properPart
(properPart ?OBJ1 ?OBJ2) means that ?OBJ1 is a part of ?OBJ2 other than ?OBJ2 itself. This is a TransitiveRelation and AsymmetricRelation (hence an IrreflexiveRelation).
Relationships      
Parents part The basic mereological relation. All other mereological relations are defined in terms of this one. (part ?PART ?WHOLE) simply means that the Object ?PART is part of the Object ?WHOLE. Note that, since part is a ReflexiveRelation, every Object is a part of itself.
Children engineeringSubcomponent(engineeringSubcomponent ?SUB ?SUPER) means that the EngineeringComponent ?SUB is structurally a properPart of ?SUPER. This relation is an AsymmetricRelation, since two EngineeringComponents cannot be subcomponents of each other.
 geographicSubregion(geographicSubregion ?PART ?WHOLE) means that the GeographicArea ?PART is part of the GeographicArea ?WHOLE.
 physicalEndA notion of an indeterminate portion at the end of an Object that has a LongAndThin ShapeAttribute.
 streamOutfall(streamOutfall ?WATER ?RIVER) means that the WaterArea ?MOUTH is the outfall of the River ?RIVER.
InstancesabstraitProperties 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.
 relation antisym�triqueBinaryRelation ?REL is an AntisymmetricRelation if for distinct ?INST1 and ?INST2, (?REL ?INST1 ?INST2) implies not (?REL ?INST2 ?INST1). In other words, for all ?INST1 and ?INST2, (?REL ?INST1 ?INST2) and (?REL ?INST2 ?INST1) imply that ?INST1 and ?INST2 are identical. Note that it is possible for an AntisymmetricRelation to be a ReflexiveRelation.
 relation asym�triqueA BinaryRelation is asymmetric if and only if it is both an AntisymmetricRelation and an IrreflexiveRelation.
 pr�dicat binaireA Predicate relating two items - its valence is two.
 relation binaireBinaryRelations are relations that are true only of pairs of things. BinaryRelations are represented as slots in frame systems.
 entit�The 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.
 relation irr�flexiveRelation ?REL is irreflexive iff (?REL ?INST ?INST) holds for no value of ?INST.
 relation partiellement dirig�eA BinaryRelation is a partial ordering if it is a ReflexiveRelation, an AntisymmetricRelation, and a TransitiveRelation.
 predicatA Predicate is a sentence-forming Relation. Each tuple in the Relation is a finite, ordered sequence of objects. The fact that a particular tuple is an element of a Predicate is denoted by '(*predicate* arg_1 arg_2 .. arg_n)', where the arg_i are the objects so related. In the case of BinaryPredicates, the fact can be read as `arg_1 is *predicate* arg_2' or `a *predicate* of arg_1 is arg_2'.
 relation r�flexiveRelation ?REL is reflexive iff (?REL ?INST ?INST) for all ?INST.
 relationThe Class of relations. There are two kinds of Relation: Predicate and Function. 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.
 relation spatialThe Class of Relations that are spatial in a wide sense. This Class includes mereological relations and topological relations.
 relation totalA Relation is a TotalValuedRelation just in case there exists an assignment for the last argument position of the Relation given any assignment of values to every argument position except the last one. Note that declaring a Relation to be both a TotalValuedRelation and a SingleValuedRelation means that it is a total function.
 relation transitiveA BinaryRelation ?REL is transitive if (?REL ?INST1 ?INST2) and (?REL ?INST2 ?INST3) imply (?REL ?INST1 ?INST3), for all ?INST1, ?INST2, and ?INST3.
