The purpose of Creative Commons licenses is to help creators legally share their knowledge and professional activities to drive a new era of development. By offering free and easy-to-use licensing, it helped create a simple and standardized way to allow the public to make use of the work of diverse artists, photographers, illustrators and designers without, however, compromising copyright.
Creative Commons is based on the Copyright Law in force, being just an extension of the same that aims to promote the sharing of knowledge and creativity as a form of social transformation.
