A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
HourFn
A BinaryFunction that assigns a PositiveRealNumber and a subclass of Days to the Hours within each Day corresponding to that NonnegativeInteger. For example, (HourFn 12 Thursday) is the Class of all instances of noon Thursday. For another example, (HourFn 0 Day) would return the class of all instances of midnight. For still another example, (HourFn 14 (DayFn 18 (MonthFn August (YearFn 1912)))) denotes 2 PM on the 18th day of August 1912.
Relationships      
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.
 BinaryFunctionThe Class of Functions that require two arguments.
 EntityLa clase universal de individuos. Es el nodo principal de la ontologĂ­a.
 FunctionA Function is a term-forming Relation that maps from a n-tuple of arguments to a range and that associates this n-tuple with at most one range element. Note that the range is a Class, and each element of the range is an instance of the Class.
 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.
 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.
 TemporalRelationThe Class of temporal Relations. This Class includes notions of (temporal) topology of intervals, (temporal) schemata, and (temporal) extension.
 TernaryRelationTernaryRelations relate three items. The two subclasses of TernaryRelation are TernaryPredicate and BinaryFunction.
