Sources and method
Provenance and review cycle
Published information keeps a record of its source.
We give priority to the pages of authorities and of officially designated operators. Automated collection flags information to examine; only human validation allows a rule version to be published.
Primary source
Each provenance links to its canonical page when a secure public address is available.
Human validation
An authorized person reviews the scope and the evidence before any publication.
Version and withdrawal
The route shows the version you are viewing and its review deadline. A withdrawn version must no longer serve as a current reference.
Published routes and provenances
No route with published provenance is available at the moment.
