The webinar discussed sustainability strategies for open educational resources (OER). It began with an overview of Creative Commons licensing and the 5R permissions for OER - Retain, Reuse, Revise, Remix, and Redistribute. It then explored three views of OER sustainability: Historical, focusing on early models; Contemporary, taking institutional and technical perspectives; and Business, involving developing open business models and generating revenue. The webinar concluded by soliciting participant feedback to improve OER sustainability approaches.
