xsd:dateTime issue

[joegregoryphd]

When I build my description project, the reasoner returns the following error:

<rdf:RDF xmlns="urn:unnamed:ontology#ont1033382559725501#"

I am defining my time periods as follows:

ci OTE1_TimePeriod [
hasBeginInstant “2023-01-01T12:00:0”
]

How could I resolve this? Thanks

A quoted string without a ^^type is treated as a String literal leading to the inconsistency.

Change your dateTime literal to:

ci OTE1_TimePeriod [
hasBeginInstant “2023-01-01T12:00:0”^^xsd:dateTime
]

Thanks, this resolved the issue.
