Web services is a peer to peer system. The Business Interaction among all services is very important for the future of web services.
I have noticed that IBM uses its WSFL and Microsoft with its XLANG schedule drawing in its Biztalk server. But it seesm they will together develop a new protocol for this field.
Does anyone have seen other solutions for the interaction among services?
For the current WSDL definition, there are still lots missing for the potential interactions.
Like no ''contract' between services that could be combined for the interactions, barabara.....
, which makes it very difficult to construct such an interaction in future.
Bill, do U have some idea? Or in your book something related to this?
Thanks,
Roy

Hi, Roy
It is the five key components (all accepted universally), that is XML plus HTTP plus SOAP plus WSDL plus UDDI, form the web services platform. Other technologies like XLANG, WSFL should reside at higher levels, and not affect the main platform.

Hi, Doug,
I agree with Ur words.
But suppose I want to interconnect 4 web services together, and each should know whic web service it should connect and the data format it needs, then without a 'contract' or rule, it is very hard to be implemented....
There's no quality of service at the lower level...
Do U think so?

Hi, Roy
Yes, I think so. Web services lack such 'contract' you mentioned (just like CPA -Collaborative Partner Agreement- in ebXML).

It is sorta covered in the JavaRanch Style Guide.
