daniel added a comment. I agree that we should gather more data before continuing the discussion about the interpretation of dates stored in wikidata.

Which version of ISO 8901, though? From Wikipedia: //ISO 8601:2004 (and previously ISO 8601:2000, but not ISO 8601:1988) explicitly uses astronomical year numbering in its date reference systems.// https://en.wikipedia.org/wiki/0_%28year%29#ISO_8601 ISO doesn't save us, since they made the same breaking change, just a few years earlier. If the spec or library docs don't explicitly say whether they use 8901:2000 or later, we might think they use ISO 8601:1988, which does the same as XSD 1.0: it does not allow year zero, and counts -1 as 1 BC.
