Pierre,
The report is accurate there were no big improvements since that
publications. The key issue is that Virtuoso uses built-in SQL data
types whenever possible. Say, there's no xsd:boolean (it's stored as
plain integer 1 or 0). SPARQL compiler rejects some queries that are
formally correct bu
What is the Virtuoso SPARQL conformance with W3C recommandation (*) ?
Is SPARQL Implementation Coverage Report (**) accurate?
