> Project: Apache Jena
> Issue Type: Bug
> Reporter: Vladimir Alexiev
> Priority: Major
>
> (related to https://github.com/schemaorg/schemaorg/issues/1781)
> On a query like this:
> {noformat}
> PREFIX schema: <http://schema.org/>
> PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
> select * {
> bind("2022-01-01"^^schema:Date < "02022-01-02"^^schema:Date as ?x1)
> bind(str("2022-01-01"^^schema:Date) < str("02022-01-02"^^schema:Date) as
> ?x2)
> bind("2022-01-01"^^xsd:date < "02022-01-02"^^xsd:date as ?x3)
> bind("1"^^schema:Integer < "02"^^schema:Integer as ?x4)
> bind(str("1"^^schema:Integer) < str("02"^^schema:Integer) as ?x5)
> bind("1"^^xsd:integer < "02"^^xsd:integer as ?x6)
> }
> {noformat}
> - http://sparql.org/sparql.html returns UNDEF for ?x3
> - arq returns
> {noformat}
> WARN NodeValue :: Datatype format exception: "02022-01-02"^^xsd:date
> {noformat}
> But according to https://en.wikipedia.org/wiki/ISO_8601#Years, one can use
> more than 4 digits (to accommodate years >10000).
> Negative years are also allowed, but sparql.org returns UNDEF for comparison
> of "-2022-01-02"^^xsd:dateTime
