OpenCourseWare (OCW) provides free access to educational materials from universities organized as courses without credits or interaction. OCW began at MIT in 2001 to share course materials worldwide and provide a model for other schools. An OCW contains learning materials from existing high-quality courses but is not meant for degrees. There are different OCW models, including content-focused models from single or multiple institutions and community-focused models involving individual contributions. When creating an OCW site, considerations include technology platforms, existing systems, publication processes, users, and budgets. Interoperability and translations are also important.
