Re: [dispatch] IETF 116 - do you have something for DISPATCH?

Hi Anders, 

Shall I consider that you are asking for a slot to present D-CBOR in this DISPATCH meeting? 

Best Regards, 
Shuping

We would obviously like to work with groups who might want to make use of Envelope for its privacy-preserving document format. We also think we have critical mass on the US west coast to justify a BOF there and would like to see if Dispatch would be interested in supporting that.

Because determinism is very important for the hashing that we use at the center of the Envelope format, we’ve created and released what we believe are the only reference libraries focused on dCBOR as part of our intersectional work on the topic. We’d love to get advice from Dispatch on how to work with other CBOR-focused groups who might be interested in the work we’ve done to support the deterministic subset defined in the IETF CBOR specification. (We’ve tried to contact some on our own, but we appear to getting stuck in email filters.)

The definition of a usable subset of CBOR supporting deterministic serialization would IMO qualify as a separate DISPATCH work item:

Before you do, I would not rule out
https://www.ietf.org/archive/id/draft-rundgren-cotx-04.html
which I hereby propose as a DISPATCH work item.
