The following may be of interest and could possibly also affect the charter.

As you know (?) signing JSON is currently only standardized [1] through encoding JSON data in Base64Url.
I find that pretty incompatible with business systems' requirements and started a quest a few years ago to see if there could be an alternative.

After carefully testing and evaluating three completely different approaches I consider that done:
https://tools.ietf.org/html/draft-rundgren-json-canonicalization-scheme-02
However, this proposal will most likely never become an IETF standard unless another and credible party like the W3C shows interest.  Naturally you would in that case need to evaluate the proposal first.

You may test the scheme using an on-line service: https://mobilepki.org/jws-jcs/home

I'm not aware of any other mature alternative to these two roads to signed JSON.

Note that the proposal above is 100% compatible with both JWS [1] and existing JSON tools.

Thanx,
Anders
