 Make, own, and control copies of the content

Adapt, adjust, modify, or alter the content itself
(e.g., translate the content into another language)


Combine the original or revise content with other open content to create something new
(e.g., incorporate the content into a mashup)


Share copies of the original content, your revisions, or your remixes with others
(e.g., give a copy of the content to a friend)

This key is meant to provide an at-a-glance overview of a collection's openness. Be sure to read and understand the license for each OER you choose to use.
