Jan: Test requirements for the EU -> sync separately with Oliver
Paul: Redirect URI in VCI

# Notes

## DICE: In-person DCP WG meeting

https://dcp-wg-pre-dice_22june26.eventbrite.co.uk/
Yet to be determined if this is going to go ahead based on the interest of people.

## OIDF Conformance Team calls all implementers to test the VCI/VP tests

Internal OIDF rules require 3 successful vendor implementations for all tests
Implementations should test with at least 5.1.44 (some implementations tested with earlier versions).

Positive Test Results so far:
- VCI issuer: 3 results for sd-jwt, none for mdoc
- VCI wallet: 3 results for sd-jwt, none for mdoc
- VP wallet: not great, 2 sd-jwt, 1 mdoc
- VP verifier: probably okay, 2 mdl, 4 sd-jwt,

Implementers requested for the missing areas (especially mdoc)!

DC API for wallets is available, but no passing tests yet. Maybe because everyone is relying on the Android matcher which doesn’t support HAIP requirements

Thomas’ question to the DCP WG is if certification should wait for DC API support or go ahead.
Gareth said he could potentially give feedback about the updated matcher next week.

Gail said OIDF will use its good judgement to see how and when it would go ahead unless there is strong feedback to not do so. Going ahead is also required to meet other deadlines with the EU commission.

## OpenID4VCI

Add redirect_uri to (Deferred) Credential (Error) Response to continue interaction with end user
https://github.com/openid/OpenID4VCI/pull/723

Discussion between Gareth and Paul on the options described in the issue.
Paul is asking Gareth to provide some more content to help reviewers understand what the consequences are with different directions.

General direction IAE
Paul mentioned that the direction is to create a profile based on first party apps draft.
As such we should first complete PR 736, before continuing with the other topics.

Add redirect_uri to (Deferred) Credential (Error) Response to continue interaction with end user
https://github.com/openid/OpenID4VCI/pull/736

Based on the discussion the group recommends to change naming to `auth_via_web`.

Metadata in credential response
https://github.com/openid/OpenID4VCI/pull/721

PR has enough reviews. Merging.

Rephrase conditions to provide nonce in proof types based on presence of Nonce endpoint
https://github.com/openid/OpenID4VCI/pull/678

Oliver to look at review from Andreea
Joseph to review the PR and see if his concerns are addressed

Add credential dataset identifier
https://github.com/openid/OpenID4VCI/pull/472

Oliver to look at resolving any merge issues before next call.

Discussion on Paul’s questions
- Agreement to make the param mandatory
- The param is a string (the case in the PR)

Oliver to add changes and then Paul will review.
