RE: DID use case

I would think it would be easier for Universities A just to tell their libraries to honor a cert that says a student is in university B and C, and visa versa.  Then if a university wants to stop allowing university B students from having access, they merely stop honoring that credential.  That is, bilateral agreements seem to work much better for this usage than making up a shared resource credential.

Subject: DID use case

Hi,

Here is a use case for DID:

Institutional Library Users (adapted from http://ra21.org/)

A member of an authorized user community, such as a University Library, gains access to subscription resources provided by multiple publishers. When the user is within the library's physical walls, she can access the materials with her authorized credentials. When she is on her mobile phone, she can access the same materials remotely. She is required to provide her credentials as a member of the authorized community to access the materials without paying a fee for the content.

Notes: There could be a single identifier that students use to sign in to library resources, no matter which attend.  The IDs are NOT about the privileges attached to their relationship with any given university, nor are they attached to the relationship between a university and a resource provider. Those privileges would be associated with such IDs, but the IDs themselves are independent.
Scenario

  *   Universities A, B, C issue a "shared resource" credential to their students
  *   Students with the shared resource credential have access to libraries that recognize it.
  *   University D would like to issue the shared resource credential to their students
  *   University A,B,C give University D tools to issue the shared resource credential
  *   University B leaves the group, and their students are no longer allowed access to the shared resources
