## Status
Provisional

## Applications/Protocols That Use This Scheme

## Scheme Syntax
The mdoc-openid4vp scheme follows the syntax:

mdoc-openid4vp://<authorization-request>
<authorization-request>: The OID4VP Authorization Request as defined in Annex B of ISO/IEC 18013-7:2024.

Example:
mdoc-openid4vp://?client_id=example.com  &request_uri=https%3A%2F%2Fexample.com%2F567545564

## Encoding Considerations
The scheme uses UTF-8 encoding.
Query parameters follow percent-encoding as per RFC 3986.

## Intended Usage
The mdoc-openid4vp scheme is intended for online presentation of digital credentials in the ISO/IEC 18013-5:2021 format over the internet.

## Interoperability Considerations
Aligns with ISO/IEC 18013-5 for mDL and ISO/IEC 23220-4 mdoc data exchanges.
Compatible with OpenID Connect for Verifiable Presentations (OID4VP).
Works with mobile operating systems and identity wallets that support custom URL schemes.
