uniqueIdentifier
The class of names that uniquely identify an instance of Entity. Some examples of uniqueIdentifiers are the keys of tables in database applications and the ISBN (International Standard Book Number).
Relationships      
Parents names (names ?STRING ?ENTITY) means that the thing ?ENTITY has the SymbolicString ?STRING as its name. Note that names and represents are the two immediate subrelations of refers. The predicate names is used when the referring item is merely a tag without connotative content, while the predicate represents is used for referring items that have such content.
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.
 BinaryPredicateA Predicate relating two items - its valence is two.
 BinaryRelationBinaryRelations are relations that are true only of pairs of things. BinaryRelations are represented as slots in frame systems.
 EntityLa clase universal de individuos. Es el nodo principal de la ontologĂ­a.
 InheritableRelationThe class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.
 PartialValuedRelationA Relation is a PartialValuedRelation just in case it is not a TotalValuedRelation, i.e. just in case assigning values to every argument position except the last one does not necessarily mean that there is a value assignment for the last argument position. Note that, if a Relation is both a PartialValuedRelation and a SingleValuedRelation, then it is a partial function.
 PredicateA 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'.
 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.
 SingleValuedRelationA Relation is a SingleValuedRelation just in case an assignment of values to every argument position except the last one determines at most one assignment for the last argument position. Note that not all SingleValuedRelations are TotalValuedRelations.
