OWL-S provided its grounding on standard OWL and WSDL.
WSML delivered compliancy with WSDL later.
Personally I do not consider SAWSDL of high value towards
realizing the original vision of the *semantic* Web but to industry
being in the stage of serioulsy adopting WSDL and BPEL in
internal SOAs for their application landscapes -  and that's actually
quite a lot, but literally is it.
On the other hand, what overall benefit does the view on SWS with SAWSDL 
as its **standard** promise more than, for example, statistical Web
service coordination exploiting mixed approximate reasoning means
for your application as known eg from the domain of P2P IR and advanced
XML schema matching? This discussion is indeed vivid in the relevant 
domain of IR for quite some time (we tried for example to marry both
perspectives in hybrid service matchmakers owls-mx and wsmo-mx).

Anyway, my question rather was what is supposed to come next for
R&D on SEMANTIC web services from the point of view of the ** W3C **.

Is there any ** explanation ** attached to the proposed recommendation
of SAWSDL by the W3C (similar to those for the submissions
they received in 2005)? It would be highly interesting to read it.

And, second, where to discuss - as members of the SWS research
comunity - the implications of the upcoming decision.
Personally, I would prefer the options 2) and 3) suggested by Bijan.

in fact, i could ask natasha and karl whether we might
reserve a slot for it at iswc07. and if the W3C is going
to announce a joint meeting on this subject organized by themselves
soon, or whether they would support a panel on that in busan - that 
would be just great and help a lot to know :-)

cordial regards, matthias
