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.
Relationships      
Children componentA specialized common sense notion of part for heterogeneous parts of complexes. (component ?COMPONENT ?WHOLE) means that ?COMPONENT is a component of ?WHOLE. Examples of component include the doors and walls of a house, the states or provinces of a country, or the limbs and organs of an animal. Compare piece, which is also a subrelation of part.
 genetic substrate of virus(geneticSubstrateOfVirus ?VIRUS ?MOL) relates the virus ?VIRUS to the molecule ?MOL that contains its genetic information.
 half(half ?HALF ?WHOLE) means that ?HALF is one half of ?WHOLE.
 inString(inString ?Character ?SymbolicString) means that ?Character is part of ?SymbolicString. See also subString.
 interior part(interiorPart ?OBJ1 ?OBJ2) means that ?OBJ1 is part ?OBJ2 and there is no overlap between ?OBJ1 and any superficialPart ?OBJ2.
 most(most ?MOST ?WHOLE) means that ?MOST is a part of ?WHOLE that is greater than half of ?WHOLE.
 path in system(pathInSystem ?PATH ?SYSTEM) means that the Physical thing ?PATH consists of one or more connected routes in the PhysicalSystem ?SYSTEM.
 pieceA specialized common sense notion of part for arbitrary parts of Substances. Quasi-synonyms are: chunk, hunk, bit, etc. Compare component, another subrelation of part.
 proper part(properPart ?OBJ1 ?OBJ2) means that ?OBJ1 is a part of ?OBJ2 other than ?OBJ2 itself. This is a TransitiveRelation and AsymmetricRelation (hence an IrreflexiveRelation).
 quarter(quarter ?QUART ?WHOLE) means that ?QUART is a quarter of ?WHOLE.
 sub collection(subCollection ?COLL1 ?COLL2) means that the Collection ?COLL1 is a proper part of the Collection ?COLL2.
 subString(subString ?SymbolicString-1 ?SymbolicString-2) means that ?SymbolicString-1 is part of ?SymbolicString-2. ?SymbolicString-2 includes all the same Characters as ?SymbolicString-1 and in the same order, but ?SymbolicString-2 may include more Characters than ?SymbolicString-1. See also inString.
 third(third ?THIRD ?WHOLE) means that ?THIRD is one third of ?WHOLE.
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.
 antisymmetric relationBinaryRelation ?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.
 binary relationBinaryRelations 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.
 inheritable relationThe class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.
 partial ordering relationA BinaryRelation is a partial ordering if it is a ReflexiveRelation, an AntisymmetricRelation, and a TransitiveRelation.
 reflexive relationRelation ?REL is reflexive iff (?REL ?INST ?INST) for all ?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.
 spatial relationThe Class of Relations that are spatial in a wide sense. This Class includes mereological relations and topological relations.
 total valued relationA 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.
 transitive relationA BinaryRelation ?REL is transitive if (?REL ?INST1 ?INST2) and (?REL ?INST2 ?INST3) imply (?REL ?INST1 ?INST3), for all ?INST1, ?INST2, and ?INST3.
