(this is an initial draft so scope and focus are still fairly open. Please add comments to the Talk: VAG if you have slightly different viewpoints so we can try to converge on a common view. This discussion could also expose other similar VAG that are needed in this area --Zah 15:20, 23 October 2007 (PDT) )


The Core Grid Services, Protocols and structure VAG focuses on the grid and web services, the protocols and the overall structure of the AWG's work. Particular attention is focused on creating designs and architecture which is consistent with the nature and approaches of the World Wide Web.

See the Architecture Working Group and the Viewpoint Advocacy Groups for more information.

List of concerns addressed by this viewpoint

  • Modeling services via REST
  • Best practices in Web Services Design
  • Appropriate uses of C-hhtp, Escrow, and capabilities
  • How to handle continuing streams of events (pub/sub) in the architecture
  • The overall shape of the design, including concepts such as domains, proxies and computational boundaries.

Areas not addressed by this viewpoint

  • Implementation of core components behind the architectural boundaries. We will examine such items only to the extent that they drive our core concerns.
  • Underlying representations of 3d objects. We may examine efficient encodings, but we will defer 3d issues to the Geometry and Physics VAG

Use Cases

See the Architecture Working Group Glossary and usecase templates for more information on creating usecases. One liners are fine (and better than nothing) but more detail will result in a better understanding and a better architecture.

  • Category 1
    • Use case a
    • Use case b
  • Category 2
    • use case c
    • use case d

Related JIRA Issues

The following JIRA issues are known problems that this VAG would like to see resolved in any future architecture. The purpose of this list it to avoid problems that exist in the curent architecture. The more typical JIRAs that are more short term in nature or can be resolved by simple code or design change should not be listed here.

  • JIRA1
  • JIRA2
