Responsible data management is part of good research, and an important prerequisite for Open Science. To promote the practice of Open Science, and the principles of FAIR data and software, the Netherlands eScience Center actively participates in the National Platform Open Science. In line with this initiative, the eScience Center strives to make the research data collected or generated in the projects it participates in to become freely and sustainably available, as much as possible, for reuse by other researchers. Furthermore, the Netherlands eScience Center aims to raise awareness among researchers that responsible data management is an essential requirement for reproducibility of scientific results, and for enhancement of the correctness and transparency thereof.
