I agree, but this arises from the existing of a special graph called
default and the somewhat non-standard use of the word "default". A
longer but more accurate name might be, the "graph that cannot be
named or referred to of which there is only one where we put triples
that we can't think of a better place to put".
This could easily be solved by putting
default_graph = http://some.name/graph
in your sparqlserver.ini file and then manage the contents of that
named graph whatever way you see fit.
We do not need the notion of "default graph" in the core RDF specs! It
is a mistake. Please let us get rid of it.
