Hi Colin,
Export to RDF file actually does what it says on the tin—it exports the results
to an RDF file in the workspace. It doesn't work for updating a graph in the
system database.
The closest equivalent to Import RDF from Workspace in the other direction is
Perform Update, but that is not entirely safe to use for EDG graphs such as the
urn:x-evn-master:xxx ones.
Personally I would use SWP over SPARQLMotion for this kind of task. It's much
closer to a traditional programming/scripting language (but with a very strange
syntax, and an RDF/SPARQL-based type system).
