RE: [wsbpel] Liaison Activity - WAS: [wsbpel] CEFACT Liaison Review

["Fletcher, Tony" <Tony.Fletcher@choreology.com>]

Dear Sid, David and others,

Your distinction between liaison and observer seems very reasonable to
me, though probably not the only one.

Further clarification:

WSCI is an input to the W3C WS-Choreography group.  While it is
undoubtedly a useful input document the groups' current thinking is that
its output choreography description language is likely to be different
and not directly traceable back to WSCI.  However, the general point you
make is that we will benefit from a liaison with this group and I agree
with that.  We do in fact already have that as an active liaison and
both Steve (Ross-Talbot) and Martin (Chapman), the co-chairs of the
WS-Choreography group were present at the F2F last week and Martin gave
a liaison report on the Friday morning.

I have always anticipated that we would need a separate liaison with the
BPSS work and I know that Monica (Martin) has been 'in the frame' to be
our liaison person, but the future of the BPSS has been 'uncertain' (at
least in the public view) for sometime as things in UN/CEFACT with
regard to BPSS could be described as 'rocky'.  This uncertainty was
(mainly) resolved later on last Friday with the announcement of the
creation of a new OASIS group in the ebXML family to take BPSS forward.
I would support a liaison to this new OASIS TC.

Given the wealth of experience in business matters that UN/CEFACT
represents I urge that we continue to have a liaison in that direction
as well.

I do not see any reason to limit the liaisons at present.

Best Regards     Tony

As of today, there are 2 other general-purpose business process 
definition/choreography
languages under consideration in a standards body:  BPSS in OASIS and
WSCI 
in W3C.  For
the near term, these and the associated underlying standards on which
each 
is dependant
should be part of the liaison activity.  Everything else is
non-normative 
and perhaps
out of scope for this group.

As for the difference between Liaison and Observer, I would say that in
the 
former,
there is a great deal more cross-pollination and active engagement (in
the 
form of
normative bi-directional presentations and mutual consideration,
specific 
approaches,
etc.).  The purpose of this activity, in many cases, is the avoidance of

the invention
of the perennial wheel.

While in the later, there is, at best, a one-way channel for allowing 
information
gathering by one party.  No feedback mechanism is deemed necessary.
