OWL Examples: Classes

• New "sets" can be created using others, eg
  • subclassing:

        <owl:Class rdf:ID="AnimationDescription">

          <rdfs:subClassOf rdf:resource="#SvgEntity"/>

        </owl:Class>

• • set operators:

        <owl:Class rdf:ID="animationTimeControl">

          <owl:unionOf>

            <owl:Class rdf:resource="#AnimatePar"/>

            <owl:Class rdf:resource="#AnimateSeq"/>

          </owl:unionOf>

        </owl:Class>

• Operators include intersectionOf, complementOf
• disjointWith, oneOf, ...
