At some point I started thinking that indexing just triples should work
just fine even with quads. Than various graphs could have their own
database (sublevel) if one wants to search just in that graph e.g. a
graph for each void:Dataset named with URIs same to string used for it's
void:uriSpace Or named with URIs denoting agents who created those
triples. Different use cases could use different approaches for naming
graphs.

One database (sublevel) could keep merged graph with additional property
(not indexed) about in which named graphs that triple appears.

Just thinking out loud ...
