Tsugi is a framework that handles much of the low-level detail of building multi-tenant tool that makes use of the IMS Learning Tools Interoperability™ (LTI)™ and other learning tool interoperability standards. The Tsugi Framework provides library and database code to receive and model all of the incoming LTI data in database tables and sets up a session with the important information about the LMS, user, and course.

Tsugi is currently an incubation project in the Apereo Foundation.
