A Framework for Building Learning Tools and Content

Welcome to the Tsugi project. Our goal is to build a scalable multi-tenant "tool" hosting environment based on the emerging IMS standards to help move the industry toward a Next Generation Digital Learning Environment (NGDLE).

You can play with the Tsugi developer console on this site:

Please do not use the testing key/secret for anything that is production. The data associated with the key "12345" is regularly cleared off this system without any notification.

If you want to use Tsugi tools in your courses, see sites like www.wa4e.com or www.py4e.com. Log into the site, and select "LMS Integration" to apply for a key that you can safely use in your classes.

Tsugi In Production

If you have a production instance of Tsugi and would like to be listed here, please contact me or send a Pull Request for this page via GitHub. If you provide me with a mailing address, I will send you a Tsugi Swiss Army Knife (while supplies last).

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.

If you are interested in Supporting the Tsugi Effort, please let us know.

Tsugi is currently an incubation project in the Apereo Foundation.

Learning Tools Interoperability® (LTI®) is a trademark of IMS Global Learning Consortium, Inc. in the United States and/or other countries.
