Jan Vereecken contributed to the openid/OpenID4VCI repository by enhancing documentation quality and standardization over a two-month period. He led a terminology update, renaming “Cryptographic Holder Binding” to “Cryptographic Key Binding” throughout the specification, ensuring consistent language and clearer definitions for implementers. Jan also authored new guidance for the Credential Endpoint, clarifying revocation practices to prevent unnecessary credential invalidation and reduce operational overhead for wallet developers. His work relied on Markdown for technical writing and Git-based change management, demonstrating a strong focus on documentation standards and terminology governance. These improvements supported better onboarding and interoperability for the developer community.
