The paper will describe a federate ecosystem for OER using the example of the German educational system, where a variety of ROERs (Muuß-Merholz & Schaumburg, 2014) and reference platforms have been established over the past years. In order to develop this ecosystem not only metadata standards are necessary, but also open APIs to exchange information. In conclusion, it is essential that all relevant stakeholders agree on one transparent policy that they develop collaboratively. A metadata exchange service can act as the connector of all partners.
