There are a number of CC licenses available to protect you as you create, share, and use content. Please review the following site for more details. For more information on how to easily set up a CC license and add it to your page, please click here. There are six main levels of CC licensing.
Attribution
All Creative Commons Licenses require attribution, or giving credit to the author or licensor. In CC licensing, the author technically chooses how this attribution should be applied. Usually authors do not specify a specific way. As a result, an attribution should include: the name of the author and/or licensor; the title of the work (if available); and the URL that is associated with the work. This attribution may be included just beneath the content, or in a footnote. There is a great deal of "good faith" in the specifications indicated here. Finally, this attribution should not indicate any form of endorsement by the author, or licensor.
A Link to the License
All CC Licenses require a copy of the license, or a URL link to the license. Failure to do so means that you did not complete the terms of the CC license.
Commercial Use
Some CC licenses do not allow commercial use. If your use would be considered commercial, you need to make sure that your use complies with that element of the license. Creative Commons defines a commercial use as that, in “any manner that is primarily intended for or directed toward commercial advantage or private monetary compensation.” There is a lot of gray area in what is considered commercial use, and what is not. It is advised that if you feel your use in any way meets the definition above, you should probably avoid using the work if the license requires non-commercial use. If you have any questions about a specific situation ask the author or licensor directly.
Derivative Work
A Creative Commons defines a derivative work as “a work based upon the Work or upon the Work and other pre-existing works, such as a translation, musical arrangement… or any other form in which the Work may be recast, transformed, or adapted.” If any time you modify CC licensed work to create another work (e.g., translate it, rewrite it, remix it) it is considered a derivative under the license and you need to make sure you have permission in order to do that.
You do not need this permission to copy and paste a work into your site as that is considered a “Collective Work”, similar to a periodical. You are allowed to modify the work as far as is “technically necessary to exercise the rights in other media and formats”. This would include things such as converting a movie to another type to upload it to YouTube. But beyond those necessary changes, the work must remain intact and separate from other works.
Share Alike
Many sites that do allow derivative works to be created add an additional stipulation, known as the share-alike requirement. This requirement stipulates that the new work be placed under the same terms. These licenses prevent reusers from making derivative works from a CC-licensed work and then locking the new creation away (at least the parts that can be separated from the original). This only affects derivative uses of the work, not ones that keep the original completely intact and do not build or recreate it. This ensures that the new content that is added to the original is licensed the same as the original. If you use a share-alike work in a derivative manner, you have to both complete the terms of the original license (attribution, link to license, etc.) and you have to license the new work under the same terms..
