Also add docs on http://purl.obolibrary.org/obo/IAO_0000700 which is a really awesome feature

Good idea!

I think I have a broader question - how do I as an ontology provider override these defaults? e.g. if I want to indicate that a property is hierarchy, what OWL annotation do I provide?

[cmungall]

Just a ping on the Q above: is there a way I can state in my ontology which OPs are hierarchical?

[jamesamcl]

I don't think it's possible from OWL at the moment, I think it has to be done from the OLS config. We can look into implementing loading from the OWL though, it's done for lots of the other properties.

[henrietteharmse]

Definitely not possible currently.

@cmungall Do you have any thoughts on how to configure this from an ontology? Do you have any specific AP(s?) in mind for configuring this?
It would seem that a has hierarchical object property in IAO will be ideal.

I made the issue here information-artifact-ontology/ontology-metadata#84

let's see if someone has time to make a PR
