3) CDDLM joint discussion #1 (40 min)
         Follow-up discussion on August 3rd.

(3-1)
>> PROPOSAL 1b: Use xsd:ID/xsd:IDREF to allow relations between elements in
>>              CDL documents
> 
>   - Jun thinks that this is not a good idea because ID must be unique
>     in the document and CDL inheritance may break this guarantee by
>     creating duplicate IDs in the resulting document. CDL has a
>     mechanism based on non-unique ids.
> 
>   AI-0803e: Jun will provide an example of the CDL mechanism and why
>             using ID/IDREF is not a good idea.

(3-2)
>> PROPOSAL 2: Eliminate the EnvironmentVariable concept from the
>>             PosixComponent (CDL plugin)
>> 
>> * Proposal 2 is specific to the OGSA EMS scenarios document.
> 
>   Agreed that this is a reasonable resolution for resolving the
>   problem with the PosixComponent and is sufficient for the EMS
>   Scenarios document.
> 
>   AI-0803f: Jun will update the CDL document to remove the Environment
>             variables

(3-3)
>   - A normative definition of PosixComponent 
>     - At the moment there is no such definition; there are only some
>       examples.
>     - Agreed that a normative definition is necessary and that it is
>       not part of CDL version 1.0. Also it is probably too late to
>       leave it for CDL version 2.0---since it is not scheduled yet.
>      - Tentative agreement that this should be a work item for
>        CDDLM-WG between these two document release
>      - Dejan and Jun with discuss this in the CDDLM-WG and seek
>        approval as a work item after CDL 1.0.

4) CDDLM joint discussion #2 (20 min)
        OGSA-WG and EGA Reference Model WG started to identify
        similarities and differences between current works.
        EGA Ref Model's Dependency Graph and Life Cycle of Grid
        Components looks very relevant to CDDLM-WG's work.

        OGSA-WG will have a GGF18 session on Tuesday 4-5:30pm for this
        discussion.

 > From Aug. 17 call
   AI-0817a: Dave Berry and Jay Unger will approach groups (GIN,
             Globus, etc) that have implemented practical grids and
             start a discussion on how they handle data:
             - how data is treated as a resource that can be scheduled
             - how transfers are modeled
             - how files are advertised
             - how applications find files (query, by knowledge,?)
   AI-0817b: Stephen Davey will do a cut down parameter sweep scenario
             focusing on the JSDL+BES+Data Transfer/Staging service

 > From Aug. 10 call
   AI-0810a: Donal to look into the relation of the EPS and CDL
             (retrieval, update, etc). (Eventually this should probably
             become a separate scenario.)

             using ID/IDREF is not a good idea.
