I've followed this with great interest! I've been tinkering with the
same things, mostly in conjunction with my Oort project [1]. I had
actually begun sketching on a JSON format I call Gluon just as this
discussion appeared (inspired by jRDF, irON, GData-in-JSON and
others). To wrap my head around it more, I've spent some time recently
to elaborate on my examples and write an initial working
implementation in Python. To pitch it:

"Gluon is a JSON format for RDF. It has a full syntax covering
properties, resource references, bnodes and literals with optional
datatype or language. With profiles, more more succinct forms are

I think that it covers many of the things you discuss here and at [2].
Of course it is an experimental design, but I hope it will be of
interest to you.

Until I've written a cohesive description at [3], I hope the specs
[4], examples [5] and implementation [6] may provide you with insight
into the design decisions I've made. Especially the compact example at
[7] describes how to make the JSON more "natural".

(Early last year I made SPARQLTree [8], which has influenced my design
somewhat and may also be interesting to you.)

Depending on how things develop, I'd be happy to contribute to [2] if
that's suitable.

(.. I'm also sketching on how to use the "profile" mechanisms to
define a language-agnostic way of accessing RDF graphs as "plain"
objects (which may update/replace my current Object-RDF mapping
solution in "Oort the python package" from which "Oort the umbrella
project" stems). Of course this also relates to e.g. the API
vocabulary and programmatic (js) access to JSON-with-references ideas
which Jeni and Mark have discussed.)
