[Openid-specs-digital-credentials-protocols] OIDC4VP v3

[Orie Steele]

Hello,

I'd like to repeat my proposal from today' call on this list for discussion.
I'd appreciate it if Kristina could share the link to the proposal she
presented, regarding what I am calling "PEv2", a profile of PEv1
incorporating lessons learned, and published by OIDF instead of DIF, if I
understand correctly.

It was asserted on the call today that both ISO mDoc and OAUTH JWT VC
work with "PEv1" as defined in "OpenID for Verifiable Presentations - draft
20".

If that's true, I think it's a waste of time to discuss profiling of PE
further.

Interoperability has been demonstrated, implementations exist, implementer
feedback has been gathered.

Further restricting PE based on that feedback will continue to improve
interoperability for PE based flows, but we can all see the writing on the
wall.

I don't feel the effort spent to further restrict PE is a good use of
working group call time.

Instead I propose the following:

Assign a URN to OIDC4VP draft 20 with PE JSON Schema unmodified, something
like:

"urn:ietf:params:oauth:oidc:vp:pe:v1"  request for it to be registered, and
make it clear that it is frozen effectively immediately.

"urn:ietf:params:oauth:oidc:vp:pe:v2"  request for it to be registered,
create a separate document to track "using PE moving forward", and let
people who want to contribute to that document, contribute to it... let me
know when this is, so I can avoid joining it... I have limited time to
contribute, and I would like to dedicate my time to replacing PE with
something else, not patching it until it is unrecognizable.

"urn:ietf:params:oauth:oidc:vp:w3c:v1"  request for it to be registered,
create a separate document to track "designing a format specific query
language", to be coordinated with WICG, that's basically what this document
is supposed to become, even though the first part of the document is
focused on "urn:ietf:params:oauth:oidc:vp:pe:v1" :

https://docs.google.com/document/d/1A10PZ_DviMJeyy2mDFt2QLcXUbT4O2dc_BizNXAD2PQ/edit#heading=h.txx2wxvypaci

... let me know when the call for this ^ will be so I can attend.

TLDR; Please separate the discussion of PEv1 (work completed), PEv2 (good
luck) and No PE / WICG understands the queries (I will help with this), so
that we don't see them mixed into every working group call related to
OpenID 4 VP.

Regards,

OS
