Open informational ecosystems play a crucial role in fostering open educational resources (OER) and allow new opportunities to share and collaborate in the learning and teaching environment. Such ecosystems containing interoperable infrastructures and open interfaces aim at fulfilling user needs and fostering practices related to the concept of OER and the five user rights (5 R's). To fully embrace this role, those ecosystems need to be designed carefully. In this paper, we discuss implications for open informational ecosystems to fully comprise the concept of OER and related user needs. We carried out literature reviews to analyse recent aspects of the 5 R's in relation to user behaviour and infrastructures. We will introduce the results from these reviews and illustrate upcoming questions and challenges for the design of an ecosystem respecting the 5 R's conceptual ideas. With our recommendations, we aim at contributing to a better understanding of the concept of OER to improve ecosystem development and implement useful and user-friendly functions.
