---+++++ <a name="Status_AN4"></a><a name="Status_AN4"></a>Status:

   * No errata outstanding
   * Not as many requests for GWS contributions as usual for this interop.
   * Group Membership Service - A third working draft has been published and contents will be presented during the GWS session. The next aspect of GMS that needs work is how to reference users within and between institutes. This will probably be another small GWS document.
   * Science Platforms - Many groups are building science platforms using similar approaches and technologies. Haven't had any proposals or seen opportunities for standardization yet, but the work GWS is doing on authentication and authorization is going to be critical for platform interoperability. The key to standardization will be prototypes.
   * Clients (eg TOPCAT) and services (eg TAP) are looking at using reusable tokens for authorization. This means: 
      * There will probably be a new version of IVOA Single-Sign-On Profile (SSO 2.1) coming soon as we look at using reusable tokens for authorization. It is already mentioned but the wording could be more clear. Also, a few small errors have been spotted.
      * There may be a new version of Credential Delegation Protocol that allows for tokens to be delegated.
      * We'll need to describe the method of obtaining tokens that can be used for some set (a 'realm') of services. This will tie into the User Identiy standard mentioned in the Group Membership Service.
   * VO Support Interfaces (VOSI) best practices endorsed note: Preliminary notes taken by Tom McGlynn but no further progress.

---+++++ <a name="Issues_from_Feb_telecon_need_AN1"></a><a name="Issues_AN1"></a>Issues:

   * XML Schema Versioning - The conflict with the 'version' attribute: Working with Paul Harrison and Markus Demleitner to get an updated version out very soon. Looking at softening the language around how to version instance XML documents so that the standards themselves can choose the attribute to use to indicate the standard version.
