Hi Everyone,
I use evn 5.3.
I try to write sparqlmotion script thats exports exports taxonomies.
I need to change skos:hasTopConcept property in result set.
For make this do next:
1. For building resultset I use sml:ApplyConstruct with query inside:
CONSTRUCT {
?a ?b ?c .
}
WHERE {
{
SELECT ?a ?b ?c
WHERE {
{
{
BIND (IRI(?selectedGraph) AS ?graphName) .
BIND (IRI(?nodeURI) AS ?taxUri) .
GRAPH ?graphName {
?a (skos:broader)* ?taxUri .
?a ?b ?c .
} .
} .
}
UNION
{
BIND (IRI(?selectedGraph) AS ?graphName) .
GRAPH ?graphName {
?a a skos:ConceptScheme .
?a ?b ?c .
} .
} .
}
} .
}
2. on the next step I try to use the sml:PerformUpdate
2.1. In case of using next query:
DELETE {
?a skos:hasTopConcept ?oldValue .
}
INSERT {
?a skos:hasTopConcept ?newValue .
}
WHERE {
BIND (IRI(?nodeURI) AS ?newValue) .
?a ?b ?c .
?a skos:hasTopConcept ?oldValue .
}
I got NullPointerException in log
