RE: Nailing down the definition of "Web services" and the scope o fWS A for the document

An information object is 'on the web' if it has a URI.

I think that interacting via standard protocols on the Web might be a bit better.  Would CORBA still be in the stew then?

In an earlier mail Mike suggested:
"A Web service is an interface to an executable software agent that is designed to be used by another software agent. A Web service is identified by a URI, and has a definition in a language sufficient to describe the interface to developers of client agents. A software agent interacts with a Web service in the manner prescribed by the formal definition, using standard protocols."

Using this defintion, CORBA objects are web services! They can have URIs (added about three years ago), they are defined using IDL which is sufficient to for developing client agents and they interact using standard protocols (iiop).

I am not for one minute suggesting that CORBA objecst should be in the set, but without a better definition they will be and i'm not sure what use that is.

Anyone remember business objects? Nice marketing term but no one could provide a techical defnition whereby if one were given something you can tell whether it was one or not. I'd hate to see web services go down this route.

Martin.

WSA-compliant is way too strong a term IMO. Why can't we just call it a Web Service?
