In a "User-Centric Request Model", a presentation is a signed request that includes a Scope (of processing) and a Purpose (of processing) related to a real-world transaction. In a zero-trust architecture, the signer of the request is held accountable. VP Exchange, VP Request, OIDC4VP seem to be intended as components of a user-centric (authorization) request. From my perspective, standardizing the authorization request and the processing capability outcome are essential to interoperability. Standardizing the subsidiary protocols is useful, of course, but only to the extent they are not competing with other ways of doing exchange, authentication, or prompting for what is needed to process a transaction. - Adrian On Wed, Jun 29, 2022 at 2:03 PM Dmitri Zagidulin <dzagidulin@gmail.com> wrote: > 'Verifiable Presentation' is a data model.
