[MOBY-dev] Regarding XML conversion

[Paul Gordon]

Hi Yogaraj,

This is, unfortunately, a near-impossible task because although you can 
take data from one service and pass it to another, you have no idea 
whether the xsd:String output in the WSDL of one service is semantically 
the same as the xsd:String input to another service.  Web services deal 
with syntax (structure) only, whereas you need semantic (meaning) 
compatibility for real interoperability.  That's why MOBY has a central 
ontology, and we are calling them Semantic Web Services (though not 
really as the W3C uses the term).  One approach is to retrofit services 
to a semantic standard such as MOBY.  It's a LOT of work to even 
semi-automate this (I am doing this now).   If you want to do this 
generically for  any WSDL, the best I can suggest is to restrict 
yourself to some easily recognizable data formats that you can detect as 
data comes out of services, such as strings encoding URLs or e-mail 
addresses.  That way you can seamlessly and fairly confidently make 
services that output and consume URLs compatible.  Trying to make all 
services compatible, I believe, is a sisyphean task.

Regards,

Paul
