CClisenssit

CClisenssit, here used as the Finnish-style rendering of Creative Commons licenses, constitute a family of copyright licenses that allow creators to grant the public permission to use their works under clearly defined terms. They are designed to facilitate sharing and remixing while preserving the rights of the original author.

Developed by the non-profit organization Creative Commons, the licenses were first released in 2002 and have since become widely adopted across education, science, media, and government. The current mainstream framework is version 4.0, which provides a harmonized, global standard and is designed to be compatible with international copyright laws.

Each license expresses a combination of four conditions: Attribution (requiring credit to the creator), NonCommercial (allowing use only for non-commercial purposes), NoDerivatives (prohibiting adaptations), and ShareAlike (requiring derivatives to be licensed under the same terms). The licenses range from CC BY (most permissive) to CC BY-NC-ND (most restrictive), with several intermediate forms such as CC BY-SA and CC BY-NC-SA. In addition, CC0 allows a work to be dedicated to the public domain.

Usage involves a creator selecting a license and attaching it to the work. Users may reuse, modify, or distribute the work in line with the chosen terms. The licenses are irrevocable for existing copies, provided the terms are followed. They do not replace copyright; they grant permissions under the author’s chosen conditions and are separate from public-domain designations that waive all rights.

Impact and reception: CC licenses are widely used by educators, researchers, publishers, and cultural institutions to promote access and collaboration while maintaining authorship and liability protections.
