[bioontology-support] labels for Time ontology

I am not sure this is the reason for the failure to render the Time class hierarchy in Bioportal. The ontology includes a (xsd:dateTimeStamp rdfs:subClassOf rdfs:Literal) axiom. This mixing of datatype and class is not right.

With best regards,

Subject: labels for Time ontology


(not sure if you got copied on that first response, which is below)

Is it reasonable to think the Time ontology might get labels any time soon, which would save us from having to troubleshoot this?  (Just a shot in the dark, in case there are plans.)

I tried to register the W3C OWL-Time ontology last year.
Its listed here
Something went wrong, but I do not understand the error message.
In particular the class tree does not render properly.
This is now a W3C 'Recommendation' so I think merits listing in BioPortal.
Any comments?

I looked at the latest submission for the TIME ontology. During the parsing process in BioPortal, we have some code that generates labels for any classes don’t have labels declared. After generating that data, an error occurs when the system attempts to load it into the triplestore. The error is rather deep in the stack, and it wasn’t immediately obvious to me what the problem is. I’ve entered an issue in our tracker:

… so that we can spend some time debugging.

Kind regards,
