Link and Content Service

The Link and Content Service allows a tool to know and manage its assets that are engaged in a given platform's learning context. The primary use case of this specification is to manage a tool's LTI Resource Links, but it affords platforms the ability to support the management of other types of tool assets. While this specification is related to the LTI Advantage Deep Linking UI flow [[LTI-DL-Spec]], which allows the user to import the tool's assets through a UI flow, it does not preclude assets that were not imported using Deep Linking. The assets may have been manually added, imported from cartridges, or come from a copy. What matters is the asset is explicitly bound to the tool. This specification is also a sibling of the Line Item Service within the LTI Assignment and Grades Service [[LTI-AGS-Spec]]. While the latter allows for the management of line items, this specification allows for the management of LTI Resource Links and, optionally, other kinds of Tool content.
