Schema
Roadmap
We generally plan updates and releases by quarter, giving contributors and adopters a rough idea of what’s coming next.
Our next focus in 2026 is finalising the schema. Later will work on people travelling together (e.g. families or groups) & profile request standards.
We will update here (this page) when we have more information to share.
