MonthFn
A BinaryFunction that maps a subclass of Month and a subclass of Year to the class containing the Month corresponding to that Year. For example (MonthFn August (YearFn 1912)) is the class containing the eighth Month, i.e. August, of the Year 1912. For another example, (MonthFn August Year) is equal to August, the class of all months of August. Note that this function returns a Class as a value. The reason for this is that the related functions, viz. DayFn, HourFn, MinuteFn, and SecondFn, are used to generate both specific TimeIntervals and recurrent intervals, and the only way to do this is to make the domains and ranges of these functions classes rather than individuals.
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.
 EntityThe universal class of individuals. This is the root node of the ontology.
 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.
