  • I am confused

    REST was sold to us because WS-* was too complex and all you would need was to expand the resource space or use hypermedia as you see fit. In particular, people like Steve Vinoski or Bill Burke kept telling us that because the interface to resources was "Uniform" you would be building non-breakable distributed application.

    Now, you are telling us that because "RESTful" services can't support namespaces, we have to create a central registry of some kind of contract metadata. You are telling that extensibility is really hard to reach.

    To me, HTTP headers sound like an obscure non RESTful kludge for dealing with extensions.

    Looks like you could have done all this work with WS-* in a fraction of the time. Am I mistaken?
