Publishing model

UJG evolves in the Editor's Draft workspace. When parts become stable they are snapshotted into a new Technical Report version.

  • Stable subset captured at a point in time.
  • Stable URL space for implementers.
  • ED continues iterating alongside TR releases.

Participate

UJG is developed openly. Feedback, issues, and implementation reports are welcome.
