Property "has endpoint" is missing from BAO property tree.

[mdorf]

Per a user report on the support list, the property "has endpoint" does not appear in the UI display of the ontology properties:

https://bioportal.bioontology.org/ontologies/BAO/?p=properties

A quick check of the /properties REST endpoint revealed that the property IS present in the result: https://data.bioontology.org/ontologies/BAO/properties

I believe the cause of the issue is in this code in the Ruby Client: https://github.com/ncbo/ontologies_api_ruby_client/blob/master/lib/ontologies_api_client/models/ontology.rb#L83

This code filters out all properties that have parents. The property "has endpoint" (http://www.bioassayontology.org/bao#BAO_0000208) does have a parent with ID "http://www.w3.org/2002/07/owl#topObjectProperty"

A further investigation is required on the proper fix for this issue.

I don't think there's an issue in the code - the property isn't missing as the end user originally reported.

has endpoint is present in the property tree underneath topObjectProperty:

I believe this is the correct graphical representation because the ontology authors declared this property as a sub-property of topObjectProperty:

There are other object properties displayed at the root of the property tree, and it's due to a lack of any subPropertyOf description. To follow are two axioms where the difference is visible:
