This page lists those licenses which have been approved by Creative Commons as guaranteeing the same freedoms as one of the Creative Commons licenses (listed below) and, as a result, Creative Commons has approved that license as compatible with the specified Creative
Creative Commons approves licenses as compatible when they, at a minimum, contain terms that have the same purpose, meaning and effect as the key license elements of a particular Creative Commons license and when a license explicitly permits the relicensing of derivatives of works made available under that license under a particular Creative Commons license.
[Please note that to date, Creative Commons has not approved any licenses for compatibility; however, we are hopeful that we may be able to do so in the future. If you would like to discuss the possible compatibility of your license with a Creative Commons license, please email us at firstname.lastname@example.org.]
