The Names and Role Provisioning Services is based on IMS Learning Information Services (LIS) [LIS, 11] and W3C Organization Ontology [W3C, 14 ORG]. It is concerned with providing access to data about users’ roles within organizations, a course being an example of an organization. So a very common purpose for this service is to provide a roster (list of enrolments) for a course.
All requests are secured using OAuth signatures generated with the existing LTI credentials. [OBH, 11]
