Term: RoleType

The source or destination of a RelationshipType.

RoleTypes are defined in the Model as part of the definition of a RelationshipType. They cannot be defined independently. RelationshipType inheritance is defined indirectly through RoleType inheritance; that way, source and destination roles can be redefined in the subtype of a RelationshipType.
