gives me the impression that conversion of a boolean to an integer
should work, but this query
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
SELECT ?oInt WHERE {
?s ?p ?o .
BIND (xsd:integer(?o) as ?oInt )
}
just comes up blank with this data:
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix ex: <http://ex/> .
ex:thing1 ex:required "true"^^xsd:boolean .
I'm using ARQ 2.8.8. Shouldn't it turn true into a 1 and false into a 0?
(Then again, the part of the spec referenced above says that this is
"allowed," not "required"...)
Hmm. Didn't catch that one. The rules for casting from boolean to a
numeric type are ... bizarre.
I'll fix the code for this case -- (curious) but why do you want to cast
boolean to integer in the first place?
