(registered 2026-07-01, last updated 2026-07-01) ## URI Scheme Name mdoc-openid4vp ## Status Provisional ## Applications/Protocols That Use This Scheme The mdoc-openid4vp scheme is used to initiate OpenID for Verifiable Presentations (OID4VP) workflows as defined in ISO/IEC 18013-7:2024 Annex B involving the presentment of ISO/IEC mdoc-based credentials, including use cases based on ISO/IEC 18013-7:2024 (mobile driving licences) and other document types supported by the ISO/IEC 23220 series. ## Contact https://www.iso.org/committee/45144.html ## Author/Change Controller Same as Contact. ## Specification Document The scheme is proposed as part of Annex B in ISO/IEC 18013-7:2024. Reference: https://www.iso.org/standard/82772.html ## Scheme Syntax The mdoc-openid4vp scheme follows the syntax: mdoc-openid4vp:// : 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. ## Related Schemes mdoc (provisional) ## Additional Information Deprecated Aliases: None References: ISO/IEC 18013-5:2021 ISO/IEC 18013-7:2024 RFC 3986: Uniform Resource Identifier (URI) Generic Syntax RFC 7595: Guidelines and Registration Procedures for URI Schemes ## Security Considerations See Section 11 of OpenID for Verifiable Presentations - draft 18, and Section 14 of OpenID for Verifiable Presentations 1.0. ## Acknowledgments This registration request was drafted based on the requirements of ISO/IEC JTC1/SC17 WG10 and OpenID Foundation.
