[ogsa-bes-wg] Discussion on resource models in GGF14

[Fred Maciel]

Hi,

     Apparently we won't have a teleconference tomorrow, so I'm sending this
request for a joint sesson in GGF14 to the mailing list.
     We were discussing the about having joint sessions in GGF14 between
OGSA-BES-WG and the OGSA Resource Management design team to discuss resource
modeling for the container. In particular, it's time to discuss our first
results on a small subset of CIM that is suitable for BES (see my previous
e-mail, copied below, and the attached file).
     Given that the RM session on the 28th (Tuesday) clashes with the
EMS-RSS-UCWG session, and I won't be in GGF on the 30th due to the WSDM F2F,
we have two options on the 29th (Wednesday):

- 7:30 - 9:00: AM OGSA RM design team session
- 4:00 - 5:30: PM OGSA-BES session

     When you start planning the OGSA-BES agenda for GGF14, please schedule
a joint session.

Hi,

      We decided in the F2F in London to use JSDL as a set of properties for
BES, and some people decided to look into CIM as a possibility. The initial
results of this work are in the attached spreadsheet. The three columns on
the left are the JSDL elements, and the following two ones are the
corresponding CIM classes and properties. (BTW, there seem to be several
glitches on the GGF mailing lists, and apparently Andrea's e-mails which had
this spreadsheet didn't reach this mailing list).
     Our conclusion for now is that by using a number of CIM classes and
associations, with some extensions, we can represent what is in JSDL, both
for the status of the container and activities and also the requirements
submitted as a JSDL document. So, this CIM subset is suitable to use as a
model for BES. (Notice that I'm talking about the model semantics only -- 
how you represent this on Web services is a different issue, which we will
tackle later).
     The discussions we had the two RM design team teleconferences were
quite interesting, with for instance discussions on how the JSDL entities
map to the container and activities. Working on the resource model will help
clarifying the semantics of the BES entities.
     Andrew, please add a discussion on the model to the next OGSA-BES
teleconference (in case we are having one).
