Implementing support for the LTI Course Groups Service

[Charles Severance]

Hi all,

I have been implementing the 1EdTech(IMS) Course Groups Service this week in Sakai and Tsugi:

https://www.imsglobal.org/spec/lti-gs/v1p0

This is a nice spec as it allows the LMS to communicate the membership of groups within courses.  For now, in Tsugi tools can ask for and get the groups is the LMS provides the service end point.  In many ways, it is like the support in Tsugi for the Names and Roles Provision Service (NRPS).

The change requires a database upgrade - but I have invented a new mechanism to make the simplest of DB schema upgrades pretty seamless so I am just going to drop this into master.  But as a precaution, I have a “run back to safety” branch for Tsugi:

If you upgrade to master and see something weird let me know right away.

P.S. Tom, I will get to making broken LTI 1.1 transition claims non-fatal shortly after I land these changes since they were inflight.  It will be easy and quick.

Hi Dr. Chuck,

That sounds quite interesting as well. And thank you for the heads up.

Cheers,

Tom
