Sources & attribution

Optikos organises its data into 0 intelligence layers. Each layer is built on a specific upstream public dataset, and each dataset carries its own license + attribution requirements. This page lists every source we redistribute, the license under which we redistribute it, and the credit each licensor requires.

If you redistribute observations or events sourced via Optikos, you must comply with the upstream licensor's attribution terms. The license identifier next to each entry is the canonical shorthand; click through to the homepage for the full text.
