Creative Commons Zero (CC0 1.0)

CC0 is the Creative Commons equivalent for non-code works (data, documentation, assets). It is a public domain dedication with a fallback permissive license for jurisdictions that do not recognize public domain dedications.

The full legal text is available at https://creativecommons.org/publicdomain/zero/1.0/legalcode.

What this means

Both the Unlicense and CC0 waive all copyright interest. There are:

• No attribution requirements
• No copyleft obligations
• No restrictions on use, modification, or redistribution
• No patent grants (unlike Apache-2.0)

Where this applies

Public domain dedications are used for:

• Utility code snippets and boilerplate
• Data files, lookup tables, and configuration templates
• Sample code and educational examples
• Assets explicitly donated to the public domain by contributors
