A few people, myself and Paul Prescod included, have independently suggested a URL scheme just for naming. It would take the same format as an HTTP URL so it would leverage off the DNS, but its scheme would clearly indicate it is a name. So a namespace for FOP stuff might be hname://xml.apache.org/fop/ Some have argued that there is no practical difference between a document that describes the thing and the thing itself. I can buy this for things like specifications (where the document doesn't just describe, but defines). But for some things, like people, that are being assigned HTTP URLs for use with RDF, I think you bump into problems if you also put a document at that URL describing the thing. Why? Because assertions about the thing might not hold for the document about the thing. The Dublin Core "Creator" for the resource would probably be different depending on whether the resource was the person or the document describing the person. So there is a need to distinguish. Of course, there is the whole "what the name of the song is called vs what the song is called vs what name of the song is vs what the song is" :-) James Tauber xml-dev: A list for W3C XML Developers.
