Chair: MatthewGraham

Vice Chair: PaulHarrison

Chair Emeritus: GuyRixon

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.

News

• The Credential Delegation Protocol specification has been promoted to a Proposed Recommendation.
• The VO Web Services Basic Profile specification has been released as a Working Draft.
• The VOSpace 1.1 specification has been released as a Working Draft.

Activities

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

• VOSpace
• Security
• Asynchronous services
• Support interfaces
• Service interoperability

Notes:

• Work-package codes: ASYNC = Asynchronous services; BP = Basic Profile; SEC = Security; VOSI = VO Support Interfaces; VOS = VOSpace
• Basic Profile includes VOSI common interfaces and shares its dates.
• The Parameterized Application contract using UWS covers includes an asynchronous ADQL-service.
• It was decided in the Victoria Interop to split the log-harvesting function from the other parts of VOSI; log harvesting is specialized and is not an interface associated with every VO service.
• VOSpace 1.0 specified isolated, unstructured spaces. VOSpace 1.1 specifies structured, linked spaces. VOSpace 2 specifies a RESTful VOSpace interface.
• VOS:VOSpace 1.0 and SEC:Authentication methods are now IVOA Recommendations.

Mailing lists

• The main mailing list for the group is: grid@ivoa.net and is archived at: http://ivoaops/cgi-bin/twiki/forum/grid/
• There is also a list for discussions of VOSpace-related issues at: vospace@ivoa.net which is archived at http://ivoa.net/forum/vospace/
