Side Meeting at IETF 117, Monday 15:30-17:00, on Elision Problem Statement & Gordian Envelope

W3C Credential Community:

Shigeya Suzuki, Wolf McNally, and I will be holding a public IETF Side
Meeting on Monday, July 24, during IETF 117 in San Francisco, to discuss
drafting a Problem Statement and Areas of Work for hash-based elision and
our current Gordian Envelope Internet-Draft. If you're near SF and
interested in our new privacy-focused data format, we'd love to have you
participate. As I understand it, you don't have to be registered for IETF
117 to join us for a Side Meeting.

* Gordian Envelope (& dCBOR)
   * Monday July 24th, 15:30-17:00
   * IETF 117, Golden Gate 4 Room (seats 16)

Gordian Envelope is a structured format that allows for the hierarchical
formatting of data in a privacy-focused way. It does so by using hash-based
elision: even after data is removed, its hash remains, allowing signatures
and proofs to remain valid. The elision is entirely holder-based. This is
vitally important for use cases such as credentials or records because it
allows the subject to decide what they share while not impinging on the
validity of those credentials.

The Internet-Draft on Gordian Envelope is available here:

* https://datatracker.ietf.org/doc/draft-mcnally-envelope/

After our initial presentation at IETF 116, we were advised to prepare a
preliminary Problem Statement and Areas of Work, which we have a start on
at:

* https://hackmd.io/GqY8eZtMQQygjuAn3aj1Ow

We have not yet submitted this draft to the IETF as an Internet Draft, as
we'd like to better understand the needs of the community for
privacy-focused data, and if IETF is the appropriate standards venue.

We expect there may also be some discussion of dCBOR (Deterministic CBOR),
since that’s the foundation of Gordian Envelope, but the higher-level spec
will be the main focus of the meeting.

If you have any additional questions, let me know!

Hope to see you there!
