RE: Time Ontology: suspected error in alignment with Prov

Your observation is correct.
The alignment will be corrected (though time:inXSDDateTime is deprecated).

Subject: Time Ontology: suspected error in alignment with Prov

Hi all,

I suspect there is an error in section 5.7 of the Time ontology: Alignment of PROV-O with OWL-Time (https://www.w3.org/TR/owl-time/#time-prov).

This section states:
The prov:atTime property of an prov:InstantaneousEvent is directly related to :inXSDDateTimeStamp.
prov:atTime rdfs:subPropertyOf time:inXSDDateTimeStamp .

However, PROV-O defines prov:atTime as
:atTime rdfs:range xsd:dateTime .

While OWL-Time defines time:timeinXSDDateTimeStamp as:
 :inXSDDateTimeStamp rdfs:range xsd:dateTimeStamp .

Since prov:atTime is defined as the sub property, but has a broader domain, I believe this is an error.

Best regards,
