"Creative Commons helps you legally share your knowledge and creativity to build a more equitable, accessible, and innovative world. We unlock the full potential of the internet to drive a new era of development, growth and productivity.
With a network of staff, board, and affiliates around the world, Creative Commons provides free, easy-to-use copyright licenses to make a simple and standardized way to give the public permission to share and use your creative work–on conditions of your choice."
These are the most prominently used licenses of their type in the world.
The ND and SA components cannot be combined, as SA only applies to derivative works.
