IrreflexiveRelation 
BinaryPredicate  singleValuedinverseA Predicate relating two items - its valence is two

Predicate 
TemporalRelation  valencesubrelationThe Class of temporal Relations. This Class includes notions of (temporal) topology of intervals, (temporal) schemata, and (temporal) extension
(forall (?INT) (domain exhaustiveDecomposition ?INT Class))
Relation 
existantTimePositionPhysicalvalencesubrelationThis relation holds between an instance of Physical and an instance of TimePosition just in case the temporal lifespan of the former includes the latter. The constants located and existant are the basic spatial and temporal predicates, respectively
