mutualAcquaintance 
(mutualAcquaintance ?H1 ?H2) means that ?H1 and ?H2 have met each other and know something about each other, such as name and appearance. Statements made with this predicate should be temporally specified with holdsDuring. See also the weaker, nonsymmetric version of this predicate, acquaintance.

Instances  abstrait  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. 
 pr�dicat binaire  A Predicate relating two items  its valence is two. 
 relation binaire  BinaryRelations are relations that are true only of pairs of things. BinaryRelations are represented as slots in frame systems. 
 entit�  The universal class of individuals. This is the root node of the ontology. 
 InheritableRelation  The class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate. 
 predicat  A Predicate is a sentenceforming 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'. 
 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. 
 relation sym�trique  A BinaryRelation ?REL is symmetric just iff (?REL ?INST1 ?INST2) imples (?REL ?INST2 ?INST1), for all ?INST1 and ?INST2.
