A turn around is to create an OWL class in order to represent a relation, with related and relating properties. It provides the ability to capture properties for instances of relations. Using OWL Paths, it is also possible to create inferences of an associated OWL property. Attention should be payed to the fact OWL DL is about to describe what is always true, not things. which are mutable. So time and space context is to be defined with unmutability in order being able to use reasonning based on descritptive logic.
