Lot's of interesting questions in here, so I'll wade in on a basic one.

This isn't a question that the web architecture can answer. This is a question of what the publishers of those URI's say they mean to denote by those URIs, or alternatively, what a community of users agrees these URIs shall denote. Arguably, I'll offer, the second matters more, web architecture pronouncements notwithstanding. > Question 3: Depending on the answer to question 1, is it correct to > use owl:sameAs [6] to state that http://www.w3.org/People/Berners- > Lee/card#i and http://dbpedia.org/resource/Tim_Berners-Lee refer to > the same thing as it is done in Tim's profile. It is only correct to say this if http://dbpedia.org/resource/ Tim_Berners-Lee is intended by the authors of dbpedia to denote TimBl the person, as http://www.w3.org/People/Berners-Lee/card#i is said my Tim to denote himself, this last which I believe. Alternatively, you can hold each set of RDF statements suspect, along the lines of "if I believe TimBL, and that this resource is an accurate reflection of his views, then I believe http://dbpedia.org/resource/Tim_Berners-Lee is sameas http://www.w3.org/People/Berners-Lee/card#i. However, this modal statement goes outside what can be said with RDF alone (or OWL alone). In other words, you can only answer these questions, at base, by asking what was intended by the authors of the URIs, or by having a theory that discounts their inten Based on that, you may find that the implementation of what happens when you do an HTTP GET against these URIs either does or does not conform to the published standards for what should happen in either case, and/or decide whether you think the standards are adequate or not for communicating what is necessary for some agent to use productively.
