Relationships




Instances  abstract  Properties 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. 
 binary relation  BinaryRelations are relations that are true only of pairs of things. BinaryRelations are represented as slots in frame systems. 
 entity  The universal class of individuals. This is the root node of the ontology. 
 function  A Function is a termforming Relation that maps from a ntuple of arguments to a range and that associates this ntuple 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. 
 inheritable relation  The class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate. 
 probability relation  The Class of Relations that permit assessment of the probability of an event or situation. 
 relation  The Class of relations. There are two kinds of Relation: Predicate and Function. Predicates and Functions both denote sets of ordered ntuples. The difference between these two Classes is that Predicates cover formulaforming operators, while Functions cover termforming operators. 
 single valued relation  A 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. 
 total valued relation  A 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. 
 unary function  The Class of Functions that require a single argument.
