Hi Manu, JSONers,

Finally had the time to work through the new spec draft. Thank you
very much for your hard work, this looks like something I was hoping
for, and that I can perfectly live with. For what it's worth, I add a
"+1" from my side under this draft. What would be the concrete next
steps in order to push this forward in the RDF(a) WGs? What can I do?
Please do let me know how I can help. Not sure if you had more
feedback from people (I know of Gregg Kellog's email). Somehow no one
seemed to react on your email, at least not on the JSON list. I am
still a big supporter of JSON for serializing RDF, you know that :-)
Looking forward to pushing this forward.

Best,
Tom
