Tutorial on Semantic Web Technologies: Properties (cont.)

Properties (cont.)

Properties are also resources…
So properties of properties can be expressed as… RDF properties ;-)
- this twists your mind a bit, but you will get used to it
For example:
- (P rdfs:range C) means:
  1. P is a property
  2. C is a class instance
  3. when using P, the “object” must be an individual in C
- this is an RDF statement with subject P, object C, and property rdfs:range
