There are several types of CC licenses, each offering different levels of permissions. The most common licenses are:
CC BY (Attribution): Allows others to distribute, remix, adapt, and build upon the work, even commercially, as long as they credit the author for the original creation.
CC BY-SA (Attribution-ShareAlike): Similar to CC BY, but new creations must carry the same license, allowing for commercial use.
CC BY-ND (Attribution-NoDerivs): Allows for redistribution, commercial and non-commercial, as long as it is passed along unchanged and in whole, with credit to the author.
CC BY-NC (Attribution-NonCommercial): Allows others to remix, adapt, and build upon the work non-commercially, and although new works must also acknowledge the author and be non-commercial, they don’t have to be licensed on the same terms.
CC BY-NC-SA (Attribution-NonCommercial-ShareAlike): Allows others to remix, adapt, and build upon the work non-commercially, as long as they credit the author and license their new creations under the identical terms.
CC BY-NC-ND (Attribution-NonCommercial-NoDerivs): The most restrictive license, allowing others to download the works and share them with others as long as they credit the author, but they can’t change them in any way or use them commercially.
