roles "Tells which class and slot will take instances of this class depending on the role of the instance. The format is (role OWNER-CLASS |owner-slot|) e.g., if this class is DATE and the instance's role is recruitment-start-date, (recruitment-start-date RECRUITMENT |start-date|) tells us that this instance of date should be the value of the slot |start-date| in an instance of class RECRUITMENT."
