From the point of view of process, and socially, this is a curious development. 1. Briefly, The SWBP WG is not the design authority for HTTP URIs, so it not in a position to say MAY about them. It is in a position to take part in the debate. 2. Technically, his is a very far-reaching decision rather than a comment on best practices. 3. As it stands, the SWBPWG resolution does not resolve the TAG issue. The resolution of the issue requires the answering of the questions around it in the context of a consistent architecture for the Web. Clearly the SWBPWG has an architecture in mind. Could the SWBPWG, in proposing an architecture, like to propose an ontology of Web architecture? Could they for example please explain, in their ontology, semantics of an HTTP 200 response? Could the SWBPWG please answer also answer the following: 1. Who was the creator <http://www.w3.org/2005/moby/dick> ? 2. What is the year of creation of <http://www.w3.org/2005/moby/dick> ? 3. Who was the creator <http://www.w3.org/2005/moby/xyz> ? 4. What is the year of creation of <http://www.w3.org/2005/moby/xyz> ? This is not to say that the is issue is simple, or that the present practice does not include that the SWBP describes. It asks for a consistent and worked out alternative. I had the hope, after the face-face meeting at the TP, that the task the group was taking on was to lay out that architecture. Tim BL Unofficially. Not as Director.
