Re: Charter goals
One idea we discussed in the call was (1) to define the JSIM and (2) to
identify other IMs that are needed from a Grid perspective, but to leave
the actual definition of these other IMs either to subsequent new WGs or to
this WG as future work under an extended scope. We may well tackle this in
a sequential way as Dan suggested.
I like this idea because that way, the goals for this WG are relatively
clearly defined, and it also allows for some flexibility to extend the
scope (then again quite clearly) once we have gained more experience in
defining such IMs.
I have one more comment: Tom mentioned OGSA as the driver for IMs, I think
we should reword that to be "the Grid community" or something like that,
because the requirements should be driven by the needs of the grid
community, not by the needs of OGSA.
In order to show that what we are doing has a strong relationship to OGSA,
I think we should mention that in addition to a CIM representation of the
IMs, we would also provide an interface definition of OGSA web services
(i.e. GSDL+XSD) according to a general mapping from CIM to OGSA that is
being defined in one of the OGSA related WGs.

Well, who knows really. Neither of us have much to base our projections
on. Let's take a different approach. The group should first do the
queueing schema. Then if there's time, tackle OGSA. How does that sound?
So when the milestones are laid out they would go:
1. develop JSIM (6 mos. we hope)
2. address CIM/OGSA interactions (6-12 mos. we hope)
This way the group can focus on one thing at a time.
Of course the steering group might still say the charter is too broad,
but that's another matter.
