- To emphasize that a node is of a specific class
- i.e., it is part of a possible set of individuals
- e.g.,
#Datalinesnode is an “SVG entity”
- There is a separate document on how to define classes
- “RDF Vocabulary Description Language”, a.k.a. “RDF Schemas”
- see later in this tutorial
- 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>
