I think this is something we have been working on (and will probably keep working on). It is well established work so the artifact can be closed.

From the 2003/11/06 teleconf:

  - Still a hot topic. It is being talked about in the GFSC. 
  - OGSA-WG isn't trying to dictate anything to other groups; just to
    have better communication with them. It's necessary since we are
    trying to define an architecture.

  Action: Co-chairs + AG + DS to draft up a memo explaining why the
          OGSA-WG finds it necessary to think such things.

since CMM use cases looked like OGSI use case idea for OGSA.
  But the OGSA members had a doubt on this ( for eg: configuration).
 Fred  will talk further about this issue in the CMM group.

Fred also posted some additional docs but no use case yet.

Next steps are being discussed. It has to do with the interdependency between services.
