Properties (cont.)
-
Properties are also resources (named via URI–s)…
-
So properties of properties can be expressed as… RDF
properties
-
- this twists your mind a bit, but you can get used to it
-
For example, (P rdfs:range C) means:
-
-
P is a property
-
C is a class instance
- 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
