Week 4 Creative Commons

I am writing this week about creative commons, it is a non profit organization. They offer copyrights for the online world.
Basically for artist who want to get there stuff out there but also retain some rights.
They offer various forms of copyrights.

NonCommercial - A non-commercial license lets others copy, distribute, perform creative works and derivative works, but only for noncommercial purposes (anyone using the creative works cannot profit from it).

ShareAlike - A ShareAlike license allows others to distribute derivative works under a license identical to the one held by the original copyright holder.

NoDerivative Works - A NoDerivative Works clause allows others to copy, distribute, display and perform the exact copywritten works and no derivative works can be created.

Attribution - An Attribution license means creative works can be copied, distributed, displayed, or performed and derivative works can be created, provided that appropriate credit to the original copyright holder is given.
