Hi Nathan I'm not saying you're wrong - but could you explain why it would be a pain for FOAF terms to return 200? Which kinds of application are dereferencing those terms and relying on a 303 response? eg http://xmlns.com/foaf/0.1/Person currently 303s to http://xmlns.com/foaf/spec/ What

Hi Nathan - thanks for clear answer. I see the point and also the argument for using hash URIs with ontologies. In practice how I get round this prob is to preload my triple store with the handful of common ontologies I know I'm going to use, so don't need to deref them as I go along. Cheers

Hugh - I understand your point about different provenance and maintenance issues with linkage vs substantive knowledge, but if you dereference a URI, don't you want to also get the linkage information at that point? Of course you could do that while still keeping the two knowledge bases

Hi Eric Regarding your first point - yes, your two options are equivalent and the second one is neater, so go for that. Regarding linking to external resources, what it seems you want to do is to identify the dc:creator of the book, hence say that the creator is the person whose name was
