But is there a way to future-proof the system? Say there isn't an identifying URI for authors, so I put 'dc:creator="Arthur Conan Doyle"' all over the place. Six months from now, someone creates Biographical RDF and defines URIs for historical figures, so Conan Doyle can now be referenced by a URI. Should software look at dc:creator and try to guess if its value looks like a URI, or is the only choice to issue version 2.0 of the model and try to upgrade all the 1.0 RDF files? > <rdf:Description rdf:about="http://..." > rev:date="1999-04-14" rev:author="A.M. Kuchling" > rev:item="book1" rev:item="book2"/> That's legal RDF? (If rewritten to avoid the duplicate XML attribute, of course.) Why were Bags introduced at all, then? Sequences obviously are needed in order to preserve order, but Bags don't seem to add anything if property values can be specified multiple times. (I'll read your articles over the weekend and follow up with any further questions. Thanks for pointing them out!) --amk (www.amk.ca) LADY MACBETH: Out, damned spot! out, I say! -- _Macbeth_, V, i
