Aristotle’s response struck a chord;
[...] there isn’t much to describe; there aren’t any methods or signatures thereof to document, since access to resources is uniform and governed by the verbs defined in RFC 2616 (in the case of HTTP, anyway)
Right-o, though it might be helpful to rephrase that last bit as “since access to resources is through the *same* uniform interface”, because that’s the whole point of REST: all services expose the same interface. This is what provides the majority of its loose coupling, and is the principle differentiator from RPC.
So if you’re writing (or generating) contract/interface-level code which can’t late-bind to all resources, everywhere, you’re not doing REST (10 kudos to whomever identifies the specific constraint being violated).
Cut the cord already! RPC is dead. You’re not in Kansas anymore.
