The document discusses open educational resources (OER) and the OLnet initiative for supporting OER design. It provides an overview of OER and principles of open design. The OLnet tools aim to make the design of OERs more explicit, shareable, and collaborative. Workshop participants used CompendiumLD software to visually represent and redesign the pedagogical design of a Spanish OER to make it more collaborative. The goal is to build capacity for OER reuse through representation, discussion, and refinement of design issues.
