FACT: OGSA is predicated on Web services best practices, tooling, and
FACT: Not everyone is enamored with WSRF, meaning that WSRF is unlikely to
be "just there" in the tooling and infrastructure anytime soon.
OGSA-WG can choose to stick its collective head in the sand and hope that
this issue goes away, or it can attempt to address this problem head-on and
come up with a solution. This is essentially what this BOF is about.
I'll point out that I'll be happy either way: If we decide that it does not
make sense to continue this non-WSRF profile, then my group has already
produced a pretty high-quality implementation of WSRF on the .NET framework
that we'll continue to refine and support. If we as a group decide to move
forward with this non-WSRF profile, then we already have some results with
an implementation of WS-Transfer we wrote and we'll hopefully have a larger
community working on this effort.
Finally, to twist things around, if this effort is squashed solely because
WSRF is "first to market", then... to quote Fred: " Who wins then? I have a
few guesses, but I am not stupid enough to list them in public forum."
Again, to stress, I personally just want convergence. If the group decides
that OGSA would better converge by focusing on WSRF, then I will happily
support this decision (in fact, my research group's lives would probably be
easier!) I just want this decision to be made based on realistic and
technically sound evidence, not religion.
