Relationships      
Parents relation binaire BinaryRelations are relations that are true only of pairs of things. BinaryRelations are represented as slots in frame systems.
Children relation �quivalenteA BinaryRelation is an equivalence relation if it is a ReflexiveRelation, a SymmetricRelation, and a TransitiveRelation.
 relation partiellement dirig�eA BinaryRelation is a partial ordering if it is a ReflexiveRelation, an AntisymmetricRelation, and a TransitiveRelation.
Instancesconnected(connected ?OBJ1 ?OBJ2) means that ?OBJ1 meetsSpatially ?OBJ2 or that ?OBJ1 overlapsSpatially ?OBJ2.
 keyName(keyName ?S1 ?S2) means that ?S1 is the subString of ?S2 (i.e., the component name) typically used for alphabetical name indexing.
 overlapsSpatially(overlapsSpatially ?OBJ1 ?OBJ2) means that the Objects ?OBJ1 and ?OBJ2 have some parts in common. This is a reflexive and symmetric (but not transitive) relation.
 overlapsTemporally(overlapsTemporally ?INTERVAL1 ?INTERVAL2) means that the TimeIntervals ?INTERVAL1 and ?INTERVAL2 have a TimeInterval as a common part.
 subGraphThe relation between two Graphs when one Graph is a part of the other. (subGraph ?GRAPH1 ?GRAPH2) means that ?GRAPH1 is a part of ?GRAPH2.
 subString(subString ?SymbolicString-1 ?SymbolicString-2) means that ?SymbolicString-1 is part of ?SymbolicString-2. ?SymbolicString-2 includes all the same Characters as ?SymbolicString-1 and in the same order, but ?SymbolicString-2 may include more Characters than ?SymbolicString-1.
