Querying a set of named RDF graphs without naming the graphs

A big step toward using named graphs to track provenance.

I’d like to thank everyone who added comments to my last post, Some questions about RDF named graphs. Lee Feigenbaum wrote an entire blog post addressing the issues I raised, and it looks like his Open Anzo triplestore (which I’ll write up in its own post soon) has some nice support for versioning, access control, and replication.
