If you take the IETF view of URIs then they can be - if you provide the URI resolver mechanism. Going back to a thread of a couple of weeks ago - that's the II resolution query for URIs. Using II queries, you could have many things being specified the same - such as urn:isbn:074559922394 and http://www.amazon.com/booksearch?isbn=074559922394 *providing* your resolver was set up to handle this (ie amazon would probably provide the authoritative URI resolver for that instance). The handling of RDF URIs obviously was a cause for debate last time around in this thread. Whether they should diverge from the "standardised" view of URIs is open to another flamewar (they seem to be the only case in all of XML land that seem to not follow the IETF rules)..... -- Justin Couch http://www.vlc.com.au/~justin/ Freelance Java Consultant http://www.yumetech.com/ Author, Java 3D FAQ Maintainer http://www.j3d.org/ ------------------------------------------------------------------- "Humanism is dead.
