Alan - I agree with not creating new URIs unnecessarily, but if you are setting up your own knowledge base on a topic and want to add new information about those resources, and you want the user to be able to dereference the resource URI to find that information, then it seems to me that you pretty quickly get to the point where you have a decent reason to create your own URIs. This will of course lead over time to a lot of owl:sameAs links all over the place, but I think we just have to deal with that. Without wanting to re-open an old thread, I broadly agree with Richard Cyganiak's viewpoint in http://lists.w3.org/Archives/Public/public-lod/2009Feb/0010.html Cheers

Willy nilly inventing URIs and entities when there are perfectly good ones in existence is not "cool" from a semweb point of view, and unnecessary use of sameAs is both burdensome and likely to lead to gross errors, as I have pointed out in my previous emails. -Alan
