Open.Michigan is the University of Michigan's contribution to the Open Education Resources (OER) project—an initiative that promotes the free and open exchange of courseware, throughout the world. After several years of using the eduCommons platform, which is built on the Zope and Plone CMSs, Open.Michigan decided it was time for an upgrade. Their goal was to build a top-notch courseware delivery system and make it freely available to the OER community. Drupal was the natural choice for this endeavor because not only is it robust and scalable, it is also open-source. Over many months, we worked very closely with the Open.Michigan team to develop a complex courseware delivery system to meet their exact specifications. Features include one-click download of all course materials, easier collaboration among university departments, and a full revision-tracking system. Since the system launched in late September, the staff at Open.Michigan have seen huge improvements in productivity. Piet Kleymeer, Open Education Manager, states, "...an improved user interface and more reliable and consistent software behavior, has cut our publishing time by nearly 400%." The system developed by Open.Michigan is available for download through github.com.
