I don't see why one would want to share Model instances via Spark. I

Hi Jason,
Models aren't serializable, nor are Graphs (the more system oriented
view of RDF) through Triples, Quads and Node are serializable. You can
send a list of triples.
Or use an RDF syntax and write-then-read the RDF.
But are the models small? RDF graph aren't always small so moving
