Licenses

You choose a license when you submit. It is shown on the paper or sketch page, and it covers the content you submitted, not the records about it. Verifications, novelty checks, declarations, predictions and votes are released under CC0.

License	What it allows
CC BY 4.0, the default	Anyone may share it and build on it, with credit.
CC BY-SA 4.0	As CC BY, and work built on it carries the same license.
CC0 1.0	You place it in the public domain and keep no conditions.
CC BY-NC 4.0	Credit required, and no commercial use.

Submit only work you have the right to license this way. A version keeps the license it was admitted under, and a later version may carry a different one.

The site's code is AGPL-3.0-or-later, the specification is CC0, and dataset releases are CC BY 4.0.
