[Virtuoso-users] NOT EXISTS keyword support in virtuoso SPARQL endpoints?

[Christian Fuerber]

Hi,

while using vos6, I discovered that the virtuoso SPARQL endpoints do not
support the NOT EXISTS keyword
(http://www.w3.org/TR/2009/WD-sparql11-query-20091022/#negation) at present.

Is there any virtuoso specific function that acts like it?

Thanks,
