Subject Re: Fwd: issue in integrating relfinder with stanbol
Date Fri, 07 Jun 2013 06:49:07 GMT
Hi,

Isn't the count function SPARQL 1.1?

Currently the released version of Clerezza supports only SPARQL 1.0.
However the current snapshot version (trunk) has support for SPARQL 1.1.
When will this be released? Unfortunately I don't know.

Regards,

misl
