Publishing model

UJG evolves in the Editor's Draft workspace. Technical Reports are immutable snapshots of documents the editors believe are reliable enough for community experimentation.

  • Selected draft material captured at a point in time.
  • Stable URL space for implementers.
  • Publication does not mean every included part is final or stable.
  • ED continues iterating alongside TR releases.
