The Open Educational Resource concept was proposed several years ago as a way to develop the Open Movement principles in the educational domain. Despite the open and participative view underlying this proposal, there has not been a significant adoption of this concept by users. Many problems and barriers have been considered and analyzed. Nevertheless, we consider that a main issue is the contradiction among the definitions proposed and the real support provided by platforms. In addition, there exist also different approaches to the concept by users and organizations. In this paper we call for a real open approach to the Open Educational Resource concept and introduce a platform where specific functionalities have been introduced to support its development.
