Cc0 88x31.png

CC0 (read “CC Zero”) is a universal public domain dedication that may be used by anyone wishing to permanently surrender the copyright and database rights (where they exist) they may have in a work, thereby placing it as nearly as possible into the public domain. CC0 is a legal tool that improves on the “dedication” function of our earlier, U.S.-centric public domain dedication and certification. CC0 is universal in form and may be used throughout the world for any kind of content without adaptation to account for laws in different jurisdictions. And like our licenses, CC0 has the benefit of being expressed in three ways – legal code, a human readable deed, and machine-readable code that allows works distributed under CC0 to be easily found.

CC0 can be particularly important for the sharing of data and databases, since it otherwise may be unclear whether highly factual data and databases are restricted by copyright or other rights. Databases may contain facts that, in and of themselves, are not protected by copyright law. However, the copyright laws of many jurisdictions cover creatively selected or arranged compilations of facts and creative database design and structure, and some jurisdictions like those in the European Union have enacted additional sui generis laws that restrict uses of databases without regard for applicable copyright law. CC0 is intended to cover all copyright and database rights, so that however data and databases are restricted (under copyright or otherwise), those rights are all surrendered. CC0 is also particularly relevant to scientific data. An opinion piece in Nature on "Post-publication sharing of data and tools" explicitly recommends open sharing and the use of CC0 to put data in the public domain:

"Although it is usual practice for major public databases to make data freely available to access and use, any restrictions on use should be strongly resisted and we endorse explicit encouragement of open sharing, for example under the newly available CC0 public domain waiver of Creative Commons."

European Union

The European Commission released licensing recommendations to support the reuse of public sector information in Europe. In addition to providing guidance on baseline license principles for public sector content and data, the guidelines suggest that Member States should adopt standardized open licenses – such as Creative Commons licenses. "Open standard licences, for example the most recent Creative Commons (CC) licences (version 4.0), could allow the re-use of PSI without the need to develop and update custom-made licences at national or sub-national level. Of these, the CC0 public domain dedication is of particular interest. As a legal tool that allows waiving copyright and database rights on PSI, it ensures full flexibility for re-users and reduces the complications associated with handling numerous licences, with possibly conflicting provisions."

Europeana
