RE: The stack diagram (was RE: Discussion topic for tomorrow'scall)

I am not sure we ever said SOAP was a requirement, although personally it seems to me to be a kind of minimum requirement for what's typically thought of as a "web service" -- it all started with the SOAP spec back in late '99, after all.

Our formal Web services definitions have tended to be more generic, along the lines of "XML over HTTP"

AHA!!  Hugo seems to be saying that you can have a Web service that just
uses HTTP without SOAP, as I documented in the note I just sent a few
minutes ago.  So we are NOT saying that Web services MUST use SOAP?

I think that it all comes down to knowing how many diagrams we need to
represent our space, so that each diagram is reasonnably simple and
understandable.

We need to address the fact that HTTP without SOAP may be used to do
some requests, such as with the SOAP 1.2 HTTP GET binding.

This is why I am worried about showing HTTP in the transport box without
any link to the message box. I think that I could live with this diagram
if there was some text accompanying it talking about that.

And in this case we should also add some explanation about why HTTP is
in a box called transport, otherwise I foresee comments about that.

Regards,

Hugo
