Learning Tools Interoperability
Learning Tools Interoperability (LTI) is a standard created by the IMS Global Learning Consortium. [1]
It’s primary purpose is to connect learning systems such as an LMS with external service tools in a standard way across learning systems. The standard describes the connecting system as a LTI Tool Consumer and the connected tool as a LTI Tool Provider.
Terminology
LTI Consumer: This is the service that is consuming the tool. Typically this is a learning management system (LMS) or user portal. The LTI Consumer provides user information and context to to the LTI Tool Provider. Additionally the LTI Consumer provides authentication vouching for the user to the LTI Tool Provider. [2]
LTI Tool Provider: This is the service providing the service to the LTI Consumer. This can be an OnPrem or Hosted tool that is hosted outside the LTI Consumer. <ref name="LTI1">
