   RE: [xml-dev] Partyin' like it's 1999

[ Lists Home | Date Index | Thread Index ]

Actually, RDF does *not* use namespaces like you are thinking.  RDF has the concept of using a prefix as “convenient shorthand” for a URI, but it is done in a way that is incompatible with namespaces in XML.  In RDF, the fully-qualified term is evaluated by concatenating the URI and term, where in xml namespaces the qname is never considered to be produced by concatenation.  This subtle difference can be incredibly confusing for people.

If Namespaces are in fact a disaster, then why is widely used in any XML Vocabulary, like RDF or OWL?


If these are a disaster, then the basis of the Semantic Web -OWL, RDF-, and many other systems are in big trouble...


All the best,
