Thanks Geert,
I have already created rule for inferencing by:
xquery version "1.0-ml";
xdmp:document-insert(
'/rules/bankAt.rules',
text{
'
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema/>
PREFIX ex: <http://example.com/>
PREFIX gn: <http://www.geonames.org/ontology/>
rule "bankAt" CONSTRUCT {
?bank ex:bankAt ?place2
} {
?bank ex:bankAt ?place1 .
?place1 gn:parentFeature ?place2
}
'
}
)
And this is running w/o error. My issue is I am trying to use it in my
query like
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/>
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
)
This is giving me error. I am confused on how to use custom rule
(syntatically)
