Hi Xuan - I agree with Steve's comments and I would like to reiterate three points. First, as background, an OWL-S service specification must have some kind of grounding to be usable. An OWL-S profile and process model provide a semantic model, but they are considered to be "abstract" in precisely the sense that they don't provide communication details. A grounding is intended to provide those details. Second, we (the OWL-S folks) have said all along that the WSDL grounding is just one of many possibilities for grounding an OWL-S service. (Actually, at least one other grounding approach has been developed.) Third, it's my understanding that WSDL allows for specification of other protocols besides SOAP. At least that was true in WSDL 1.1. I haven't looked closely at WSDL 2 in this regard, but I sure hope it is still the case.
