Marty:
Thanks, that makes a lot of sense. And Mark puts it nicely: poetically,
even (-:
Ian.

Hi Ian et. al.,
A very good question! (?can you define the goals of the BOF more
precisely
other than "not WSRF"?) I sent this email in part to hear from
the community
how ?broad? they might like it to be. That is, we?re being flexible.
If
someone wants to talk about one of these specific topics, we will
certainly
try our best to accommodate.
Note that by default I believe the discussions will center around
WS-Transfer, WS-Enumeration, WS-Eventing, et. al. I will talk about
my
team's use of WS-Transfer, WS-Enumeration, and WS-Eventing. I think we?re
in
a very good position to discuss the pros and cons of these specs as
compared
with WSRF (as our project has implemented/used both).
Let me answer the question in a different way. GGF Chair Mark Linesch
said
recently: "Our approach with the OGSA architecture along with
our
collaborative work on OGSA profiles is to: (1) describe 'the most
traveled
paths through the forest' rather than to dictate that there is only
one
path; and (2) to continue to highlight that multiple, overlapping paths
may
not be in the interests of the industry over time"
(http://news.taborcommunications.com/msgget.jsp?mid=403500&xsl=story.xsl)
Simply, we believe that there has been sufficient "hallway
discussions" on
BOTH (1) and (2) that it makes good sense to gather people to discuss
BOTH
of these topics in a realistic and productive way.

Marty, Steven:
It is of course feasible, in principle, to define many different
profiles
for OGSA. E.g., one could build one on WS-Transfer and friends, one
could
build one that uses a different construct than the WS-Addressing EPR
to
address things, one could define one that uses JINI mechanisms, one
could
define one that uses CORBA, one could define one that renames all of
the
current WSRF and WS-Notification calls to be slightly different (oh
wait,
that's the first in the list (-: ), etc.
Given the wide variety of possible alternative profiles, it would be
helpful
for those like me who are considering attending the BOF to know what
more
specifically what the goal of this work is going to be. The name
doesn't
provide any information, other than to imply, perhaps, that the
interfaces
on which the WSRF profile builds are not in some manner
"minimal" and/or
"simple." I.e., can you define the goals of the BOF more
precisely other
than "not WSRF"?

Folks,
There have been a number of informal conversations lately about the
feasibility/value/implications of a possible non-WSRF-based profile
for
OGSA.
To bring all interested parties together at the same time, a BOF has
been
scheduled for Tuesday June 28 noon-1:30 (unfortunately at the same time
as
the EGA session, but there were no good times available). The agenda
is
still being finalized, but we expect to broadly discuss the pros/cons
of
such an effort, and, if the BOF attendees decide that such an effort
would
be valuable, produce a concrete plan for the formation of a Working
Group.
Here is the information that Steven Newhouse provided for the GGF
organizers:
"A BOF meeting to discuss the creation of a WG to define an OGSA
Basic
Profile that builds upon a minimal set of simple web services. The output
of
the group would be a document, similar in nature to the OGSA WSRF
Basic
Profile that would allow OGSA services to be rendered using an
alternative
set of WS specifications."
I hope you can attend this (hopefully) productive and constructive
session!
