I don't think this is true. In my talk, I showed an example with Rembrandt's "Portrait of the artist at his easel". The RDF assertions I used showed that the resource identified by http://www.artchive.com/rembrandt/artist_at_his_easel.jpg is has the mime type "image/jpeg", and it hangs in the Louvre. I rather suspect that the "Portrait of the artist at his easel" that hangs in the Louvre does not have a mime type, but the "Portrait of the artist at his easel" found on http://www.artchive.com/ does. These are two quite different things. When we mix up the map and the territory, we wind up creating silly worlds in which an oil painting has a mime type. This is an important issue for distributed authoring of RDF: how do people know whether they are making assertions about the same thing? I wish I hadn't been in such a hurry on Friday, Walter. We could have had a long and pleasant breakfast discussing these things. Jonathan
