This paper introduces the E/S knowledge representation model and describes a system based on that model. The model takes ideas from KL-ONE and ER, and its main strength is the direct representation of n-ary relationships. The system is classification-based, and therefore organizes its knowledge in hierarchies of structured intensional objects and offers a set of services to reason about intensional objects, to store extensional objects and to make inferences on the stored knowledge.
