[Openid-dcp] [Openid-specs-fapi] EU Payment Wallet Standard(s) - Proposed W3C Community Group

[steffen schwalm]

Hi all,

thanks a lot for your initiative Anders. Since Large Scale Pilots on EUDI
already work on the subject I strongly recommend alignment with them (since
you Anders are as far as I know mit participate there). Since it's possibly
related to Digital Credentials WG in OIDF also alignment there seems
meaningful (possibly this might be better place for the standardization
than W3C (

As there's work already ongoing in different SDO we should avoid double
work and explore this first.

Thx & Best
Steffen
