Smalyshev added a comment. I think this particular tickes is rather about how our Blazegraph instance understands xsd:datetime type. Right now it understands it strictly as XSD 1.0. We may want to have an option for it to also accept XSD 1.1. There are several aspect of this:
1. How the data is stored in wikidata 2. How the data look in RDF - e.g. does 2BCE look like `"-0001-01-01T00:00:00"^^xsd:dateTime` (XSD 1.1) or `"-0002-01-01T00:00:00"^^xsd:dateTime` (XSD 1.0) 3. How SPARQL engine understand the data - i.e., how many days are between `"0001-01-01T00:00:00"^^xsd:dateTime` and `"-0001-01-01T00:00:00"^^xsd:dateTime`. These three are distinct questions. I think this ticket is about the third one - though of course the previous two are important too and need to be handled.
