I think we're OK with backwards compatibility, because the JSON header
extension would be a "header extension" in this sense:

https://nifti.nimh.nih.gov/nifti-1/documentation/faq#Q21

Any compatible NIfTI1 reader should happily skip over the header
extension data it does not recognize - and I think that's true of the
major packages.

As for the review process, that's what we're doing in these
discussions - I drafted up a spec a while ago, that is here:

https://github.com/nipy/nibabel/wiki/json-header-extension

That was the first pass.  See this thread for the initial discussion:

https://mail.scipy.org/pipermail/nipy-devel/2014-July/010087.html

I'm just in the process of finishing up a second pass. When I've done
that, and we've done another pass at discussion here, I'll email out
to the AFNI / SPM / FSL mailing lists to see if they've got any
thoughts.   Can you think of anywhere else the discussion should go?

Cheers,

Matthew
