Hi Geert,
I am running this script now. It runs w/o error but doesnt return ant
results. I am not sure if, I am missing something here. Also, I am not sure
how to pass my data in query like, I want to get all banks in uk.
let $my-store := sem:ruleset-store("/rules/bankAt.rules", sem:store() )
return
(: use the store you just created - pass it in to sem:sparql() :)
sem:sparql('
PREFIX ex: <http://example.com/>
PREFIX gn: <http://www.geonames.org/ontology/>
SELECT ?bank ?placeName
FROM <http://marklogic.com/semantics/sb/banks/inf-1>
WHERE
{
?bank ex:bankAt ?place .
?place gn:name ?placeName
}
ORDER BY ?bank
', (), (),
$my-store
)
