Problem: 

The new study regulation for medical licensing in Germany has caused significant reform of the medical curricula in Germany. At Munich University (LMU), the medical curriculum Munich (MeCuM) was introduced in 2004. More individual responsibility of the students regarding their academic goals as well as a problem-oriented thought process are essential features of the new curriculum. Through our project, an open web based platform for the design of curriculum-specific teaching and study material has become accessible to students and faculty of the MeCuM. Methods: Students created an online library in harmony with the curricular structure of the MeCuM. The technical implementation was carried out with the MediaWiki-Open-Source software. Contents can be edited from all students or faculty of the MeCuM in an anonymous or personalized manner. An online questionnaire was carried out to evaluate the project. Results: Our online library as a wiki is the first solution of this kind in medical education in Germany. The concept was implemented without technical difficulties and is linked to the official websites of LMU Munich. The website's contents were visited 417,808 times from December 2005 through June 2007. Online-based evaluation showed that the project is positively recognized, and students are motivated to actively contribute. Discussion: The project closely reflects the academic curriculum of the MeCuM and creates additional opportunities for interaction between students and teachers. The design as an open source project allows easy handling as well as high control and ability to update the contents, but integrity and accuracy of the data content require further effort. Further evaluation will be essential for improvements. The integration of faculty as reviewers and tutors is planned. Sustainability of the project is dependent upon continued student leadership. Other medical faculties are interested in this concept.
