Even that does not suffice. There is simply no way based on URIs(*) alone to tell if two URIs refer to the same thing or not. You can only draw that conclusion from some authoritative source of meta-information. Concretely, if you access two URIs and get the same entity body, that proves nothing; they might be only coincidentally the same. If you access two URIs and get different entity bodies, that proves nothing: they might be the same time-varying resource. (*) I think the plural of "URI" is "URIs" despite 2396, just as I think the plural of "euro" is "euros". -- Schlingt dreifach einen Kreis um dies! || John Cowan <jcowan@reutershealth.com> Schliesst euer Aug vor heiliger Schau, || http://www.reutershealth.com Denn er genoss vom Honig-Tau, || http://www.ccil.org/~cowan Und trank die Milch vom Paradies. -- Coleridge (tr.
