Sorry to repeat myself:
There is already a simple protocol that requires no prenegotiation. It's
called Simple Object Access Protocol. All the MSG team has to do is throw
out all the ebXML add-ons and you have SOAP and we can all go home.
Similarly, if what you want is for some Web service to dictate the IT terms
and conditions to anyone who wants to do business with it, all you need is
WSDL. If that's the world you want, again, no re-inventing is needed.
In other words, there already exists what is needed for SMEs. We could
subset ebXML down to the equivalent of SOAP/WSDL or we could decide that
our space is really B2B.
Regards,
Marty

RE: [ebxml-msg] Messaging Spec v1.092

You said ...
>>>MWS:� See my first comment above.� You cannot avoid the runtime database
unless you think that you can legislate a single software and middleware
configuration that everyone is required to use on pain of ...<<<
I agree you cannot legislate, but you should be able to define default
parameters for sending a message reliably, for example, which does not
require prior negotiation.
What we need to do, is make a decision early-on in the development of the
next spec on whether we are going to develop:
1. A Negotiation Protocol, which leads to the agreement of a CPA, which
then results in the exchange of messages according to the ebMS spec (which
is what I think you are suggesting Marty), or
2. A lighter weight spec which allows messages to be sent without prior
negotiation but which can reference a negotiated agreement if it exists
(which is what I am suggesting).
Currently I think there are some who think the first approach is overkill
and won't be used by SMEs or the Web Services community, and some who think
the second approach won't work. Either a way decision on the way forward
has to be made.
