Creative Commons (CC) licences is a copyright licence that provide a standardised route for creators of content to grant permissions to others to use their creative work. They are designed to ensure creators retain copyright ownership while allowing others to copy, distribute and make use of that work with or without constraints determined by the specific licence applied. They don’t impinge on freedoms granted under the law to users of creative works otherwise protected by copyright (for example ‘fair dealing’).
While each Creative Commons licence is underpinned by a legal description, they are also presented in both a user friendly ‘human-readable’ form, and are designed to be machine-readable.
There are 4 ‘building blocks’ to Creative Commons Licences which can be used in different combinations to grant different types of permissions and to limit the reuse. Go to Creative Commons for a full description of each licence.
The ‘building blocks’ are:
- BY – Any reuse must give credit to the original creator
- NC – Only noncommercial uses of the work are permitted
- ND – No derivatives or adaptations of the work are permitted
- SA – Adaptations must be shared under the same terms as the licence on the original work
So, for example a CC BY-NC-SA licence allows reusers to distribute, remix, adapt and build upon the original work in any medium or format for non-commercial (NC) purposes only, only so long as attribution is given to the original creator (BY) and any adaptations must also be licensed under the same terms (SA).
You may also see CC0 which is not technically a licence. It allows creators to irrevocably give up their copyright and put their work into the worldwide public domain with no conditions on reuse, including no requirement, from a copyright perspective, to cite the original creator.
Plan S requires works to be Open Access under a CC BY licence. So long as attribution is given to the original authors, it allows anyone to read, distribute, remix, adapt and build on the material in any medium or format. This includes commercial use. Providing such a permissive licence on reuse maximises the ability of other researchers and commercial entities to build on the original research. cOAlition S funders argue that this is the most efficient use of public funds for both the progress of research and economic growth.
