[Cbor] New CDE drafts

[Carsten Bormann <[e-mail]>]

The recent discussion on the mailing list reminds me that a document that defines a CDE seems to be required more than ever.  I separated out CDE from my dCBOR essay, and have submitted both so we have an example of an Application Profile (see below).

I would like us to spend some time during Tuesday’s cbor WG meeting to discuss how we want to proceed in this space.  Comments on my submissions to this of course are also welcome.

Grüße, Carsten


Name:     draft-bormann-cbor-cde
Revision: 00
Title:    CBOR Common Deterministic Encoding (CDE)
Date:     2023-11-05
Status:   https://datatracker.ietf.org/doc/draft-bormann-cbor-cde/
HTML:     https://www.ietf.org/archive/id/draft-bormann-cbor-cde-00.html


Abstract:

  CBOR (STD 94, RFC 8949) defines "Deterministically Encoded CBOR" in
  its Section 4.2, providing some flexibility for application specific
  decisions.  To facilitate Deterministic Encoding to be offered as a
  selectable feature of generic encoders, the present document defines
  a CBOR Common Deterministic Encoding (CDE) Profile that can be shared
  by a large set of applications with potentially diverging detailed
  requirements.

  This document also introduces the concept of Application Profiles,
  which are layered on top of the CBOR CDE Profile and can address more
  application specific requirements.  To demonstrate how Application
  Profiles can be built on the CDE, a companion document defines the
  application profile "dCBOR".

Title:    The CDE-based Application Profile dCBOR
Date:     2023-11-05
Status:   https://datatracker.ietf.org/doc/draft-bormann-cbor-dcbor/
HTML:     https://www.ietf.org/archive/id/draft-bormann-cbor-dcbor-04.html

Abstract:

  CBOR (STD 94, RFC 8949) defines "Deterministically Encoded CBOR" in
  its Section 4.2, providing some flexibility for application specific
  decisions.  The CBOR Common Deterministic Encoding (CDE) Profile
  provides a more detail common base for Deterministic Encoding,
  facilitating it be offered as a selectable feature of generic
  encoders, as well as the concept of Application Profiles that are
  layered on top of CDE.  This document defines the application profile
  "dCBOR" as an example of such an application profile.
