What common creative licenses do?

The Creative Commons copyright licenses create a balance within the traditional "All Rights Reserved" environment that results from copyright. Our tools give anyone, from individual authors to large companies and institutions, a simple, standardized method of giving copyright permissions to their works. The combination of our tools and their users is a large and growing digital commons , a pool of content that can be reproduced, distributed, modified and incorporated into new works , all within the framework of existing copyright.
The terms of use for datasets of the federal authorities on are determined by the existing legal framework. If there is a statutory requirement to cite the source, this is indicated by the appropriate licence name/typ next to the dataset concerned. In all other cases, users are recommended to cite the source.


CC0 enables scientists, educators, artists and other creators and owners of copyright- or database-protected content to waive those interests in their works and thereby place them as completely as possible in the public domain, so that others may freely build upon, enhance and reuse the works for any purposes without restriction under copyright or database law.

CC BY 4.0

All CC licenses require that others who use your work in any way must give you credit the way you request, but not in a way that suggests you endorse them or their use. If they want to use your work without giving you credit or for endorsement purposes, they must get your permission first.

CC BY-SA 4.0

This license allows others to distribute, remix, enhance and build upon your work, including commercially, as long as you are named as the originator of the work and the new works based on your work are published under the same terms. This license is often compared to "copyleft" free and open source software licenses. All new works that are based on your will be under the same license and therefore be commercially usable. This is the license that is also used by Wikipedia, recommended for works for which the inclusion of Wikipedia material or other licensed works may be useful.


This license permits others to redistribute their work, both commercially and non-commercially, as long as it is done without modification and complete and you are the author.
