has ontology hierarchical property 2025-09-17 The Developing Mouse Brain Atlas Ontology (DBMA) ontology uses part-of in its hierarchy, so this would correspond to the following turtle: `<https://purl.brain-bican.org/ontology/dmbao/dmbao.owl> a owl:Ontology; OMO:0003014 rdfs:subClassOf, BFO:0000050`. Relates an ontology to predicates/properties that should be used by user interfaces to render the hierarchical structure of the ontology. Typically, this is rdfs:subClassOf, but in ontologies that are partonomies, this might also include BFO:0000050 (part of). Tools like OLS can use predicates annotated with this property for rendering the ontology class hierarchy. There can be more than one hierarchical property. In the absence of any, it should be assumed that it is rdfs:subClassOf.
