It was noted in the minutes of the TAG conference call that there was a log of discussion but no counter-proposals. So here's one. I suggest that the appropriate W3C TAG policy should focus on the value: Designs that use URIs as accessors for resources and URI references as accessors for resource components are better than those that don't. and that the following guidelines could apply: HTTP GET should be "safe" (because there are systems and operations that rely on it being so) When designing an interface to a safe operation, there are significant advantages to using GET-able URLs (e.g., with query strings). There are some disadvantages to using GET with URLs in HTTP, e.g., when the addressing information is is large, difficult to encode, private or best kept secret. Whether or not GET with HTTP is used for the initial access, supplying a URI for subsequent access to the _same_ information, e.g., using Content-Location, is useful. I'm not opposed to URLs or linking, just to a finding that jumps from a value ("URL linking is good") to a policy ("safe actions should use GET") without sufficient consideration of the drawbacks or of the alternatives that might accomplish the same goal without them.
