Actually I am performing benchmarking with virtuoso and by default certain
graphs and quads are already present in it. And I am not able to delete
them. Therefore I am curious if I could store all my quads in a separate
place (like a super graph), which would allow me to perform benchmarking.
Also is there a way to delete all the default graphs and quads in virtuoso
before loading new quads into it.
Thanks a lot for helping
