I've deployed SquirrelRDF and can now query my legacy RDB in SPARQL.
I'm pleased.

However, I'm mainly interested in querying across multiple RDF data
sources. Eg I'd like to merge data from this RDB with data about
similar resources in my big triplestore.

I've previously used MultiUnion.addGraph() to stick together multiple
models, before passing that to the QueryExecution. How can I get the
'graph' view on the data with SquirrelRDF? Or, am I missing the point
- is there a graph view?

Or, is there another way you suggest I go about merging when one is a
SquirrelRDF source?

Thanks,
Katie
