Creators and copyright holders who wish to apply a Creative Commons license to their work can choose to allow their work to be copied and reused with any one or more restrictions, or certain combinations of restrictions. The four restrictions are:
|Attribution||You must give appropriate credit, provide a link to the license, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.|
|Non Commercial||If you remix, transform, or build upon the material, you may not distribute the modified material.|
|Share Alike||If you remix, transform, or build upon the material, you must distribute your contributions under the same license as the original.|
|No Derivatives||If you remix, transform, or build upon the material, you may not distribute the modified material.
It is important to consider how you want to use the work. For example, if you need to make changes, then an "ND" license won't help you.
The four license conditions described above can be combined to make specific licenses. The six license types are summarized in the chart below.
|This license lets others distribute, remix, tweak, and build upon the work, even commercially, as long as they credit the creator for the original creation. This is the most flexible and accommodating of the available Creative Commons licenses. Recommended for maximum dissemination and use of licensed materials.|
|This license allows for redistribution, commercial and non-commercial, as long as the licensed work is passed along unchanged and in whole, with credit to the creator.|
|This license lets others remix, tweak, and build upon the work non-commercially, and although their new works must also acknowledge the creator and be non-commercial, they don’t have to license their derivative works on the same terms.|
|This license lets others remix, tweak, and build upon the work even for commercial purposes, as long as they credit the creator and license all new creations under the identical terms. This license is often compared to “copyleft” free and open source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use. This is the license used by Wikipedia, and is recommended for materials that would benefit from incorporating content from Wikipedia and similarly licensed projects.|
|This license lets others remix, tweak, and build upon your work non-commercially, as long as they credit the creator and license their new creations under the identical terms.|
|This license is the most restrictive of the six main licenses, only allowing others to download your works and share them with others as long as they credit the creator, but they can’t change them in any way or use them commercially.|
