Hi Hugh,
Explicitly or implicitly created, I would think that if a graph
containing triples existed in the system, that:
select distinct ?g where {?graph ?g {?s ?p ?o}}
would list that graph. Some of the triples make it in and those triples
are query able such as in:
select ?g ?s ?o where {graph ?g {?s :knownpredicateinphantomgraph ?o}}
will list the URI of the phantom graph with this query, just not in the
first SPARQL query above.
Is there a table that keeps a list of named graphs or does
DB.DBA.SPARQL_SELECT_KNOWN_GRAPHS() actually query the quad store to
determine this list?

Hi Erich,
it seems as if the graph was not explicitly created as a result of the
error in the turtle file, thus it was silently created. The following
document details the use of create graph to explicitly create a graph:

After calling:
CREATE GRAPH <http://www.ebremer.com/ips>
The graph now shows up in the list of graphs (and the one triple). -

Hi,
I'm been loading and reloading graphs in V7.0.0 and on one
particular load, the graph would not load. It turned out that I had an
error in the turtle file I was loading, but, it seems one triple from
the file loaded. I can see this triple if I sparql for it, but, the
graph that I was loading it into does not show in the conductor list of
graphs, nor does it show up in the query:
select distinct ?g where {graph ?g {?s ?p o}}
but, it I query for the named graph:
select * where {graph <http://www.ebremer.com/ips> {?s ?p ?o}}
the one triple will show up. - Erich
