I want to have SPARQL queries on http://192.168.0.79:9999/blazegraph return inferred triples, so that after loading the data at http://learningsparql.com/2ndeditionexamples/ex417.ttl I can query for dc:creator values and see the dm:composer and dm:photographer values returned. I was able to do a query on dm:photographer with no problem, but couldn 't get at any inferred triples. Based on what I saw at https://wiki.blazegraph.com/wiki/index.php/SPARQL_Update#Manage_truth_maintenance_in_SPARQL_UPDATE, on http://192.168.0.79:9999/blazegraph/#update I entered ENABLE ENTAILMENTS with a Type of "SPARQL Update" selected underneath. This gave me a bunch of errors starting with this: java.util.concurrent.ExecutionException: java.util.concurrent.ExecutionException: org.openrdf.query.UpdateExecutionException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.ArrayIndexOutOfBoundsException: 3 I had hoped that ENABLE (or CREATE) ENTAILMENTS as an update request would let me query for the dc:creator values. Is this possible? What am I doing wrong? Thanks, Bob |
