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
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
simple example ontologies that import it. Perhaps the best starting
point is the presentation at
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
