During April 2025, Zeuthen enhanced the openid/OpenID4VCI repository by clarifying the credential claim format within Credential Responses for ISO mdoc. Focusing on documentation, Zeuthen used Markdown to remove redundant language and refine the description of the base64url-encoded IssuerSigned representation, making it more concise and accurate. This update improved interoperability between issuers and verifiers by reducing ambiguity and aligning the documentation with ISO mdoc standards. Although no bugs were fixed during this period, the work demonstrated careful attention to specification alignment and documentation clarity, resulting in more precise integration guidance for developers working with OpenID4VCI and related credential technologies.
