This permissive licensing is the minimum requirement for OER. What is the "much more" that I was referring to? What more can we do to increase the value of OER, both for the educational community and for the producers of the content?
And value from which perspective? OER presents different value propositions to educational institutions that consume them, students that consume them, educational institutions that produce them, and companies that produce them. And perhaps the most important value proposition, and definitely the least appreciated, the value to the student who produces content.
Most of an iceberg is hidden under the surface.
