Nicola: See:[1] http://bit.ly/1icgvnS -- DESCRIBE based query solution with define sql:describe-mode "CBD" (Concise Bound Description) pragma
[2] http://bit.ly/QvbLy5 -- Without the CBD pragma.In a related post, on a different Virtuoso support forum (I think github) I stated:
This matter is a little complicated due to:1. DESCRIBE being under specified at the SPARQL spec level -- so we have to use pragmas to cover all the different scenarios 2. Named Graph scope -- i.e., you need to factor this into your queries via GRAPH <IRI> or GRAPH ?g
[1] http://docs.openlinksw.com/virtuoso/rdfsparql.html#rdfsqlfromsparqldescribe -- description of the DESCRIBE pragmas with examples.
Hope this helps. Kingsley
