Hello Tim, Here are the answers to your questions:
1-) In TopBraid Composer, you can specify a named graph as the baseURI or some other URI depending on the repository in export or import wizards. At the repository level, if it is a quad store, then there would be quads with the named graph URI, subject, predicate and object.
2-) In TopBraid Composer, "INSERT INTO <named-graph-URI>" would get the resulting triples into the named graph with the specified <named-graph-URI>, if the named graph exists within the workspace. That named graph would usually be the base URI of an .owl, .ttl or .n3 file or .oracle, .sdb, .tdb or .allegro connection file.
Outside TopBraid Composer, each semantic repository have their own implementation of named graphs.

I conceptually understand named graphs, but I cannot seem to find any basic information about how to use them. My two based questions are: 1 - I understand that named graphs are referenced by a URI. Do I first need to create an instance of a "named graph" in order to insert triples into it? If so, is there a "named graph" class? If not, will any old class do? 2 - Once I have a named graph, how do I get triples into it? It looks like CONSTRUCT won't do. Is INSERT INTO the right methd? What I am wanting to do it have multiple named graphs in a single Jena TDB store (or AllegroGraph, or OWL / N3 / etc. file). I just can't seem to figure out how to get things up and running. Any reference to "named graphs" for dummies will do. -Thanks-
