Yes, "documents and references" and "nodes and edges" is where things become fairly synonymous which is why I asked about RethinkDB supporting relational documents. I honestly think they are doing themselves a disservice by calling it a "JOIN" since that sounds slow and scary. If they wrapped it in a nice API like ".navigate()" or ".traverse()" I think it would be reasonable for them to advertise as a graph database! Tip to anybody at RethinkDB in case they are listening.
