Content rights are considered one of the most imperative elements of complexity in content processes. These processes include the construction of the content, its selection for commercial publication, its production, diffusion, and marketing, as well as itseventual use. In addition, the processes of tracking digital rights and managing access to content based rights information are gradually more necessary. The most powerful technique to control and track such access is to combine forms and meanings to achieve persistent protection.
