Dear all,Seamless Access Contract Language Working Group with both library and publishers representatives led by Jason Griffey from NISO released  Entity Category Use Case Scenarios document for comments. The goal of the document is to outline the various use cases in order to determine the overlap between user access, authentication and authorization, attribute release, and entity categories used in the federated authentication communication between the Identity Provider and the Service Provider. These use cases will be used to ground the contract language in real world examples.
