I have the folowing RDF Schema
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix mynamespace: <http://example.com/example#>.
example:Car
a rdfs:Class .
example:Wheel
a rdfs:Class .
example:size
a rdf:Property;
rdfs:domain example:Wheel .
Now I want to say that the wheel is a property of the car, but also that it is a class. How can I do that?
