Error Displaying Classes with Axioms

[mdebellis]

I originally sent this to the User Support for Protege email list: I've been working with Nivedita Dutta on a dental materials ontology. We wanted to start using Web Protege to share the ontology so we can edit concurrently and not worry about over-writing each other's work. If anyone feels like taking a look, the ontology is here: https://webprotege.stanford.edu/#projects/96174507-565e-4798-8cdf-788abf7fb753/edit/Classes

and I set the permissions so anyone can view it.

When I uploaded the ontology to Web Protege and started clicking on classes I keep getting the error shown below:

I get that error when I select random classes in the ontology. All I did was to upload the ontology to Web Protege and then change some of the settings. Specifically I changed the default IRI to be our IRI not the WebProtege IRI and I changed the default for new entities to be user supplied IRIs rather than UUIDs. It lets me select a few classes but then it starts giving me the error "Not a Datatype".

I think it has something to do with the classes that have axioms on them such as Adult and Child. Also, there are a lot of different IRIs in the ontology. We are reusing many classes from OBO especially the Oral Health and Disease ontology and we retained the OBO IRIs. Also, we're using a few classes from Prov-O: Agent and Organization. As well as properties and classes from SKOS and Dublin Core. But I've had ontologies with many different IRIs before and it isn't a problem.

I also uploaded the latest version of the ontology from Desktop Protege here in case anyone wants to take a look: https://drive.google.com/file/d/1rX5KeiQUlT_YeSduzcKwi1oaxA9_Hvy7/view?usp=sharing
