Difference between revisions of "CC0 use for data"

CC0 (read “CC Zero”) is a universal waiver that may be used by anyone wishing to permanently surrender the copyright and database rights they may have in a work, thereby placing it as nearly as possible into the public domain. CC0 is not a license, but a legal tool that improves on the “dedication” function of our existing, 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 is particularly relevant to data. Databases may contain facts that, in and of themselves, are not protected by copyright law. The copyright laws of some jurisdictions cover database design and structure, however, and some jurisdictions like the European Union have enacted special laws to protect databases when they are not protected under applicable copyright law. CC0 is intended to cover all copyright and database laws, so that however database rights are protected (under copyright or otherwise), those rights are all waived. 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."

Flickr published its shapefile dataset online, waiving all copyright restrictions via the CC0 public domain waiver. 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.
