DIF Presentation Exchange Specification v1.0

Fellow community members,

The DIF Claims and Credentials Working Group is pleased to announce that
the Presentation Exchange Specification v1.0
<https://identity.foundation/presentation-exchange/spec/v1.0.0/#> is
now a *Working
Group Draft*. We invite you to review the specification in advance of its
transition to *Working Group Approved *status. After this period of review,
we will call for implementations as we progress toward a v1.0 Ratification
candidate.

*Abstract*

A common activity between peers in identity systems that feature the
ability to generate self-asserted and third-party issued claims is the
demand and submission of proofs from a Holder to a Verifier. This flow
implicitly requires the Holder and Verifier have a known mechanism to
facilitate the two primary steps in a proving exchange: the way Verifiers
define the proof requirements, and how Holders must encode submissions of
proof to align with those requirements.

To address these needs, this Presentation Exchange specification codifies
the Presentation Definition data format Verifiers can use to articulate
proof requirements, as well as the Presentation Submission data format
Holders can use to submit proofs in accordance with them. The specification
is designed to be both claim format and transport envelope agnostic,
meaning an implementer can use JSON Web Tokens (JWTs), Verifiable
Credentials (VCs), JWT-VCs, or any other claim format, and convey them via
Open ID Connect, DIDComm, Credential Handler API, or any other transport
envelope.

Comments on the Draft are welcome through 03:59 UTC/GMT on 2021-01-22
(23:59 Boston time on 2021-01-22) and should be provided as issues raised
on the specification's GitHub repository
<https://github.com/decentralized-identity/presentation-exchange/issues>.

Thank you,
Brent Zundel,
