RDF Namespace

The official W3C-defined RDF namespace is " http://www.w3.org/1999/02/22-rdf-syntax-ns# ". (The # on the end, which may look pretty funny , is not an error; it's there to help applications create valid XPointers.) All RDF documents must use this namespace. The conventional prefix for this namespace is rdf, so I'll declare that prefix like this:

 <?xml version="1.0" ?>  <rdf:RDF  xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">  .         .         . </rdf:RDF>
