Vice Chair Emeritus: PaulHarrison, AndreasWicenec, BrianMajor

Rationale

The aim of the GWS WG is to define the use of Grid technologies and web services within the VO context and to investigate, specify, and implement required standards in this area. This group was formed from a merger of the Web Services group and the Grid group, ordered at the IAU General Assembly in 2003.

Mailing list

• The main mailing list for the group is: grid@ivoa.net
  • Register: http://mail.ivoa.net/mailman/listinfo/grid
  • Archive: http://mail.ivoa.net/pipermail/grid/

Activities

Each of the main areas of concern of this group has its own page:

• VOSpace
• Security
• Asynchronous services (UWS)
• Support interfaces
• Service interoperability

Current Roadmap

During the interop in Trieste, the Grid and Web Services working group came to an agreement to support a standard means of authorization through group membership. Such a standard will enable interoperable authorization among IVOA services. It is to be determined whether a note documenting the endorsement and use of an external standard, or an IVOA standard itself is the best way to incorporate group authorization into the IVOA. A draft of such a proposal will be presented in Shanghai.

A new VOSpace 2.1 Working Draft to be ready before Shanghai. As per the discussions in the first GWS Trieste session, it will include mention of the Public Share Protocol. This protocol may be use to obtain long-lived URLs for publishing papers and DOIs.

"Code to data" was a topic of much discussion in Trieste. The GWS working group will pair with the DAL working group and the Knowledge Discover interest group to work on a simple IVOA approach on processing data using client submitted code.

Grid and Web Services Standards statuses:

• The SSO 2.0 final Proposed Recommendation will go to Exec before Shanghai.
• The VOSI 1.1 final Proposed Recommendation will go to Exec before Shanghai.

We would like to create an IVOA note with examples on how to use the various authMethods described in the SSO 2.0 specification.

We would like to create an IVOA note on ideas and best practices for implementing VOSpace.
