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

MessageWhy, that's simple.  Anything is on the web if it has a URI that
responds to an HTTP GET.  POST requests are not *on the web* per se.  Tis
true.  If you traverse a link to a form, then post the form, the result
isn't "on the web".  SOAP services using just POST aren't "on the web".
That's what TAG issue #7 was ALL about.

But "on the web" isn't an important issue and is a red herring.  As Martin
points out, "on the web" probably ought to be dropped from any such
definition.

Cheers,
Dave

    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?
