Hi Manish, Stanbol uses the Clerezza SPARQL implementation. Therefore questions related to SAPRQL query support are better targeted to the Clerezza community.
But AFAIK count is not supported by the SAPRQL standard, but an extension supported by some SPARQL implementations (e.g. Jena) so most likely this is simple because Clerezza does not support it. best Rupert On Thu, Jun 6, 2013 at 4:23 PM, Garg, Manish <[email protected]> wrote: > HI Team > > we are trying to integrate relfinder with stanbol.
