Hi Ivan,
thanks a lot for the explanation. The workaround looks crazy. :)

work either which is very confusing:

?mg nrl:coreGraphMetadataFor ?g .
FILTER(?g in ()) .

Hello Sebastian,
Unfortunately there's no way to calculate the graph to delete by
something more complicated than constant expression. If that creates
severe problems then I will extend the processor to support something
like
clear graph (

Hi list,
