Open Educational Resources have become an integral part of adult learning in Europe. However, many issues concerning quality, legal frameworks and infrastructures remain unclear. In this context, the Federal Ministry of Education and Research provides funding for research projects on OER in Germany. An expert group coordinated by Deutscher Bildungsserver will analyse the needs for digital infrastructures (e.g. E-platforms) for OER. Wikimedia Deutschland’s project Mapping OER aims at identifying recommendations for questions like quality management, the training of practitioners or business models. First results can be expected in the beginning of 2016.
