person-with-friend.owl
In this ontology we define a pwf:Person (a kind of Digital Subject class and a pwf:friend (a kind of higgins:attribute) property (as well as pwf:firstname and pwf:surname). (For the sake of simplicity in this example we've rolled our own "friend" relationship; in practice we'd try to build off existing schemas like FOAF, etc.)
The entire ontology is here. Within it you'll see that the friend property is defined as:
<owl:ObjectProperty rdf:ID="friend"> <rdfs:subPropertyOf rdf:resource="&higgins;#attribute"/> <rdfs:domain rdf:resource="&higgins;#DigitalSubject"/> <rdfs:range rdf:resource="&higgins;#SubjectRelationship"/> </owl:ObjectProperty>
