1. OpenCourseWare (OCW) provides free access to educational course materials from universities around the world. OCW aims to share knowledge openly but does not grant degrees or involve direct student-teacher interaction. 2. There are different OCW models, including content-focused models by single or multiple institutions, and community-focused models where learners collaboratively create courses. 3. Institutions should choose an OCW platform and publishing process that fits their goals and infrastructure. Interoperability standards help aggregate OCW courses across different systems.
