Some servers may need to move these URLs around for one reason or another. So clients should only rely on the URL bindings they made and shouldn't be messing with server URLs. I know we've said that there will be a stable URL for each resource for versioning unaware clients, but I don't think those URLs will be useful, especially to versioning unarare clients because they won't resemble anything meaningful.

Unless anyone objects, I propose to make a pass through the protocol identifying those properties which I believe identify stable hrefs. The value to a client is that it can cache these names with the guarantee that another client cannot MOVE them somewhere else. A server can of course chose (or be forced) to break these bindings, but there's nothing we can do about that. Comments? Cheers, Geoff
