Instead of version being a resource with a URI, these simply identify a resource at a *point in time*. The version is a "coordinate of a resource." Last-Modified and ETag use coordinate as a condition for a request: They identify *representations* of the resource, not separate resources -- although they could also be available as separate resources (and sometimes are). As Mike said, this is not either/or. Cheers, -- Mark Nottingham https://www.mnot.net/
