[Json] Re: CBOR Cross-Platform Spec @ IETF-123

[Anders Rundgren <[e-mail]>]

It might be useful knowing that the CBOR WG (informally headed by Mr. Bormann), have rejected the entire idea creating a "JSON Challenger".

In addition, Mr. Bormann is actively supporting another (and in fact quite similar) effort [*], where the authors have concluded that in order to achieve fully deterministic encoding, you must convert floating point numbers without fractions to integers.  There is no ZERO scientific support for this idea, not to mention that it is not compatible with current CBOR practice and implementations.
