public interface AssociationRoleIF extends TypedIF, ReifiableIF
PUBLIC: Implemented by objects representing association roles in the topic map model. Association roles are first-class objects which represent a topic playing a role in an association.

Note: in XTM 1.0 terminology, associations have members playing roles in the association. In ISO 13250 terminology, playing a role in an association is a characteristic of a topic. These notions are intended to be equivalent.
