From Creative Commons Australia who created the flowchart:
A number of copyight experts, most notably Professor Lawrence Lessig of Harvard University, frustrated by the fact that technology offered so much but that negotiability of copyright material was so cumbersome, came up with the idea of the Creative Commons. Lessig’s vision was for a space in the internet world where people could share and reuse copyright material without fear of being sued – a creative commons. To create this, copyright owners would use a generic licence to give permission in advance for certain uses of their material. Rather than the ‘all rights reserved’ of traditional copyright law, Lessig aimed to create a voluntary ‘some rights reserved’ system.
Creative Commons is now a worldwide project that encourages copyright owners to allow others to share, reuse and remix their material, legally. We offer a range of licences that creators can use to manage their copyright in the online environment, each offering its own specific protections and freedoms. We have built upon the “all rights reserved” of traditional copyright to create a voluntary “some rights reserved” system.
Creative Commons are a nonprofit. All of the tools, internationally, are free.
