The University of Twente has an overall data policy (pdf) on how to handle research data. This policy serves as a starting point for tailored data policies of faculties and/or institutes, and research groups.
Data policies explicitly state the responsibilities and authority within the group. They also state how group members should in principle collect, describe, save and share their data during and after their research.
For guidance in creating your group’s data policy, please contact your information specialist.
