depth
A TernaryPredicate that is used to state the distance between the top of an Object and another point that is above the top of the Object (often this other point will be sea level). Note that this Predicate can be used to specify, for example, the depth of marine life or submarines, for example.
Relationships      
Parents distance (distance ?OBJ1 ?OBJ2 ?QUANT) means that the shortest distance between the two objects ?OBJ1 and ?OBJ2 is ?QUANT. Note that the difference between the predicates length and distance is that the length is used to state the LengthMeasure of one of the dimensions of a single object, while distance is used to state the LengthMeasure that separates two distinct objects.
InstancesAstrattoProperties 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.
 Entit�The 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.
 PredicatoA 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'.
 RelazioneThe 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.
 RelazioneMonovalenteA 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.
 RelazioneSpazialeThe Class of Relations that are spatial in a wide sense. This Class includes mereological relations and topological relations.
 PredicatoTernarioThe Class of Predicates that require exactly three arguments.
 RelazioneTernariaTernaryRelations relate three items. The two subclasses of TernaryRelation are TernaryPredicate and BinaryFunction.
 RelazioneAValoreTotaleA 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.
