A marker interface for classes, properties, individuals (including anonymous individuals) and datatypes. Entities are the fundamental building blocks of ontologies, and all entities are identified by a URI. Note that OWL 1.1 supports punning, which means that an OWLClass may have the same URI as an OWLIndividual (or other entity) but will still be considered to be a separate object.
