View source for 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, [http://creativecommons.org/licenses/publicdomain/ 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.

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" (http://code.flickr.com/blog/2008/10/30/the-shape-of-alpha/).
