RE: Data Access WG questions about WSDL

Dear All

Where can I get the latest development on WSDL, UDDI, SOAP and XAML.
Moreover, I want to know the latest on the Semantic Web Services.

Also, I would like to get the open research points and issues on web
services and semantic web services

Regards

MAQBOOL

Yes, as written, the spec prevents the above, near as I can tell. It
does so
because *if* you have a binding that uses multipart/form-data as
inputSerialization, then you have to use multipart style for that
binding.
In which case the nice single operation, query, really does become two
separate operations: different styles and different output
serializations.
But then you really need *four* operations:

query1: GET, IRI style, application/sparql-results+xml
query2: GET, IRI style, application/rdf+xml
query3: POST, multipart style, application/sparql-results+xml
query4: POST, multipart style, application/rdf+xml

Wow, now *that's* confusing. And ugly. Really, really ugly.
