What is in it

Each fact is a claim: an entity, a predicate and a value or another entity, with its source and when we fetched it. Only public claims are included; data we hold but cannot republish is not in the file, not even its label. Coordinates from OpenStreetMap Nominatim geocoder (39 entities) are left out: their licence is share-alike. The entity pages show them, with their credit.

The same claims, per source and as JSON Lines, are on each source page.

Licence

Each claim keeps the licence of its source, named in its source_id. Every source in the file allows republishing: it is public domain or CC0, or it asks for a credit line (CC BY 4.0 and open government licences). Reuse the data under each source's licence, and credit each source whose data you use with its line in the list below and in sources.csv.

How to cite
