Hi, Joshua -
Thanks for yor feedback!
There is no intention to exclude service discovery, trading, and
matching. We have been working "top down" and have addressed
Visibility (which enables discovery) but have not yet got to discovery
itself. There are other areas - for example service choreography - where
we know that there is work to to but have not yet been able to do it. We
will extend our work to such areas in the future - and of course will be
happy to work with other groups that may be looking at these
areas.

Dr. Harding,
Your interest in feedback for an SOA ontology is appreciated, but taking
a quick look at the definition of SOA on which it is based, I have to
raise the question why it includes only two of the three legs on which
service-based architecture was developed. The role of service discovery,
trading, and matching is conspicuously absent. Indeed, this makes the
ontology perfectly suitable for modeling any application stovepipe and
fails to explain why efforts at interoperability, in fact at the
information-hiding aspects of services at all, are important.
It would certainly be very interesting to learn whether this omission is
deliberate or represents an intermediate stage of ontology development.
It might also be a good topic for SICoP discussion. There is some
question whether definitions of SOA are currently broadening to the point
where they are not particularly useful any more.

Hello -
The Open Group is developing a formal ontology for SOA, and we have
now reached the stage where we have a draft that we would like to
share with other organizations that are working on SOA, in order to
obtain feedback and comment. We believe that a common ontology for
SOA can be a very valuable resource for everyone to use, and we
therefore wish to receive input from as wide a constituency as
possible.
I think that this will be of interest to the SICoP as well as the
SOACoP, and we would appreciate input from both groups. This call for
input is going to both lists, and we would appreciate comments from
all members of them, either directly to me
(c.harding@xxxxxxxxxxxxx)
or to one or both of the lists. (Comments to both lists will generate
the best debate!)
The current draft is draft 0.6 and is available from our web page at
http://www.opengroup.org/projects/soa-ontology/ together with some
simple example ontologies that import it. Perhaps the best starting
point is the presentation at
http://www.opengroup.org/projects/soa-ontology/doc.tpl?gdid=12153
which I delivered at the recent OMG meeting. This explains the
ontology and how we think it will be used.
We will produce a new draft in January, and will address the comments
in that draft.
All the best for Christmas and the New Year!
Regards,
Chris
