TheUMA V2.0 specifications have exited their four-week"WG last call" period, and the Work Group has published an initial set of drafts of 17 April 2017 reflecting comments made during that period: UMA Core V2.0 revision 21 and OAuth 2.0 Resource Registration revision 08. Here is a detailed swimlane diagram that dynamically tracks the drafts, and a high-level swimlane diagram that briefly summarizes the UMA2 flow. The 2.0 Grant for OAuth 2.0 Authorization(UMA Grant rev 08) and Federated Authorization for UMA 2.0(FedAuthz rev 08) specs are undergoing a second Public Comment/IPR Review period, from September 28 through November 12. Please see the announcement for details on reporting comments or Necessary Claims.
