* Aims and Objectives
        - Laurence: What are we trying to achieve?
        - Hiro: Architecture design and interface specification.
        - Ellen: OGSA Arch v1.5 (GFD.80) explains current understanding
                 of what is information services for OGSA. It can be
                 starting line.

        - Laurence: What are the boundaries and constraints? Are we
                    working group or design team?
        - Hiro: It is now a design team under OGSA-WG. Let's carry on
                technical work as a design team for a while. In parallel
                you can write up proposed charter document for formal WG
                formation. OGF21 can be target date to have charter BoF
                if we can have enough progress.
        - No objection against working as a design team.

* Fundamentals
        - Laurence: What is a general architecture? It should be
                    scalable. I propose to use GMA.
        - Chris: We should learn from R-GMA.
        - Agreed to learn from multiple existing works. Looking at
          exiting systems and bring them together.
        - Hiro: Is info-GIN work useful? They taught us at OGF19.
        - Laurence: Yes it is. I was and am involved in info-GIN work.

        - Laurence: What are the building blocks and critical interfaces?
        - Query interface
        - How about data model? If you have same model, it is very easy
          to inter-operate.
        - We can leverage SRM approach. We keep only basic interface
          defined.
        - What sort of queries people makes?
        - It is schema issue.
        - There are different kind of queries.
        - We have many many services.
        - We should query multiple services.

        - Use cases should be specified to justify key services.
        - Gin-INFO work already identify multiple usecases already.

        - Agreed to specify Query interface.
        - Hiro: In addition to query interface, do we need push or
                notification type interface?
        - Yes.

        - Agreed to study info-d, OGSA doc v1.5 , and R-GMA,
          existing implementations as an first step.
        - We may have more capabilities to define grid interface.

* Next call (June 28)
        - AI-0607c: Laurence will write up (a) small chart of what
          this design team will do (plan or schedule) and, (b)
          generic information services architecture in a simple chart.
