Re: Binding an iso mDL to VC ecosystem for online verification

I suggest you join one of these calls ( check for the one friendliest to
your timezone ) :

https://github.com/WICG/digital-identities

See also: https://www.identitycredential.dev/

And the recent comments on:
https://github.com/w3c/strategy/issues/450#issuecomment-2062897495

There's been discussion of potential browser APIs to enable the
presentation of a mDoc credential to prove age verification, possible
integration between OIDC4VP and credential management APIs, etc...

Most of the joining of credential formats I have seen, has been proposed at
the OIDC4VP layer, where a verifier website might ask for an mDoc and a W3C
JSON-LD VC, and an OAUTH JWT VC, etc...

Imagine a verifier wanted remote presentation of a credential from a mobile
wallet to a verifier website using a mobile web browser... or cross device
to a desktop web browser.

Would it be possible for the verifier to request a specific credential,
specific claims in a credential, specific credential formats, such as by
media type?

On one side the problem is mobile OS / browser APIs (holder software), on
the other side is credential query / presentation exchange formats
(verifier supported protocols).

It's a difficult problem, with lots of important privacy, security,
diversity and interoperability challenges.

Regards,

OS
