Binding RDF to an XML Resource

• You can use the rdf:about as a URI for external resources
• You can add RDF to XML directly (in its own namespace).
  • Eg, in SVG:

        <svg ...>

          ...

          <metadata>

            <rdf:RDF xmlns:rdf="http://../rdf-syntax-ns#">

              ...

            </rdf:RDF>

          </metadata>

          ...

        </svg>

• An encoding format is also defined for (X)HTML...
• ... or you can use the <link> element
• Some details are still subject of discussions
  • current RDF/XML encoding is not DTD friendly
  • XML Schemas are o.k., but they are heavier
  • discussions are ongoing for DTD-bound applications
