Issues with returning LTI results to Moodle

[davemckain]

The Glasgow folks have been trying out the LTI result return with their institutional Moodle, which has brought up some issues that we're currently working on.

Points so far:

1. The LTI module in Moodle uses some PHP that doesn't work well on their server. Niall and Stephen V are working on a patch for this.
2. The POX result XML coming back from Moodle is a different namespace (http://www.imsglobal.org/lis/oms1p0/pox) from that stated in the LTI specification (http://www.imsglobal.org/services/ltiv1p1/xsd/imsoms_v1p0).

I've patched my code to ignore the namespace URI of the POX response XML. I've also done some wire logging on my LTI result HTTP requests and tuned the headers to be as friendly as possible for the TC at the other end.
