There is no ontology to Ontology, only epistemic intuition at best. What Ontology is, obviously and naturally, is part of the Universal Ontology of everything else.
Sooo, in sum, Ontology is the same for anything by definition and Occam's razor, hopefully simple, unlike incomplete human dabbling in Politics and Law school...
If you happen to believe the Ontology of what makes a painter a good painter is different from what makes a good engineer or a good farmer then you have yet to understand what Ontology really means.
Patterns and fractals are the same everywhere.
The nature of Ontology as a field is exactly the same as the Universal one, which by the way is the only brut fact Ontology there really is. The process is complete at some point in the future just like a Rubik's cube logarithm.
There is no Ontology before ALL the future becomes present!
(Oh my god this last sentence, it just came out of nowhere in my mind...thank you Ontology for giving me the luck of "invocare" it to life!)
