Is it still possible to dynamically load SPARQL functions from the classpath? I have it working with tarql, which uses Jena 3.11, but I can’t seem to get it working with the latest version of Jena:
$ JVM_ARGS="-cp /Users/ryanshaw/Code/ncg-dataset/lib/sparql-functions/build/libs/sparql-functions.jar" ./tools/apache-jena-4.8.0/bin/arq --data=dataset.nt --query=queries/new-ids.rq 19:36:15 WARN ClsLoader :: Class not found: org.ncgazetteer.mint 19:36:15 WARN exec :: URI <java:org.ncgazetteer.mint> has no registered function factory $ cat queries/new-ids.rq: PREFIX ncp: <http://n2t.net/ark:/39333/ncg/place/> PREFIX owl: <http://www.w3.org/2002/07/owl#> PREFIX f: <java:org.ncgazetteer.> CONSTRUCT { ?oldid owl:sameAs ?newid . } WHERE { SELECT DISTINCT ?oldid (f:mint("ncp") AS ?newid) WHERE { ?oldid ?p ?o .
