It is like my Christmas present came early this year!
After a successful IMS quarterly meeting in Commerce, Texas in the second week of November where we demonstrated prototype interoperable implementations of LTI v1.1 with Moodle 2.2, Sakai 2.9 and SPV Software’s Building Block and PowerLink, the spec passed the threshold test for going to Public Draft.
The primary new feature for LTI v1.1 is the ability to send grades back from an external tool to an LMS.
In the IMS process, when a specification reaches Public Draft it is very mature and nearly complete and folks should review it quickly to see if there are any issues because it is very likely to be final in the next 30-60 days.
