Error loading turtle data with datetime values

Support Bug
1

Hi

I'm trying to find out exactly which versions of RDF and XML Schema, Stardog (7.6.4) is supporting. I tried loading data in turtle format using the CLI tools which had literal values such as:

  • "0000-01-01T00:00:00Z"^^xsd:dateTime

However it reports:

  • There was a fatal failure during preparation of 3d889864-0c64-4145-823e-19adf8f5dfc7 com.stardog.stark.io.InvalidRDF: '-0000-01-01T00:00:00Z' is not a valid value for datatype XML Schema

There are other similar values it reports the error on too. This appears to be an XML Schema 1.0 vs 1.1 related issue. I was able to use such a datetime value in a SPARQL query in Stardog Studio.

I'm struggling to find any information on this in the documentation and whether i need to enable a feature or change a config property, or if this is a limitation.

Thanks

Tony
