The modules of the biological core ontology GFO-Bio. GFO-Bio comes in two modules. The first focuses on individuals and defines categories of individuals like "Cell" or "Organism" in the Web Ontology Language (OWL). It contains 168 categories and 73 relations. The second treats categories as instances in OWL and describes interrelations between domains or whole domain ontologies. It is based on a theory of levels of reality and contains 43 categories and two additional relations. Both modules are related using the Semantic Web Rule Language [44] and DLVHEX rules.
