the authorization server as described in Dynamic Client Registration, the client application then MAY initiate an authorization request as described in Section 4.2 of the IMS Global Security Framework v1.1 by redirecting the user to the authorizationUrl as declared in the resource server's Service Description Document (SDD).

In the OAuth 2.0 Security Best Practices document OAuth 2.0 Security Best Current Practice (draft-ietf-oauth-security-topics-11 the use of Proof Key for Code Exchange (PKCE) Proof Key for Code Exchange by OAuth Public Clients is recommended in order to (with the help of the authorization server) detect and prevent attempts to inject (replay) authorization codes into the authorization response. When using 1EdTech specifications, PKCE MUST be used to protect Authorization Code Grant based access. The PKCE has two stages:

• First the client MUST supply a code_challenge and code_challenge_method in the request for an authorization code. The authorization server is responsible for associating the code_challenge with the issued authorization code.
• Then the client MUST supply the code_verifier in the Access Token Request, and the authorization server verifies the code_verifier.

All of the authorization request parameters are encoded in the authorization request as query string parameters. The request MUST be made by redirecting the browser to the OAuth 2.0 Authorization endpoint. The request MUST use HTTPS with TLS 1.2 or 1.3 protocol.

Example: Sample ACG authorization request (line breaks for clarity)

HTTP/1.1 302 Found
Location: https://auth.example.com/authorize?
    client_id=4ad36680810420ed
    &response_type=code
    &scope=https%3A%2F%2Fpurl.imsglobal.org%2Fspec%2Fclr%2Fv2p0%2Fscope%2Fcredential.readonly%20offline_access
    &redirect_uri=https%3A%2F%client.example.com%2FAuthorize
    &state=26357667-94df-4a14-bcb1-f55449ddd98d
    &code_challenge=XeDw66i9FLjn7XaecT_xaFyUWWfUub02Kw118n-jbEs
    &code_challenge_method=S256

ACG - Authorization Response

If the redirect_uri matches a known client_id, the authorization server SHOULD present a UI asking the user to authenticate themself and grant the access request. The authorization server SHOULD display the client_name, client_uri, logo_uri, tos_uri, and policy_uri collected during Dynamic Client Registration to the user to help them decide whether to grant the access request.

If the user authorizes the client application to access their resources with the requested scopes, the authorization server MUST redirect the browser back to the redirect_uri with the code, scope, and state query string parameters.

The Authorization Code MUST be used only once. A lifetime for the authorization code of 600 seconds (10 minutes) is RECOMMENDED. If an authorization code is used more than once, the authorization server MUST deny the request and SHOULD revoke(when possible) all tokens previously issued based on that authorization code. The authorization code is bound to the client identifier and redirection URI.

Example: Sample ACG authorization response (line breaks for clarity)

HTTP/1.1 302 Found
        Location https://client.1edtech.org/Authorize?
          code=dcf95d196ae04d60aad7e19d18b9af755a7b593b680055158b8ad9c2975f0d86
          &scope=https%3A%2F%2Fpurl.imsglobal.org%2Fspec%ob%2Fv3p0%2Fscope%2Fcredential.readonly%20offline_access
          &state=26357667-94df-4a14-bcb1-f55449ddd98d

Authorization Error Response

If the authorization server does not recognize the client applications's redirection endpoint from a prior connection with this client application, the authorization server SHOULD inform the user of the error and MUST NOT automatically redirect to the web browser to the invalid redirection URI.

If the user denies the authorization request or if the request fails for reasons other than a missing or invalid redirection URI, the authorization server informs the client by adding the following parameters to the query component of the redirection URI.

Example: Sample authorization error response

HTTP/1.1 302 Found
        Location: https://client.1edtech.org/cb?error=access_denied&state=xyz

Access Token Request

With the supplied code, the client application SHOULD attempt to exchange the code for an access_token. The client application makes an authorization grant POST request to the tokenUrl as declared in the resource server's Discovery Document. The HTTP POST request MUST include a Basic authorization header with the client_id and client_secret provided in the registration response. The body of the token request MUST include the following form fields:

Example: Sample ACG token request (line breaks for clarity)

POST /token HTTP/1.1
        Host: auth.1edtech.org
        Authorization: Basic NDE2ZjI1YjhjMWQ5OThlODoxNWQ5MDA4NTk2NDdkZDlm
        Content-Type: application/x-www-form-urlencoded

        grant_type=authorization_code
          &code=7c7a73263ee14b2b48073d0615f286ec74f6636689046cb8dbede0b5e87a1338
          &redirect_uri=https%3A%2F%client.1edtech.org%2FAuthorize
          &scope=https%3A%2F%2Fpurl.imsglobal.org%2Fspec%2Fob%2Fv3p0%2Fscope%2Fcredential.readonly+offline_access
          &code_verifier=mYUQfKNgI1lSbY8EqtvNHLPzu0x%2FcVKO3fpWnX4VE5I%3D

Access Token Response

If the authorization server grants this request (see Section 5.1 in The OAuth 2.0 Authorization Framework for the detailed description), it returns HTTP 200 OK status code with content type "application/json" consisting of a JSON object containing the access token and its expiry lifetime (1EdTech recommends a default expiry lifetime of 3600 seconds, one hour, for access tokens), optionally a refresh token, and confirms the set of scopes supported by the access token:

Example: Sample ACG token response

HTTP/1.1 200 OK
        Cache-Control: no-store, no-cache, max-age=0
        Pragma: no-cache
        Content-Type: application/json; charset=UTF-8

        {
          "access_token": "863DF0B10F5D432EB2933C2A37CD3135A7BB7B07A68F65D92",
          "refresh_token": "tGzv3JOkF0XG5Qx2TlKWIA",
          "expires_in": 3600,
          "token_type": "Bearer",
          "scope": "https://purl.imsglobal.org/spec/ob/v3p0/scope/credential.readonly offline_access"
        }

Access Token Error Response

The authorization server MAY decide not to issue an access token. This could be because the request scopes are invalid, the credentials from the client may be invalid, etc. In this case the authorization server MUST return an HTTP 400 Bad Request status code with content type "application/json" consisting of a JSON object describing the error in the response body. The properties used to describe the error are:

Example: Sample access token error response

HTTP/1.1 400 Bad Request
        Content-Type: application/json;charset=UTF-8
        Cache-Control: no-store
        Pragma: no-cache

        {
          "error": "invalid_request"
        }

ACG - Authenticating with Tokens

After obtaining an access_token and optionally a refresh_token using the method above, a client application MAY issue request that access resources controlled by the user on the resource server using the access_token in the HTTP Authorization header HTTP Authentication: Basic and Digest Access Authentication with a Bearer Token The OAuth 2.0 Authorization Framework: Bearer Token Usage. For example, a "getCredentials" would look like this:

GET ims/clr/v2p0/credentials
        Host: example.edu
        Authorization: Bearer 863DF0B10F5D432EB2933C2A37CD3135A7BB7B07A68F65D92
        Accept: application/ld+json

Token Refresh

The recommended value of the access token's expires_in attribute is 3600 i.e. one hour. This means that the validity of the access token expires one hour after the time it was issued.

When requesting an access token as part of the Authorization Code Grant process, an authorization server MAY return a 'Refresh Token'. The refresh token can be used to obtain an access token using the same authorization grant: this is described in Section 6 of The OAuth 2.0 Authorization Framework. The use of the Refresh Token avoids the choreography for obtaining the credentials to gain access to the authorization server.

An Authorization Server is NOT REQUIRED to support token refresh.

Token Refresh Request

If the access_token is expired or about to expire, and the client application received a refresh_token, the client application can use OAuth 2.0 Token Refresh to get a new access_token and refresh_token.

The client makes a refresh POST request to the token endpoint by adding the following parameters using the "application/x-www-form-urlencoded" format in the HTTP request entity-body:

POST /token HTTP/1.1
        Host: auth.example.com
        Authorization: Basic czZCaGRSa3F0MzpnWDFmQmF0M2JW
        Content-Type: application/x-www-form-urlencoded

        grant_type=refresh_token&refresh_token=tGzv3JOkF0XG5Qx2TlKWIA&scope=https%3A%2F%2Fpurl.imsglobal.org%2Fspec%2Fclr%2Fv2p0%2Fscope%2credential.readonly

Token Refresh Response

If valid and authorized, the authorization server issues a new access token and optionally a new refresh token as described earlier in Access Token Response. If the request failed verification or is invalid, the authorization server returns an error response as described earlier in Access Token Error Response.

Token Revocation

There may be deployments in which revocation of an access token is useful. The Token Revocation process is based upon OAuth 2.0 Token Revocation. The client requests the revocation of a particular token by making an HTTP POST request (using TLS) to the token revocation endpoint URL. Note that OAuth 2.0 Token Revocation states that implementations MUST support the revocation of refresh tokens and SHOULD support the revocation of access tokens.

Token Revocation Request

The client constructs the request by including the following parameters using the "application/x-www-form-urlencoded" format in the HTTP request entity-body:

POST /revoke HTTP/1.1
        Host: server.example.com
        Authorization: Basic czZCaGRSa3F0MzpnWDFmQmF0M2JW
        Content-Type: application/x-www-form-urlencoded

        token=45ghiukldjahdnhzdauz&token_type_hint=refresh_token

Token Revocation Response

The authorization server responds with HTTP 200 OK status code if the token has been revoked successfully or if the client submitted an invalid token.

When the request for revocation is rejected, the authorization server returns an error response as described earlier in Access Token Error Response with an error code of "unsupported_token_type".

Dynamic Client Registration

Clients and servers that implement the Authentication Code Grant (ACG) method of resource access MUST implement the OAuth 2.0 Dynamic Client Registration Protocol OAuth 2.0 Dynamic Client Registration Protocol. There are two steps in this process:

1. Request the Service Description Document (SDD) from the resource server
2. Register with the authorization server

The client only needs to register a client_id with the authorization server once. Each user will use the same client_id when they request their own authorization code.

Request the Service Description Document

To start the registration process, the user supplies the client with the resource server's base URL. When presented with an unknown resource server the client MUST request the resource server's Service Description Document (SDD) as shown in getServiceDescription.

Upon receiving a SDD from a resource server, the client SHOULD respect the Cache-Control and Expires headers if present in the response and configure local cache to match the directives it declares. If directives include one of no-cache, no-store, the client SHOULD NOT cache the data for future interactions. If directives include max-age or if an Expires header is present, the client SHOULD cache the SDD data, if valid, up to the expiration indicated, either at the time indicated by the Expires header or max-age seconds from request time.

An Etag header MAY be offered with the SDD response. If so, after a resource's declared expiration, a client MAY include an If-None-Match header containing the value of the Etag to check if the resource is still fresh. If so the resource server may return a 304 Not Modified response status code, and a new Expires or Cache-Control header MAY be included, which the client SHOULD use to update the cache expiration.

Register with Authorization Server

With the Client Registration URL in hand (from the x-imssf-registrationUrl property of the SDD), the client SHOULD post a registration request to the authorization server. The registration request MUST comply with OAuth 2.0 Dynamic Client Registration Protocol OAuth 2.0 Dynamic Client Registration Protocol. The registration request MUST NOT require an Initial Access Token. Use of the 'Software Statement' is NOT RECOMMENDED. The client registration request is sent to the Client Registration URL. The request MUST be sent using HTTPS with TLS 1.2 or 1.3 protocol.

The properties of the JSON body MUST be implemented as described in the following table. All URLs MUST use HTTPS (e.g. https://example.com/logo.png) and all URLs MUST have the same hostname. All required properties MUST be present in the registration request in order for it to be accepted by the authorization server. Arrays MUST be used even when a single value is to be sent.

POST /connect/register HTTP/1.1
        Host: auth.example.com
        Accept: application/json
        Content-Type: application/json; charset=utf-8

        {
            "client_name": "Example Client Application",
            "client_uri": "https://client.example.com/",
            "logo_uri": "https://client.example.com/logo.png",
            "tos_uri": "https://client.example.com/terms",

            "redirect_uris": [

            "grant_types": [
                "authorization_code",

            ],
            "response_types": [
                "code"
            ],

        }

If the authorization server accepts the registration request, it will store the information provided in the request and respond HTTP 201 Created with a registration response that includes a set of client credentials for the client application to use when requesting access tokens. All the information provided by the client application MUST be returned to the client application, including modifications to the properties as the authorization server deems necessary. An example response looks like this:

HTTP/1.1 201 Created
        Content-Type: application/json; charset=utf-8

        {
            "client_id": "4ad36680810420ed",

            ],
            "scope": "https://purl.imsglobal.org/spec/clr/v2p0/scope/credential.readonly https://purl.imsglobal.org/spec/clr/v2p0/scope/credential.upsert https://purl.imsglobal.org/spec/clr/v2p0/scope/profile.readonly https://purl.imsglobal.org/spec/clr/v2p0/scope/profile.update offline_access"

The following table describes the properties present in the client registration response that were not included in the request. These are all REQUIRED properties.

When a registration error condition occurs, the authorization server returns an HTTP 400 status code (unless otherwise specified) with content type "application/json" consisting of a JSON object describing the error in the response body. The properties used are:

Proofs (Signatures)

This section describes mechanisms for ensuring the authenticity and integrity of CLR Standard documents and payloads. At least one proof mechanism, and the details necessary to evaluate that proof, MUST be expressed for a credential to be a verifiable credential; that is, to be verifiable.

Proof Formats

The proof formats included in this specification fall into two categories:

• JSON Web Token Proof - Somtimes called VC-JWT, this format has a single implementation: the credential is encoded into a JWT which is then signed and encoded as a JWS. The JSON Web Token proof is called an external proof because the proof wraps the credential object.
• Linked Data Proofs - The credential is signed and the signature is used to form a Proof object which is appended to the credential. This format supports many different proof types. These are called embedded proofs because the proof is embedded in the data.

Note: The issuer MAY use multiple proofs. If multiple proofs are provided, the verifier MAY use any one proof to verify the credential.

A third category of proof format called Non-Signature Proof is not covered by this specification. This category includes proofs such as proof of work.

JSON Web Token Proof Format

This proof format relies on the well established JWT (JSON Web Token) JSON Web Token (JWT) and JWS (JSON Web Signature) JSON Web Signature (JWS) specifications. A JSON Web Token Proof is a JWT signed and encoded as a Compact JWS string. The proof format is described in detail in Securing Verifiable Credentials using JOSE and COSE, refered from Section 5.13 "Securing Mechanism Specifications" of Verifiable Credentials Data Model v2.0. That description allows several options which may inhibit interoperability. This specification limits the options while maintaining compatibility with Verifiable Credentials Data Model v2.0 to help ensure interoperability.

Note: At the time of the completion of this specification, the JSON Web Token Proof Format of Verifiable Credentials Data Model v2.0 was undergoing a revision process. Securing Verifiable Credentials using JOSE and COSE will collect and display the result of this revision. The modifications resulting from the incompatibility of the revision with what is contained in this document will be added in future revisions.

Terminology

Some of the terms used in this section include:

JWT

"JSON Web Token (JWT) is a compact, URL-safe means of representing claims to be transferred between two parties. The claims in a JWT are encoded as a JSON object that is used as the payload of a JSON Web Signature (JWS) structure or as the plaintext of a JSON Web Encryption (JWE) structure, enabling the claims to be digitally signed or integrity protected with a Message Authentication Code (MAC) and/or encrypted." JSON Web Token (JWT)

JWS

"JSON Web Signature (JWS) represents content secured with digital signatures or Message Authentication Codes (MACs) using JSON-based data structures. Cryptographic algorithms and identifiers for use with this specification are described in the separate JSON Web Algorithms (JWA) specification and an IANA registry defined by that specification." JSON Web Signature (JWS)

JWK

"A JSON Web Key (JWK) is a JavaScript Object Notation (JSON) data structure that represents a cryptographic key." JSON Web Key (JWK)

Compact JWS

"A compact representation of a JWS." JSON Web Signature (JWS)

Overview

A JWS is a signed JWT with three parts separated by period (".") characters. Each part contains a base64url-encoded value.

JOSE Header

Describes the cryptographic operations applied to the JWT and optionally, additional properties of the JWT. JSON Web Signature (JWS)

JWT Payload

The JSON object that will be signed. In this specification, the JWT Payload includes the ClrCredential.

JWS Signature

The computed signature of the JWT Payload.

The JOSE Header, JWT Payload, and JWS Signature are combined to form a Compact JWS. To transform a credential into a Compact JWS takes 4 steps:

1. Create the JOSE Header, specifying the signing algorithm to use
2. Create the JWT Payload from the credential to be signed
3. Compute the signature of the JWT Payload
4. Encode the resulting JWS as a Compact JWS

The resulting JWS proves that the issuer signed the JWT Payload turning the credential into a verifiable credential.

When using the JSON Web Token Proof Format, the proof property MAY be ommitted from the ClrCredential. If a Linked Data Proof is also provided, it MUST be created before the JSON Web Token Proof Format is created.

Create the JOSE Header

The JOSE Header is a JSON object with the following properties (also called JOSE Headers). Additional JOSE Headers are NOT allowed.

Example: Sample JOSE Header with reference to a public key in a JWKS

  {
    "alg": "RS256",
    "kid": "https://example.edu/keys#key-1",
    "typ": "JWT"
  }

Create the JWT Payload

If you are going to use both external and embedded proof formats, add the embedded proofs prior to creating the JWT Payload.

Sign Nested Credentials

A ClrCredential has nested verifiable credentials. The Verifiable Credentials Data Model v2.0 specification does not specify how to encode a JWT Payload when the credential has nested credentials. To help ensure interoperability, this specification defines how to encode the JWT Payload with nested credentials.

The JSON Web Token Proof for each nested credential MUST be created prior to creating the JWT Payload for the parent credential. Because the JSON Web Token Proof for each nested credential is a Compact JWS string rather than a JSON object, the data model for a ClrCredential with VC-JWT proof is ClrCredentialJwtPayload.

1. Create a JSON object using the ClrCredentialJwtPayload data model.
2. Copy all of the claims from the parent credential to the new JSON object except for the nested credentials.
3. Process each nested credential:
   • If the nested credential is already signed with a JSON Web Token Proof, simply add the Compact JWS string to the new JSON object.
   • If the nested credential is not signed with a JSON Web Token Proof, sign it with a JSON Web Token Proof and add the resulting Compact JWS string to the new JSON object.
4. Use the new JSON object to form the JWT Payload.

Example: Sample ClrCredential prior to signing the nested AchievementCredentials

  {
    ...
    "credentialSubject": {
      "verifiableCredential": [
        {
          "id": "assertion1",
          ...
        },
        {
          "id": "assertion2",
          ...
        }
      ]
    }
  }

Example: Sample ClrCredential after signing the nested AchievementCredentials

  {
    ...
    "credentialSubject": {
      "verifiableCredential": [
        "header.payload.signature",
        "header.payload.signature"
      ]
    }
  }

JWT Payload Format

The JWT Payload is the JSON object with the following properties (JWT Claims). Additional standard JWT Claims Names are allowed, but their relationship to the credential is not defined.

Create the Proof

Note: 1EdTech strongly recommends using an existing, stable library for this step.

This section uses the follow notations:

• JOSE Header - denotes the JSON string representation of the JOSE Header.
• JWT Payload - denotes the JSON string representation of the JWT Payload.
• BASE64URL(OCTETS) - denotes the base64url encoding of OCTETS per JSON Web Signature (JWS).
• UTF8(STRING) - denotes the octets of the UTF-8 UTF-8, a transformation format of ISO 10646 representation of STRING, where STRING is a sequence of Unicode The Unicode Standard characters.
• The concatenation of two values A and B is denoted as A || B.

The steps to sign and encode the credential as a Compact JWS are shown below:

1. Encode the JOSE Header as BASE64URL(UTF8(JOSE Header)).
2. Encode the JWT Payload as BASE64URL(JWT Payload).
3. Concatenate the encoded JOSE Header and the encoded JSW Payload as A | "." | B.
4. Calculate the JWS Signature for C as described in JSON Web Signature (JWS).
5. Encode the signature as BASE64URL(JWS Signature).
6. Concatenate C and E as C | "." | E.

The resulting string is the Compact JWS representation of the credential. The Compact JWS includes the credential AND acts as the proof for the credential.

Verify a ClrCredential

Verifiers that receive a ClrCredential in Compact JWS format MUST perform the following steps to verify the embedded credential.

1. Base64url-decode the JOSE Header.
2. If the header includes a kid property, Dereference the kid value to retrieve the public key JWK.
3. If the header includes a jwk property, convert the jwk value into the public key JWK.
4. Use the public key JWK to verify the signature as described in "Section 5.2 Message Signature or MAC Validation" of JSON Web Signature (JWS). If the signature is not valid, the credential proof is not valid.

   1EdTech strongly recommends using an existing, stable library for this step.

5. Base64url-decode the JWT Payload segment of the Compact JWS and parse it into a JSON object.
6. Convert the value of the JWT Payload to a ClrCredential and continue with Verify a Credential VC-JWT Signature.

Note: Credentials created following Verifiable Credentials Data Model v2.0 (Verifiable Credentials Data Model v2.0) store the OpenBadgeCredential in the vc claim of the JWT Payload. In this case, the contents of the vc claim must be converted to an ClrCredential and continue with Verify a Credential VC-JWT Signature.

Verify a Credential VC-JWT Signature

• The JSON object MUST have the iss claim, and the value MUST match the id of the issuer of the ClrCredentialJwtPayload object. If they do not match, the credential is not valid.
• The JSON object MUST have the sub claim, and the value MUST match the id of the credentialSubject of the ClrCredentialJwtPayload object. If they do not match, the credential is not valid.
• The JSON object MUST have the nbf claim, and the NumericDate value MUST be converted to a DateTime, and MUST equal the validFrom of the ClrCredentialJwtPayload object. If they do not match or if the validFrom has not yet occurred, the credential is not valid.
• The JSON object MUST have the jti claim, and the value MUST match the id of the ClrCredentialJwtPayload object. If they do not match, the credential is not valid.
• If the JSON object has the exp claim, the NumericDate MUST be converted to a DateTime, and MUST be used to set the value of the validUntil of the ClrCredentialJwtPayload object. If the credential has expired, the credential is not valid.

Note: Credentials created following Verifiable Credentials Data Model v2.0 (Verifiable Credentials Data Model v2.0) have different names for attributes used in this process. Concretely, they have issuanceDate and expirationDate instead of validFrom and validUntil, respectively

Linked Data Proof Format

This standard supports the Linked Data Proof format. In order to pass conformance tests for this format issuers MUST use an option supported by the 1EdTech conformance test suite, which is currently limited to the Data Integrity EdDSA Cryptosuites v1.0 suite.

Note: Whenever possible, you should use a library or service to create and verify a Linked Data Proof.

Create the Proof

Attach a Linked Data Proof to the credential, for example by following these steps to use a proof with the Data Integrity EdDSA Cryptosuites v1.0 suite:

1. Create an instance of Multikey as shown in Section 2.1.1 DataIntegrityProof of Data Integrity EdDSA Cryptosuites v1.0.
2. Using the key material, sign the credential object as shown in Section 7.1 Proof Algothim of Data Integrity to produce a Proof as shown in Section 2.2.1 DataIntegrityProof of Data Integrity EdDSA Cryptosuites v1.0 with a proofPurpose of "assertionMethod".
3. Add the resulting proof object to the credential proof property.

Verify a ClrCredential Linked Data Signature

Verify the Linked Data Proof signature as shown in Section 7.2 Proof Verification Algorthim of Data Integrity.

Key Management

Issuers will need to manage asymmetric keys. The mechanisms by which keys are minted and distributed is outside the scope of this specification. See Section 6. Key Management of the IMS Global Security Framework v1.1.

Dereferencing the Public Key

All the proof formats in this specification, and all Digital Integrity proofs in general, require the verifier to "dereference" the public key from a URI. Dereferencing means using the URI to get the public key in JWK format. This specification allows the use of an HTTP URL (e.g. https://1edtech.org/keys/1) or a DID URL (e.g. did:key:123), but only requires HTTP URL support.

Verification and Validation

Verification is the process to determine whether a verifiable credential is an authentic and timely statement of the issuer or presenter respectively. This includes checking that: the credential conforms to the specification; the proof method is satisfied; and, if present, the status check succeeds. Verification of a credential does not imply evaluation of the truth of claims encoded in the credential.

Validation is the process of assuring the verifiable credential meets the needs of the verifier and other dependent stakeholders. Validating verifiable credentials is outside the scope of this specification.

Note: The 1EdTech Validator performs verification as described here.

ClrCredential Verification

This section applies to Verifiable Credentials with a type of "ClrCredential".

1. Check that the ClrCredential conforms to the specification:

   • If the ClrCredential has a credentialSchema property, and the type of the CredentialSchema object is "1EdTechJsonSchemaValidator2019", check that the credential conforms to JSON Schema as shown in 1EdTech JSON Schema Validator 2019. If it does not, the credential does not conform to the specification.

   • Check that the credentialSubject is identified by an id and/or an identifier. If neither is present, the credential does not conform to the specification.

   Note: ClrCredentials created following Verifiable Credentials Data Model v2.0 (Verifiable Credentials Data Model v2.0) have different names for attributes used in this process. Concretely, they have issuanceDate and expirationDate instead of validFrom and validUntil, respectively. The data model of these credentials and their corresponding JSON schemas, are described at verification-support-data-models and Derived Types, respectively.

2. Check that the proof method is satisfied:

   • If the ClrCredential is signed using the JSON Web Token Proof Format (VC-JWT), verify the signature as shown in Verify a ClrCredential. If the ClrCredential is signed using an embedded proof, verify the signature as shown in Verify a ClrCredential Linked Data Signature. If the signature cannot be verified, the proof method is not satisfied.

   Note: The ClrCredential may have a VC-JWT proof and one or more Linked Data proofs. In this case, the Linked Data proofs will be attached to the ClrCredential in the signed JWT Payload. You may accept any one proof for verification. You do not need to verify all the signatures.

3. Refresh the ClrCredential:

   Note: Refresh must be completed after checking the proof so that the verifier is not spoofed into receiving a refreshed ClrCredential from a bad actor.

   • If the refreshService property is present, and the type of the RefreshService object is "ImsCredentialRefresh", refresh the credential as shown in 1EdTech Credential Refresh Service and then repeat steps 1 and 2. If the refresh is not successful, continue the verification process using the original ClrCredential.

   Note: Only perform Refresh once. That is, do not complete Refresh a second time even if the refreshed ClrCredential also has a refreshService defined.

4. Check the status:

   • A Credential is revoked if the credentialStatus property is present, and the type of the CredentialStatus object is "BitstringStatusListEntry", and if the Credential has been revoked as shown in Bitstring Status List v1.0.
   • If the current date and time is before the validFrom, the ClrCredential is not yet valid.
   • If the current date and time is after the validUntil, the ClrCredential is expired.

   Note: ClrCredentials created following Verifiable Credentials Data Model v2.0 (Verifiable Credentials Data Model v2.0) have different names for attributes used in this process. Concretely, they have issuanceDate and expirationDate instead of validFrom and validUntil, respectively. The data model of these credentials and their corresponding JSON schemas, are described at verification-support-data-models and Derived Types, respectively.

5. Optionally verify the subject (recipient):

   Note: This step is optional, but RECOMMENDED when the ClrCredential has been exchanged with the verifier as one of the CLR Standard Document Formats.

   • A ClrCredential is about a person called the recipient. The recipient is identified in the credentialSubject (see ClrSubject) by id and/or one or more identifier (see IdentityObject). The id or identifier value to use for verification must be shared with the verifier in an out-of-band process such as by email. This is called the known value.
   • To verify the recipient using a known id, simply compare the known id with the id in the ClrSubject. If they are equal then the recipient is verified.
   • To verify the recipient using a known identifier such as email address follow these steps shown in Verify the Recipient Using an Identifier. If you find a match then the recipient is verified.
   • If no match is found, the recipient is not verified.

6. Verify nested verifiable credentials:

   • A ClrCredential usually contains nested verifiable credentials in the credentialSubject. A ClrCredential may also contain nested EndorsementCredentials. If the nested verifiable credential has a type of "AchievementCredential" or "OpenBadgeCredential", verify the nested credential as shown in section "OpenBadgeCredential Verification" of the Open Badges Specification v3.0. If the nested verifiable credential has a type of "EndorsementCredential", verify the nested credential as shown in section "EndorsementCredential Verification" of the Open Badges Specification v3.0.

If all the above steps pass, the ClrCredential may be treated as verified.

Verify the Recipient Using an Identifier

The known identifier MUST be a plaintext string value. The known identifier type MUST be one of the types in IdentifierTypeEnum or an extension type. For example, if the known identifier is an email address, the known identifier type is emailAddress.

The ClrCredential issuer may include multiple identifiers that can be used for verification. The verifier should compare the known identifier (e.g. known email address) with all the identifiers included by the issuer until a match is found.

1. If identifier.identityType does not match the known identifier type, skip to the next identifier.
2. If identifier.hashed is true, calculate the known identifier IdentityHash using the known identifier and the identifier.salt. If the known identifier IdentityHash matches the identifier.identityHash, the recipient is verified.
3. If identifier.hashed is false, and if the known identifier matches the identifier.identityHash, the recipient is verified.

Credential equality and comparison algorithm

Credential equality and comparison is the process to determine whether a verifiable credential is semantically equivalent to another one.

A Host SHOULD treat a credential as the same as another when both the issuer id and the ClrCredential id are equal after unescaping of any percent encoded characters Uniform Resource Identifier (URI): Generic Syntax followed by truncation of leading and trailing whitespace.

If the two credentials are equal according to the above, then the credential with the newer validFrom is the more up-to-date representation and could be interpreted as a replacement of the prior issued credential.

Examples

Equality

Credentials A and B are equal since they have the same id and the same issuer.id.

The credential C is the up-to-date representation because it has a more recent validFrom (2010-03-01T00:00:00Z).

Verifiable Credentials Extensions

The Verifiable Credentials Data Model v2.0 standard defines several types of extensions to enable "permissionless innovation". Conformant extensions are tracked in the Verifiable Credentials Extension Registry.

This standard references four VC Extensions:

• A Proof Method called DataIntegrityProof defined at Data Integrity EdDSA Cryptosuites v1.0
• A Refresh Method called 1EdTech Credential Refresh Service
• A Data Schema Validation Method called 1EdTech JSON Schema Validator 2019

Serialization

The data model as described in Appendix Data Models is the canonical structural representation of an Comprehensive Learner Record verifiable credential (ClrCredential). All serializations are representations of that data model in a specific format. This section specifies how the data model is realized in JSON-LD and plain JSON.

JSON

The data model can be encoded in Javascript Object Notation (JSON) The JavaScript Object Notation (JSON) Data Interchange Format by mapping property types in the Data Model to JSON types as follows:

• Numeric values representable as IEEE Standard for Floating-Point Arithmetic MUST be represented as a JSON Number.
• Boolean values MUST be represented as a JSON Boolean.
• Sequence values MUST be represented as an JSON Array, NOT as a single value.
• Unordered sets (i.e. 0..* and 1..* multiplicities) of values MUST be represented as an JSON Array, NOT as a single value.
• Complex types (i.e. not primitive types or derived types) MUST be represented as an JSON Object, NOT as a URI.
• Other values MUST be represented as a JSON String.
• Null values and empty arrays MUST be ommitted from the serialized JSON. This includes empty Arrays.

JSON-LD

JSON-LD 1.0 is a JSON-based format used to serialize Linked Data. The syntax is designed to easily integrate into deployed systems already using JSON, and provides a smooth upgrade path from JSON to JSON-LD 1.0. It is primarily intended to be a way to use Linked Data in Web-based programming environments, to build interoperable Web services, and to store Linked Data in JSON-based storage engines.

Instances of the data model are encoded in JSON-LD 1.0 in the same way they are encoded in JSON (Section JSON), with the addition of the @context property. The JSON-LD context is described in detail in the JSON-LD 1.0 specification and its use is elaborated on in Section Extending and Profiling this Standard.

Multiple contexts MAY be used or combined to express any arbitrary information about verifiable credentials in idiomatic JSON. The JSON-LD context for all verifiable credentials, available at https://www.w3.org/ns/credentials/v2, is a static document that is never updated and can therefore be downloaded and cached client side. The associated vocabulary document for the Verifiable Credentials Data Model is available at https://www.w3.org/2018/credentials. The JSON-LD context for Comprehensive Learner Record verifiable credentials is available at https://purl.imsglobal.org/spec/clr/v2p0/context-2.0.1.json. The associated vocabulary document for the Comprehensive Learner Record Data Model is available at https://purl.imsglobal.org/spec/clr/v2p0/context/clr_v2p0.html. Comprehensive Learner Record verifiable credentials MUST be serialized with both JSON-LD contexts.

Note: Though this specification requires that a @context property be present, it is not required that the value of the @context property be processed using JSON-LD. This is to support processing using plain JSON libraries, such as those that might be used when the verifiable credential is encoded as a JWT. All libraries or processors MUST ensure that the order of the values in the @context property is what is expected for the specific application. Libraries or processors that support JSON-LD can process the @context property using full JSON-LD processing as expected.

Example: JSON-LD @context serialization

"@context": [
    "https://www.w3.org/ns/credentials/v2",
    "https://purl.imsglobal.org/spec/clr/v2p0/context-2.0.1.json",
    "https://purl.imsglobal.org/spec/ob/v3p0/context-3.0.3.json"
  ]

Compacted document form

JSON-LD 1.1 Processing Algorithms and API defines a compaction process for JSON-LD 1.1 documents, applying a context to shorten several fields of the document. The purpose of compaction is making the document to be represented in a form that is tailored to the use of the JSON-LD document directly as JSON.

One of the transformations made by this compaction process is representing properties with only one value as string or maps, while properties with multiple values are represented as an array of strings or maps.

The JSON-LD binding for Comprehensive Learner Record verifiable credentials (ClrCredential) MAY use singular values compaction in some attributes in the data model, such they can be expressed as a string – when having only one value – or an array of strings – when having multiple values.

The properties that may be compacted are listed in the following table:

Data Models

ClrCredential

A ClrCredential is a CLR with all the properties needed to conform with a Verifiable Credential as defined in the Verifiable Credentials Data Model v2.0.

This class can be extended with additional properties.

ClrSubject

A collection of information about the learner that is the subject of this CLR credential.

This class can be extended with additional properties.

Association

An Association describes the semantic relationship between two achievements and the credentials that assert those achievements.

AssociationType Enumeration

A vocabulary of association types. Associations describe the semantic relationship between two achievements.

The data models in this section are specific to Comprehensive Learner Record Standard v2.0.

ClrCredentialJwtPayload

Represents a Comprehensive Learner Record (CLR) expressed to conform with the JSON Web Token Proof Format Securing Verifiable Credentials using JOSE and COSE. Nested credentials are represented as Compact JWS strings.

This class can be extended with additional properties.

ClrSubjectJwtPayload

Claims about the subject learner.

This class can be extended with additional properties.

The data models in this section are used by the JSON Web Token Proof Format applied to a ClrCredential.

GetClrCredentialsResponse

The data models in this section are used by the CLR Standard API.

Achievement

A collection of information about the accomplishment recognized by the Assertion. Many assertions may be created corresponding to one Achievement.

This class can be extended with additional properties.

AchievementCredential

AchievementCredentials are representations of an awarded achievement, used to share information about a achievement belonging to one earner. Maps to a Verifiable Credential as defined in the Verifiable Credentials Data Model v2.0. As described in Proofs (Signatures), at least one proof mechanism, and the details necessary to evaluate that proof, MUST be expressed for a credential to be a verifiable credential. In the case of an embedded proof, the credential MUST append the proof in the proof property.

This class can be extended with additional properties.

AchievementSubject

A collection of information about the recipient of an achievement. Maps to Credential Subject in Verifiable Credentials Data Model v2.0.

This class can be extended with additional properties.

Address

An address for the described entity.

This class can be extended with additional properties.

Alignment

Describes an alignment between an achievement and a node in an educational framework.

This class can be extended with additional properties.

Criteria

Descriptive metadata about the achievements necessary to be recognized with an assertion of a particular achievement. This data is added to the Achievement class so that it may be rendered when the achievement assertion is displayed, instead of simply a link to human-readable criteria external to the achievement. Embedding criteria allows either enhancement of an external criteria page or increased portability and ease of use by allowing issuers to skip hosting the formerly-required external criteria page altogether. Criteria is used to allow would-be recipients to learn what is required of them to be recognized with an assertion of a particular achievement. It is also used after the assertion is awarded to a recipient to let those inspecting earned achievements know the general requirements that the recipients met in order to earn it.

This class can be extended with additional properties.

EndorsementCredential

A verifiable credential that asserts a claim about an entity. As described in Proofs (Signatures), at least one proof mechanism, and the details necessary to evaluate that proof, MUST be expressed for a credential to be a verifiable credential. In the case of an embedded proof, the credential MUST append the proof in the proof property.

Evidence

Descriptive metadata about evidence related to the achievement assertion. Each instance of the evidence class present in an assertion corresponds to one entity, though a single entry can describe a set of items collectively. There may be multiple evidence entries referenced from an assertion. The narrative property is also in scope of the assertion class to provide an overall description of the achievement related to the assertion in rich text. It is used here to provide a narrative of achievement of the specific entity described. If both the description and narrative properties are present, displayers can assume the narrative value goes into more detail and is not simply a recapitulation of description.

This class can be extended with additional properties.

The data models in this section are shared by Open Badges Specification v3.0 and Comprehensive Learner Record Standard v2.0.

Extending and Profiling this Standard

This standard can be extended in three ways:

• Extend the Data Model with new classes and new properties to existing extensible classes
• Extend the Extensible Enumerated Vocabularies in the Data Model
• Extend the API with new endpoints and new responses to existing endpoints

Extensions SHOULD be presented to the Comprehensive Learner Record project group for review and socialization.

Extensions MUST NOT be required.

Extensions WILL NOT be tested during conformance testing.

This standard can also be profiled. In general, profiling is used to:

• Refine which endpoints are used and which operations are supported for each endpoint
• Refine the data models by increasing the constraints on the base definitions

Extending the Data Model

A data model extension may add new classes to the Data Model and/or new properties to existing extensible classes. Extensible classes are identified by the phrase, "This class can be extended with additional properties" shown at the bottom of the table of properties. For example, the Alignment class is extensible.

The extension SHOULD be documented with the following artifacts:

• A description of the extension and the problem it solves. Ideally the description would include a use case formatted like the use cases in this specification.
• Definitions of the new classes being introduced. Each definition MUST include the class name, description, and properties; and indicate whether the class can be extended.
• Definitions of the new properties being introduced. The each definition MUST include the property name, type, and description; and indicate whether the property is required.
• A JSON Schema file that defines the new classes and/or properties. The JSON Schema file MUST be hosted on a publicly accessible server with no CORS restrictions.
• A JSON-LD Context file that defines the new classes and/or properties. The context file MUST be hosted on a publically accessible server with no CORS restrictions.
• Ideally a modified version of the CLR Standard OpenAPI file that includes the new classes and/or properties.

To use the extension implementers MUST do the following:

• Include the JSON-LD Context file URL in the `@context` property. See Serialization.
• Include the JSON Schema file URL in the `credentialSchema` property.

Extending Enumerated Vocabularies

All extensible enumerated vocabularies may be extended with custom terms. Extensible vocabularies are identified by the phrase, "This enumeration can be extended with new, proprietary terms" shown at the bottom of the table of terms. For example, the AchivementType enumeration is extensible.

Extended terms MUST start with the prefix "ext:". For example, `ext:MyTerm`.

The extended terms SHOULD be documented with the following artifacts:

• A description of the extension and the problem it solves. Ideally the description would include a use case formatted like the use cases in this specification.
• Definitions of each extended term. Each definition MUST include the extended term (e.g. "ext:MyTerm") and description.
• A JSON Schema file is not required. The existing JSON Schema for extensible vocabularies allows extended terms that follow the naming rule above.
• You MAY include a JSON-LD Context file that defines the new extended terms. If one is supplied, it MUST be hosted on a publically accessible server with no CORS restrictions.

To use the extended vocabulary implementers MAY do the following:

• Include the JSON-LD Context file URL in the `@context` property. See Serialization.

Extending the API

An API extension may add new endpoints (with or without new scopes) to the CLR Standard API and/or new responses to the existing endpoints.

The extension SHOULD be documented with the following artifacts:

• A description of the extension and the problem it solves. Ideally the description would include a use case formatted like the use cases in this specification.
• Definitions of the new endpoints being introduced. Each definition MUST include the endpoint name, description, HTTP Method, URL format, required request query parameters (if any), required request headers, required request payload (if any), required responses, and required response headers.
  • The URL format MUST following 1EdTech naming conventions. Specifically, the path "/ims/clr/v2p0/" must precede the final URL segment. For example, "/ims/clr/v2p0/myendpoint".
  • The definition must indicate if the endpoint requires authorization. If it does, the definition must define the scope that is required. New endpoints that require authorization MUST follow the requirements shown in CLR Standard API Security.
  • Each required query parameter definition MUST include the parameter type and description.
  • Each required request header definition MUST include the header and a description.
  • A required request payload definition MUST include the payload type.
  • Each required request response definition MUST include the HTTP Status Code, payload type (if any), and description. Non-successful responses (i.e. HTTP Status Code >= 400) SHOULD use the Imsx_StatusInfo payload.
  • Each requied response header defintion MUST include the header and a description.
• Definitions of the new responses to existing endpoints. The each definition MUST include the HTTP Status Code, payload type (if any), and description. Non-successful responses (i.e. HTTP Status Code >= 400) SHOULD use the Imsx_StatusInfo payload.
• Ideally an OpenAPI file that describes the new endpoints and/or responses to existing endpoints.

Profiles

Profiling is the process by which an 1EdTech specification is tailored to meet the requirements of a specific community: the community could be a reflection of a market sector, a geographic location, etc. An example of such a community is the Norwegian K-12/Schools for whom a profile of the 1EdTech OneRoster 1.2 specification has been created. The process of profiling starts with the corresponding base specification and defines a set of new constraints to make the subsequent modified specification better fit the requirements of the target community. Once the profile has been defined, the next step is to create the corresponding Conformance Test Systems and Certification process for that profile: these will be modified versions of the equivalents created for the base specification. It is recommended that profiling is undertaken within 1EdTech so that the 1EdTech model driven specification tools can be used.

A profile is the product produced by the process of specification Profiling. A Profile of a 1EdTech specification consists of a set of new constraints. In general a 1EdTech specification enables a wide range education and learning workflows, processes and practices. A profile is designed to establish and impose best practices for the target community. A profile MUST only increase constraints i.e. it MUST NOT relax constraints in the base specification. For example the multiplicity of a property in the data model MAY be changed from [1..\] (required and permitting many) to [1..1] (required and only one) but MUST NOT become [0..\] (optional and permitting many). The most common profiling changes include more strict data typing, changes to enumerations, vocabulary changes, prohibition of endpoints and creation of new endpoints. A profile could make use of the extension capabilties to extend the specification to support new features. The key objective of a rofile is to remove, wherever possible, interoperability uncertainty e.g. by removing optionality.

It is strongly recommended that a profile of this standard is undertaken either by, or with the close support, of 1EdTech. However, no matter who is responsible for creating the profile artefacts (documents, schemas, etc.), it is strongly recommended that 1EdTech specification tools are used. This will ensure that the artefacts are consistent with the base specifications and that useful support documentation is automatically produced e.g. creation of a document that summarises the differences between the base specification and the profile.

AchievementCredential

AchievementCredentials are representations of an awarded achievement, used to share information about a achievement belonging to one earner. Maps to a Verifiable Credential as defined in the Verifiable Credentials Data Model v2.0. As described in Proofs (Signatures), at least one proof mechanism, and the details necessary to evaluate that proof, MUST be expressed for a credential to be a verifiable credential. In the case of an embedded proof, the credential MUST append the proof in the proof property.

Criteria

Descriptive metadata about the achievements necessary to be recognized with an assertion of a particular achievement. This data is added to the Achievement class so that it may be rendered when the achievement assertion is displayed, instead of simply a link to human-readable criteria external to the achievement. Embedding criteria allows either enhancement of an external criteria page or increased portability and ease of use by allowing issuers to skip hosting the formerly-required external criteria page altogether. Criteria is used to allow would-be recipients to learn what is required of them to be recognized with an assertion of a particular achievement. It is also used after the assertion is awarded to a recipient to let those inspecting earned achievements know the general requirements that the recipients met in order to earn it.

EndorsementCredential

A verifiable credential that asserts a claim about an entity. As described in Proofs (Signatures), at least one proof mechanism, and the details necessary to evaluate that proof, MUST be expressed for a credential to be a verifiable credential. In the case of an embedded proof, the credential MUST append the proof in the proof property.

Evidence

Descriptive metadata about evidence related to the achievement assertion. Each instance of the evidence class present in an assertion corresponds to one entity, though a single entry can describe a set of items collectively. There may be multiple evidence entries referenced from an assertion. The narrative property is also in scope of the assertion class to provide an overall description of the achievement related to the assertion in rich text. It is used here to provide a narrative of achievement of the specific entity described. If both the description and narrative properties are present, displayers can assume the narrative value goes into more detail and is not simply a recapitulation of description.

Profile

A Profile is a collection of information that describes the entity or organization using Open Badges. Issuers must be represented as Profiles, and endorsers, or other entities may also be represented using this vocabulary. Each Profile that represents an Issuer may be referenced in many BadgeClasses that it has defined. Anyone can create and host an Issuer file to start issuing Open Badges. Issuers may also serve as recipients of Open Badges, often identified within an Assertion by specific properties, like their url or contact email address.

VerifiableCredential

A Verifiable Credential as defined in the Verifiable Credentials Data Model v2.0. As described in Proofs (Signatures), at least one proof mechanism, and the details necessary to evaluate that proof, MUST be expressed for a credential to be a verifiable credential. In the case of an embedded proof, the credential MUST append the proof in the proof property.
