RDF implementation for Shuffl, via RDF-in-JSON

I'm throwing my hat into the RDF-in-JSON ring, planning an implementation of RDF/XML serialization for Shuffl workspaces and cards using RDFQuery [1] and JRON [2].  My initial mdesign notes are at http://code.google.com/p/shuffl/wiki/JRON_implementation_notes.
