Hi,
I am trying to query sparql endpoint with sparql motion module of type
sml:ApplyConstruct, where sml:ApplyConstruct is set to:
CONSTRUCT {
?s ?p ?o .
}
WHERE {
SERVICE ?sparqlEndpoint {
GRAPH ?dataset {
?s ?p ?o .
} .
} .
}
?sparqlEndpoint and ?dataset are pointing to correct urls. Unfortunately
when i run script i get exception :
-
Operation failed. On: Apr 22, 2016 5:52:53 PM Reason:
java.lang.UnsupportedOperationException: Initial bindings not supported for

java.lang.Thread.run(Thread.java:745)
Am I doing something wrong ? Or is there any other module that i can use to
query concrete dataset of sparql endpoint ?
Thanks,
Peter G.
