The term “open data” refers to information that has been made technically and legally available for reuse. In our research, we focus on the particular case of open research data. We conducted a literature review in order to determine what are the motivations to release open research data and what are the issues related to the development of open research data. Our research allowed to identify seven motivations for researchers to open research data and discuss seven issues. The paper highlights the lack of dedicated data infrastructure and the need for developing the researcher’s ability to animate online communities.
