Hi Markus, Thanks.
I updated the configuration and now I have some results, although I was quite sure i tried this settings before. Next step is to find out what happen if i have 2 SMW's on Virtuoso. With 4Store i use 2 instances and it works fine. Giovanni PS. working conf SMW 1.17 beta and virtuoso-opensource-6.1 $smwgDefaultStore = 'SMWSparqlStore'; $smwgSparqlDatabase = 'SMWSparqlDatabase'; // for 4Store $smwgSparqlQueryEndpoint = 'http://localhost:8890/sparql/'; $smwgSparqlUpdateEndpoint = 'http://localhost:8890/update/'; $smwgSparqlDataEndpoint = ''; // can be empty .. [SPARQL] ;ExternalQuerySource = 1 ;ExternalXsltSource = 1 ;DefaultGraph = http://localhost:8890/DAV ResultSetMaxRows = 10000 MaxQueryCostEstimationTime = 400 ; in seconds MaxQueryExecutionTime = 60 ; in seconds DefaultQuery = select distinct ?Concept where {[] a ?Concept} DeferInferenceRulesInit = 0 ; controls inference rules loading ..
