[Building Sakai] Example how to use LTI Basic Outcomes Service

[csev]

Yup - it is all documented in the IMS site.

http://www.imsglobal.org/developers/LTI/test/v1p1/index.php

And some local bits are documented here:

https://source.sakaiproject.org/svn/basiclti/trunk/basiclti-docs/resources/docs/sakai_basiclti_outcomes.doc

But that is a little out of date.

I should probably add a improve that documentation task to myself :)

The Sakai 2.8 outcomes look quite different than the Sakai 2.9 / LTI 1.1 outcomes.   But the data model is the same and a tool can easily support both approaches because there are signals in the POST data as to which version of the service is supported.
