The document discusses Creative Commons licenses and how they allow creators to open up their educational resources by choosing certain copyright permissions. It explains that openness increases with the permissions granted, and that open resources enable access to high-quality information, updates, localization/customization, and feedback loops. Creative Commons licenses work globally by letting creators change "All Rights Reserved" copyright to "Some Rights Reserved" and choose which freedoms they want their works to automatically carry without requiring permission. There are six CC license options that combine four basic elements of attribution, non-commercial use, no derivatives, and share alike conditions.
