In fact, there is a variety of stuff at the end of W3C namespace URIs. A few examples: XHTML - http://www.w3.org/1999/xhtml - resolves to HTML page RDF - http://www.w3.org/1999/02/22-rdf-syntax-ns# - resolves to RDFS P3P - http://www.w3.org/2001/09/P3Pv1 - resolves to XML schema SMIL - http://www.w3.org/2001/SMIL20/ - resolves to HTML page :-( So, I'll ask the same question I asked a few days back... if I make an RDF statement about http://www.w3.org/2001/SMIL20/, am I making a statement about the abstract SMIL namespace or am I making a statement about the HTML page that the uri resolves to? The only answer I got last time suggested that I'd be making a statement about the abstract concept. If this is the accepted view, then I still do not underdstand how I make a statement about the HTML page that uri resolves to. Presumably, the dc:creator of the abstract namespace is not the dc:creator of the HTML page at the namespace uri - so there are valid reasons for wanting to make RDF statements about both. As far as I can tell, http://www.w3.org/2001/SMIL20/ is the only uri for that HTML page so I don't see how else I can make a statement about it. This feels like a very fundamental and simple question to me!
