OWLOOP enables interaction with 'OWL entities', i.e, Concept (also known as, Class), Individual, Object property and Data property as objects within the OOP paradigm. These objects are termed as Descriptors. A descriptor is composed of three parts, i.e, Ground, Expression and EntitySet.

  • A descriptor's Ground: is an OWL entity.
  • A descriptor's Expression: represents an expression (or expressions) of the Ground.
  • A descriptor's EntitySet: is a set of OWL entities associated to the to the Ground via an Expression.

Quick example:

  • A descriptor's Ground (of OWL entity type OWLClass): Socrates
  • A descriptor's Expression: SubClassOf
  • A descriptor's EntitySet (of OWL entity type OWLClass): [Human, Mortal]
