I'd like to be able to use SPARQL to get a list of all named graphs. 
(StoreUtils.storeGraphNames(store) will get that list in code, of course.)

I know that if the name of my graph and the "main" subject in it are the same 
(which is true in my case) I can do:

SELECT DISTINCT ?g
WHERE {
                 {GRAPH ?g {?g ?p ?o}}

                   {GRAPH ?g {?s ?p ?o}}

}

but that appears to take a long time. Using storeGraphNames() seems pretty much 
instantaneous and is more general.

Is there any way to do what I want?

Thanks,

GRAPH ?g {}
