Creative Commons Zero-ShareAlike 2.0 Univiral License (CC0-SA)

Abstract

The Creative Commons licensing system is designed to be composable, and yet the public-domain-equivalent license Creative Commons Zero is deliberately set apart as a special case. Perhaps this seems obvious because a work released into the public domain must be unfettered from copyright restriction. But why can't a work released into the public domain create more public domain works? To that end, this piece is a speculative Creative Commons license that grafts their ShareAlike stipulation onto Creative Commons Zero, creating a near-public-domain license that intends to actively compel the expansion of the public domain. This copyright license endorses any and all forms of derivative uses, including explicitly the likes of plagiarism and prestidigitation. Its only requirement is that the derivative work must, itself, be licensed under CC0-SA.
