About
Sources
Data comes from the agency that produced it, never from an aggregator. Everything ingested is listed first; everything merely planned is listed second and clearly separated, because a roadmap presented as a catalogue is a way of overstating what a site contains.

What makes a source eligible
- Published by a government body or an intergovernmental organisation.
- A stable identifier that survives between releases, or a documented crosswalk.
- A licence that permits redistribution, checked before any work starts.
- Enough measures per record to clear the completeness threshold — a source that yields a name and one number produces thin pages and is not worth ingesting.
