Works free of copyright restrictions, available for anyone to use without permission.
DESCRIPTION
The public domain comprises creative works without exclusive intellectual property rights. Materials may enter via expiration, dedication (e.g., CC0), or ineligibility. Public domain content is reusable without permission, though attribution and ethical use remain good practice. For AI, public domain sources reduce legal risk in training datasets. Organizations should verify status and jurisdictional differences.
