UJG / Editor's Draft

Editor's Draft (ED)

The ED workspace captures the newest ideas, examples, and proposals. Documents can change at any time. You can use it for:

  • Participate in discussions and contribute.
  • Track upcoming changes while implementing.
  • Prototype the newest journey patterns.

Spec Family

Foundational UJG modules and supporting drafts that define the shared interoperability baseline.

First-Level Optional Modules

Optional modules whose dependencies are limited to the main spec family. They publish their own ontology, JSON-LD context, and SHACL artifacts without depending on other optional modules.

Second-Level Optional Modules

Optional modules that depend on one or more first-level optional modules, plus any needed main spec family modules.

Document Extensions

Optional interoperable JSON structures attached to a UJGDocument. They do not participate directly in the UJG RDF graph and may use their own validation mechanisms.
