Typed Nodes

• One may want to emphasize that a node is of a specific class
  • i.e., it is part of a possible set of individuals
  • e.g., #Datalines node is an “SVG entity”
• There are separate documents on how to define classes
  • “RDF Vocabulary Description Language”, a.k.a. “RDF Schemas”
  • “Web Ontology Language (OWL)”
  • see later…
• We can use the special RDF property rdf:type:

      <rdf:Description rdf:about="#Datalines">

        <rdf:type 

          rdf:resource="http://.../axsvg-schema.rdf#SVGEntity"/>

          ...

      </rdf:Description/>
