Minutes of the 3rd telecon
The 3rd CGS-WG telecon was held this morning (Pacific time). Attendees

Eric Woo (IBM Yorktown)
Peter Gietz (DAASI)
We reviewed the meetings at GGF6 in Chicago last week. There were 2 CGS-WG
sessions and 1 joint session with DAMED/NM/CGS. The latter session was to
figure out if/how these groups should interact. The DAMED group is shutting
down (finished) and the NM group will work on a schema that might later be
fed to CGS for translation to CIM.
The first CGS-WG session reviewed the group charter and goals, and a brief
intro to CIM Modeling was presented by Ellen Stokes of IBM. The second
CGS-WG session reviewed the JSIM document, specifically the UML diagram.
Various issues were raised that will be discussed on the mailing list.
During today's call, we again discussed the issue of producing an XML
representation of the MOF we deliver. Peter and Jenny suggested that it was
a "contract" in our charter. Andreas suggested we wait for and make use of
work that IBM is doing to algorithmically transform MOF into XSD. Larry
said that even with an algorithm to do the translation, producing an XSD
that is relevant and useful to the OGSA efforts will be a lot of work. This
issue will be discussed on the mail list.
Peter asked how decisions are made in a WG. Jenny said that any decisions
made during meetings or calls should be reiterated to the mail list. We
should establish a policy that decisions sent to the mail list have a 2 week
deadline for responses. If no significant objections are raised during this
period, then the decision will stand. (Of course it can always be changed
The issue of job dependencies/workflow was raised during the second CSG-WG
session at GGF6. During this call, the sense was that we don't want to dive
into this problem as part of this WG right now. This issue will be raised
to the mail list.
The JSIM UML shows the BatchQueue attached to the OperatingSystem. In grid
environments, the job queue belongs to a job scheduler/execution system, not
directly to the OS. There can be multiple schedulers, and one scheduler can
have multiple queues. Andreas, Viktor and Ellen will work on an update to
the UML that will be posted to the mail list in advance of the next call.
There was some discussion about the "clarity" of the UML. Andreas advocated
use cases. Peter asked that the UML be made as clear as possible. Andreas
stated that UML by itself is not a complete story.
The next CGS-WG call will be in two weeks (5 NOV). The agenda will roughly
be to review discussions and decisions made on the mail list over the next
two weeks, and to review the updated UML that will be posted.
Peter proposed that Larry become the official CGS-WG Secretary, and there
was no objection. Peter will update the charter accordingly.
