With the support of The William and Flora Hewlett Foundation, ccLearn surveyed the copyright licensing policies of several hundred educational projects or organizations on the Internet to assess whether these legal conditions limit the usefulness of self-designated open resources from the user's perspective.
The study reveals three principal findings:
- The majority of OER projects or organizations have adopted a standardized license created by an independent license provider, and of these, the large majority have adopted one or more of the six Creative Commons copyright licenses ("CC licenses") to define the terms of openness. But, a sizable minority of OER providers have chosen to craft their own license -- often borrowing terms from one of the standardized licenses. Thus, as a group, OER providers have adopted a diverse, and often customized, set of license conditions that in some cases require significant work by users to understand;
- The usefulness of OERs as a group is limited by incompatible license conditions that functionally prohibit combination or adaptation of OERs provided by different sources.
