year() function DOES NOT work in SPARQL (Protege)
This query throws an error
Unknown function 'http://www.w3.org/xpath-functions#year-from-dateTime'
My code:
select ?age where {
bind( "1799-12-14"^^<http://www.w3.org/2001/XMLSchema#date> as ?death )
bind( "1732-02-22"^^<http://www.w3.org/2001/XMLSchema#date> as ?birth )
bind(year(?death)-year(?death) AS ?age)
}
And I've been googling for so many hours without finding any helpful information. Do I have to add a prefix that refers to the function somewhere? Why on earth does protege not have built-in dateTime conversion functions?

bind( "1732-02-22"^^<http://www.w3.org/2001/XMLSchema#date> as ?birth )
bind(int(?death)-int(?death) AS ?age)
}
I've tried to cast the date to integer but that throws another error message. Does anyone know how to properly cast dateTime to int with Protege SPARQL?

See the discussion here - Protege is based on an older SPARQL API where many functions are not implemented. There is also a ticket on Github.

alternatively, you could use Apache Jena or RDF4J from command line for querying a local file
