First, sorry for the typo - I meant to refer to the SOAP data model, not
the SOAP object model.  My fingers automatically type "object" before
"model" these days.

In general terms, we should allow people the flexibility of different
starting points - MOF, RDF, SOAP data model - with interoperability at the
end point of SOAP and Web Services.  To this end, there are two pieces that
I'm currently thinking of looking at:
- Can XMI serialization of MOF and UML models and instances conform to the
SOAP rules for serialization?
- Can we provide a mapping between MOF/UML models and the SOAP data model,
analogous to what we now have between models and XML schema?

I'm interested in comments on this.  In fact, OMG members in this group are
welcome to actively participate by joining the XMI mailing list, or by
requesting to be on the XMI Task Force.  Email me if you'd like more

I would just like to point out that SOAP doesn't have an Object Model. But
coming to SOAP/Web Services from MOF is a Good Thing, IMHO.

Barbara, can you explain some more please? Do you mean that SOAP based
systems would take part in the MDA approach and as such can be described
by an XMI serialization? Or do you mean that you intend to take the SOAP
'type system' and define its expression in XMI? Or do you mean that you
intend to take XMI and define its serialization in SOAP encoding? Can you
post the text of the issue that you plan to open?

Lots of questions, but would appreciate the answers, since I've a keen
interest in using XMI encoding in SOAP messages.
