connects
The relationship between three things, when one of the three things connects the other two. More formally, (connects ?OBJ1 ?OBJ2 ?OBJ3) means that (connected ?OBJ1 ?OBJ2) and (connected ?OBJ1 ?OBJ3) and not (connected ?OBJ2 ?OBJ3).
Relationships      
Children connectsEngineeringComponentsconnectsEngineeringComponents is a TernaryPredicate that maps from an EngineeringConnection to the EngineeringComponents it connects. Since EngineeringComponents cannot be connected to themselves and there cannot be an EngineeringConnection without a connectedEngineeringComponents Predicate, the second and third arguments of any connectsEngineeringComponents relationship will always be distinct for any given first argument.
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.
 EntityThe universal class of individuals. This is the root node of the ontology.
 InheritableRelationThe class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.
 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 three kinds of Relation: Predicate, Function, and List. 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. A List, on the other hand, is a particular ordered n-tuple.
 SpatialRelationThe Class of Relations that are spatial in a wide sense. This Class includes mereological relations and topological relations.
 TernaryPredicateThe Class of Predicates that require exactly three arguments.
 TernaryRelationTernaryRelations relate three items. The two subclasses of TernaryRelation are TernaryPredicate and BinaryFunction.
