Parents beforeOrEqual (beforeOrEqual ?POINT1 ?POINT2) means that ?POINT1 is identical with ?POINT2 or occurs before it on the universal timeline.
InstancesAbstractProperties or qualities as distinguished from any particular embodiment of the properties/qualities in a physical medium. Instances of Abstract can be said to exist in the same sense as mathematical objects such as sets and relations, but they cannot exist at a particular place and time without some physical encoding or embodiment.
 BinaryRelationBinaryRelations are relations that are true only of pairs of things. BinaryRelations are represented as slots in frame systems.
 EntityThe universal class of individuals. This is the root node of the ontology.
 InheritableRelationThe class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.
 IrreflexiveRelationRelation ?REL is irreflexive iff (?REL ?INST ?INST) holds for no value of ?INST.
 RelationThe Class of relations. There are three kinds of Relation: Predicate, Function, and List. Predicates and Functions both denote sets of ordered n-tuples. The difference between these two Classes is that Predicates cover formula-forming operators, while Functions cover term-forming operators. A List, on the other hand, is a particular ordered n-tuple.
 TemporalRelationThe Class of temporal Relations. This Class includes notions of (temporal) topology of intervals, (temporal) schemata, and (temporal) extension.
 TransitiveRelationA BinaryRelation ?REL is transitive if (?REL ?INST1 ?INST2) and (?REL ?INST2 ?INST3) imply (?REL ?INST1 ?INST3), for all ?INST1, ?INST2, and ?INST3.
