    • Personalisation
      • Depends on self-asserted claims by user.
    • Common presence across services.
      • Depends on universal identifier – with consent of user.

      • OpenID reflects trends of the Open Web.... and those of users and learners.
      • Open content, collaboration, linked-data, RESTful APIs, social software, microformats.

      • Learners want to use the services they choose, know, and like to use.
      • Provides access to best-of-breed services.
      • Staff want to find the best, and most appropriate services for themselves & students .
      • Campuses can't provide diverse enough set of services.
    ALT-C 2008 Sponsor Session September 2008
  • 14. Scenario 1:
      • Universities issue OpenIDs
      • Easy to do
      • Inferred membership of organisation...
      • http://openid.bath.ac.uk/user
      • Identifier not portable between organisations
    ALT-C 2008 Sponsor Session September 2008
  • 15. Scenario 2:
      • Association of an existing OpenID with a ‘formal’ University identity
      • Also easy to do
      • Lifelong learning
      • Collaboration with peers
      • ‘ Hides’ OpenID from service providers
    ALT-C 2008 Sponsor Session September 2008
  • 16. Scenario 3:
      • Hybrid model: OpenID as a pointer to a formal identity
    ALT-C 2008 Sponsor Session September 2008
  • 17.  
  • 18. Service Provider (1) OpenID request http://dno.myopenid.com (4) Formal claims (3) Shibboleth request Informal claims + pointer to ‘formal’ university identity provider (2)
  • 19. Conclusions
    • Gives users choice .
    • Fits in with a user-centric, Web 2.0 view of the world.
    • Bridge to a more diverse range of services.
    • Life-long learning identity association.
    • Users can build up personal portfolio of services.
    • Institutional, non-institutional mash-ups.
    ALT-C 2008 Sponsor Session September 2008
  • 20. Considerations
    • It's not a universal solution.
      • Or is it?
      • Good for the techies/Web 2.0 people.
    • Not without risks.
      • Service levels and continuity
      • Data-loss – too much dependency on external services.
