The 5Rs are put forward on the OpenContent website as a framework for assessing the extent to which content is open:
Retain - the right to make, own, and control copies of the content (e.g., download, duplicate, store, and manage)
Reuse - the right to use the content in a wide range of ways (e.g., in a class, in a study group, on a website, in a video)
Revise - the right to adapt, adjust, modify, or alter the content itself (e.g., translate the content into another language)
Remix - the right to combine the original or revised content with other open content to create something new (e.g., incorporate the content into a mashup)
Redistribute - the right to share copies of the original content, your revisions, or your remixes with others (e.g., give a copy of the content to a friend)[3]
This broader definition distinguishes open content from open source software, since the latter must be available for commercial use and adaptation by the public. However, it is similar to several definitions for open educational resources, which include resources under noncommercial and verbatim licenses.[5][6]
The Open Definition, which purports to define open content and open knowledge, draws heavily on the Open Source Definition; it preserves the limited sense of open content as libre content.[7]
