Hello Hugh, is there something new about this issue? In the meantime i need to insert RDF files on runtime (e.g it should be inserted as soon as the .n3 file is created). Is there a possibility to run the isql commands using a batchfile which execute the/ld_dir/ and /rdf_loader_run ()/ script

Hi, thank you. Will check this out. One further question: The SPARQL execution within Virtuoso does not allow me query foreign graphs (f.e http://dbpedia.org). I get no results at all. For testing i already did the same query using the DBpedia sparql endpoint - http://dbpedia.org/sparql -
