A partial order relation that holds between social objects.
It mainly represents the subsumption relation between e.g. a Concept or Description and another Concept (resp. Description) that is broader in extensional interpretation, but narrower in intensional interpretation. For example, the role PhDStudent specializes the role Student.
Another possible use is between a Collection that isCoveredBy a Concept A, and another Collection that isCoveredBy a Concept B that on its turm specializes A. For example, the 70,000 series Selmer Mark VI saxophone Collection specializes the Selmer Mark VI saxophone Collection.
