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."
CC0 use cases
This is a list of uses of CC0 for data and databases. For uses of CC licenses, see Data and CC Licenses.
The British Library released a large set of their bibliographic data into the public domain via the CC0 public domain dedication. This set is from the British National Bibliography, which contains data on publishing activity from the United Kingdom and the Republic of Ireland since 1950, and comprises 20% of the entire British Library catalog. The dataset currently consists of 3 million individual records.
CERN, the European Organization for Nuclear Research that is home to the Large Hadron Collider and birthplace of the web, released its book catalog into the public domain using the CC0 public domain dedication.
All bibliographic data from Cologne-based libraries are available to the public with no known copyright restrictions. Cologne-based libraries who surrendered their copyrights using the CC0 public domain dedication include the University and Public Library of Cologne (USB), the Library of the Academy of Media Arts Cologne, the University Library of the University of Applied Science of Cologne, and the LBZ. The data is currently linked from the North Rhine-Westphalian Library Service Center (hbz). For more info, see the blog post.
All content on Digg, a social news website, is defaulted under CC0, which means that Digg has surrendered all copyrights to its content. Content includes readers' comments, story titles, story descriptions, and all of the other user-contributed content on the Digg site. For more info, see the blog post.
Dryad is an online repository for data contained in academic papers and other publications in the sciences. The National Evolutionary Synthesis Center and the University of North Carolina Metadata Research Center, in partnership with various journals and societies, comprise the development of Dryad's data set, all of which is released under the CC0 public domain dedication.
Europeana — Europe’s digital library, museum and archive, and the first major adopter of the Public Domain Mark — has adopted a new Data Exchange Agreement which releases metadata for millions of cultural works into the public domain using the CC0 public domain dedication.
Flickr published its shapefile dataset online, surrendering all copyrights via the CC0 public domain dedication. A shapefile is a file containing shapes mathematically generated by thousands of Flickr geotagged photos of particular neighborhoods, countries, and continents. Shapefile data has been used to reverse-engineer maps with user generated longitude and latitude coordinates that are then demarcated by Where-On-Earth IDs, "unique numeric identifiers that correspond to the hierarchy of places where a photo was taken: the neighbourhood, the town, the county, and so on up to the continent." For more information, see the blog post.
Genomes Unzipped is a project that aims to inform the public about genetics via the independent analysis of open genetic data, volunteered by a core group of genetics researchers and specialists. Genomes Unzipped genetic data is available in the public domain via the CC0 public domain dedication, while other site content is defaulted under CC BY-SA.
The German Wikipedia uses CC0 to dedicate data into the public domain; specifically, their PND-BEACON files are available for download. Since Wikipedia links out to quite a number of external resources, and since a lot of articles link to the same external resources, PND-BEACON files are the German Wikipedia’s way of organizing the various data.
One of the leading pharmaceutical companies in the world, GlaxoSmithKline has surrendered all copyrights in its malarial data set via CC0, which includes more than 13,500 compounds known to be active against malaria.

The Piemonte Region is leading the open data movement in Italy at the government level, being the only regional government to open up all its data for reuse without restrictions.
Using CC0, MichiganView has surrendered all copyrights to its 93+ Gigabytes of Landsat 5 and 7, and NAIP imagery data. The MichiganView consortium makes available aerial photography and satellite imagery of Michigan to the public for free over the Web. As part of the AmericaView consortium, MichiganView supports access and use of these imagery collections through education, workforce development, and research. For more info, see the blog post.
The Netherlands government launched www.rijksoverheid.nl, a single website for all Dutch ministries, in March 2010. The default copyright policy for site content is that there is no copyright; using the CC0 public domain dedication, the government surrendered all copyrights in site.
