[Building Sakai] LTI roles in portfolio sites

[sean.keesler]

I'm noticing that the roles passed along in the LTI tool seem limited to that of a "Learner" and a "Instructor". In a normal course site, the difference between learners and students, teachers and instructors are just a matter of semantics. Even TA's could be rationalized to be playing the role of an "Instructor" for most purposes.


However, in portfolio site there are a few different roles (Coordinators, Evaluators, Reviewers and Participants) with different parts to play in some portfolio processes. 


When I test the LTI tool, I see the following mapping:


Sakai role                LTI Role
--------------------------------------------------------
CIG Coordinator       Instructor
Reviewer                 Learner
Participant               Learner
Evaluator                Learner


I'd like to be able to adjust this for our purposes and perhaps suggest that a different default behavior may be needed OOTB.


How would one configure a mapping between Sakai site roles and roles passed as part of the launch request?
