In the beginning of 2013 Delft University of Technology joined the EdX Consortium. One of the important reason to join EdX was the intended openness. Immediately Delft took the first step to announce that the DelftX MOOCs will have an open-license (CC-BY-NC-SA). EdX took the next step with open-sourcing the platform. In June the code will be made available via github. The release of the source code marks the first step toward edX's vision of creating an open online learning platform that mirrors the collaborative philosophy of MOOCs themselves and is an invitation to the global community of developers to work with edX to deliver the world's best and most accessible online learning experience. In this presentation I will go into more details about the open-licensed courses and the open-sourced platform.
