Dear all,

I could not figure out any way to use ACLs to avoid showing private
graphs when submitting the following query:

SELECT DISTINCT ?g WHERE {GRAPH ?g {?s ?p ?o}}

The query should not be changed, so I was hoping to be able to do it via
graph-level permissions and/or pragmas. Is it possible to do this at all?

Thanks a lot,

Nicola

Via SQL Command Line or Conductor UI (HTML based Administrator):

-- Add a named graph to the private (protected) graph group

DB.DBA.RDF_GRAPH_GROUP_INS ('http://www.openlinksw.com/schemas/virtrdf#PrivateGraphs','{named-graph-iri') ;

DB.DBA.RDF_DEFAULT_USER_PERMS_SET ('nobody', 0, 1);



DB.DBA.RDF_DEFAULT_USER_PERMS_SET ('SPARQL', 0, 1);
