** Participants **

David Snelling, Fujitsu
Hiro Kishimooto, Fujitsu
Andreas Savva, Fujitsu
Michel Drescher, Fujitsu
Jay Unger, IBM
Jun Tatemura, NEC (via phone)

* Jun walks the group through the document "Designing a POSIX component in CDL"
  written by Jun and with latest edits from Hiro.

* Hiro asks Jun to correct his edits while walking through the document.
  - The newly added elements "cmp:CodeBase" and "bcp:ArchiveType" are 
    effectively the same as "bcp:Binary".
    * An example in the document is provided how to use these elemeents.

* Andreas asks whether the "cdl:ArchiveTye" element is a global element, or an 
  anonmous sub-element of "cdl:PosixApplication". 

* bcp:PosixApplication is a base type. It is extended to e.g. define
  the BLAST appplication ddescription for a CDDLM system.

* [example XML document] Andreas asks whether the name of a declared file
  system can be a child element instead of being part of the element name 
  itself.
  - Yes, this is possible, as given in a proposal later in this document.

* Andreas asks whether there is a way to define that the value of an element 
  comes from another element in that CDL document, or whether that is out of 
  scope of CDDLM.
  - It is not defined by either CDL language spec or component model spec.
    It should be part of the BasicPosixComponent spec.

* Hiro proposes to remove the Environment Variable concept from CDDLM.
  - Because components can give predefined information that otherwise
    would have to be encoded in Environment Variables.
  - The Environment Variables concept os too general to transport such 
    semantically special information like cdl:Hostname (where the applicaiton
    is to be deployed to).

* The group discusses the Environment Variable cconcept, particularly the 
  possibility that, through CDL, the values of certain environment variables
  can be retrieved from the target deployment system. The group shows 
  consensus that the CDL document needs to carry enviroment variables that
  must be set on the target system so that the configured application can run.

* The group discusses the relationships between "cdl:FileSystem" declarations 
  and the definition of "lazy environment variables". In particular, the group
  is wondering about the exact mechanismms how the operation that provides the
  provisioning of the requested FileSystem feeds back the moint point of that
  file system into the appropriate environment variable

PROPOSAL 1a: Use XPath 2.0 as an interface between the CDL document 
 	     and the CDL components
PROPOSAL 1b: Use xsd:ID/xsd:IDREF to allow relations between elements in
    	     CDL documents

* Proposals 1a and 1b are recommendations for the further development of CDDLM

PROPOSAL 2: Eliminate the EnvironmentVariable concept from the PosixComponent
	    (CDL plugin)

* Proposal 2 is specific to the OGSA EMS scenarios document.

** Action Items **

1) Revise the scenario document (i.e. examples) so that proposal 2 is fulfilled
   (Andreas, Hiro)

2) Feed back proposals 1a and 1b to the CDDLM Working Group, i.e. pass back 
   the minutes to the WG. Ask Michel in case of any questions related to these 
   proposals.
