[Virtuoso-users] RDF_IRI cleanup

[Pierre De Wilde]

Hi,

When clearing a graph using SPARQL CLEAR GRAPH <iri>, it seems that the
table RDF_IRI is not cleared.I understand that some IRIs may be used by
other graphs but not always.

How can I delete RDF_IRI records not used in any (G,S,P,O) columns of
the RDF_QUAD table?
Why not include RDF_IRI deletion as part of SPARQL CLEAR GRAPH command?

Thanks beforehand for your help.

Pierre
