I'd be curious to see an example of the "pandoc JSON" if you could point me to one (and/or your python prototype).

You can “live”-produce one yourself in a terminal window with the help of pandoc, using simple Markdown input:

kp@mbp> pandoc -t json

# Headline

Paragraph.

List:

1. One
1. Two

^D

[{"unMeta":{}},[{"t":"Header","c":[1,["headline",[],[]],[{"t":"Str","c":"Headline"}]]},{"t":"Para","c":[{"t":"Str","c":"Paragraph."}]},{"t":"Para","c":[{"t":"Str","c":"List:"}]},{"t":"OrderedList","c":[[1,{"t":"Decimal","c":[]},{"t":"Period","c":[]}],[[{"t":"Plain","c":[{"t":"Str","c":"One"}]}],[{"t":"Plain","c":[{"t":"Str","c":"Two"}]}]]]}]]
