---+ Agenda for GWS-WG sessions at Beijing Interop meeting

---++ Session 1: VOSpace 1.x

The VOSpace 1.x series are the SOAP-based VOSpace standards. VOSpace 1.0, which is at the WD stage, is for the flat, isolated space. VOSpace 1.1, for which the specification is under discussion by an experts group, adds container (directory) hierarchies and
links between spaces; it approximates AstroGrid MySpace in function.

Three presentations (15 min each):

   * Implementing VOSpace 1.x, what works and what don't  - DaveMorris 
   * ESO lessons learned from implementing VOSpace 1.0 with NGAS backend - PaulHarrison
   * Implementing VOSpace 1.0 without Axis - MatthewGraham

Followed by discussion on changes required for 1.1.

   * [[http://ivoa.net/forum/vospace/index.htm][VOSpace mailing list]]

Objective: decide where we are going with VOSpace 1.1

---++ Session 2: RESTful services

This session covers services to the REST paradigm, including particularly:

   * UWS;
   * extensions to DAL services for data staging;
   * RESTful versions of VOSpace (which may appear as the VOSpace 2.x series).

Email discussions suggest that just about everybody prefers REST to SOAP and that all new
standards for IVOA should be RESTful rather than SOAPy. If you disagree, then this is your
best chance to put your point of view.

Talks:

   * REST paradigm compared with SOAP - NormanGray
   * REST vs WS-* - MatthewGraham
   * Rest binding to UWS (including demonstration) - GuyRixon
   * Data staging techniques for DAL - DougTody
   * VOSpace-2.x, REST and WebDAV - PaulHarrison

We shall be tight for time in this session, so please make your talks brief enough to allow
time for discussion.

Objective: shared understanding of what REST means and how we can exploit it.
But specifically, I want to find out how well UWS v0.3 fits with other, planned IVOA standards and to decide who will be the authors for the later, more-refined drafts of UWS.

---++ Session 3: SSO and VOSI

Talks:

   * The NVO Identity Services and Suppport for Secure Portals - RayPlante
   * Reference implementations for SSO components - GuyRixon

Followed by a short open forum for any attendees to speak on their security work
(no slides needed). Hopefully, we can get through the security part in the first
half of the session.

Second half of session: what to do with VOSI. This naturally follows on from the
discussions in Registry-WG about how to harvest rich metadata. If those discussions
reach consensus, then we should be able to decide how VOSI should come out. If
there is no consensus then we can't say anything sensible about VOSI and we can finish
early.

   * [[http://www.ivoa.net/internal/IVOA/IvoaGridAndWebServices/VOSupportInterfacesMandatory-0.26.pdf][V0.26 of VOSI specification]]

Objective: plans for V1.0 WD of VOSI, dependent on outcomes in Registry-WG.
