Caliper Analytics Connector Service

The IMS Caliper Analytics specification describes a way learning systems can capture data from learning interactions and share that data with data stores. While many of these interactions may take place within an LTI platform, in order to obtain a more holistic picture of a learner's activities, it is important not to ignore those interactions that may take place within any connected LTI tool deployments. Thus, it is important not only to instrument the LTI platform, but also the LTI tools. Indeed, for the analytics data to be most useful, the activity in the tools should be correlated with the activity in the platform, during the same logical "session". IMS is developing this LTI Caliper Analytics Connector Service specification to allow a platform to more easily inform their deployed external LTI tools of a common place all these deployed tools can send their Caliper Analytics data in a secure way. Using the Caliper Connector Service URL communicated to tools via LTI messages, tools can send Caliper event and entity data to a Caliper Endpoint common to the LTI context in which users' activity occurs.
