Hello Titto,

I have no problem with this at all and alot of work has been done in using RDF to express WSDL.

WSDL at the moment is supported by several SOAP solutions (Sun's Java Web Services, MS SOAP, .NET) and being actively progressed by W3C - i think. This was the natural choice for us at this stage. However, the work you mentioned looks very exciting and I imagine it to be part of the discussion to get an 'agreed' Web Services architecture up and running.

As an exercise I will try and build a SemanticWebServer service description using the DAML services stuff. Thanks for the pointer.

cheers,

graham

Hello,

what about using RDF itself to define the interface of your RDF service?

There are a number of ways of doing it.

Two examples are NEOOM http://www.nesstar.org/sdk/neoom.pdf and DAML
Services http://www.daml.org/services/.
