XML transfer encoding

RDF Model&Syntax specification specifies many syntaxes for the same data model

1. Standard - presented earlier
2. Elements as attributes and element content as attribute content

     <Description about="http://www.foo.bar/video.mpg"
                  dc:Author="Janne Saarela"
                  xmlns:dc="http://purl.org/DC/RDF/" />

   -> No exposed element content (useful when embedding to HTML)
3. typedNodes (An element has automatically a type without explicit 'type' predicate)
