With the increasing digitisation in research, open access is now also increasingly demanded in the field of research data. The publication of research data is intended to make another component of the scientific process openly accessible, traceable and reusable via the internet. New requirements of the funders initiated the development of organizational and technical infrastructures at the research institutions. Training and consulting on research data management and corresponding support systems are needed. Therefore, in 2020, the Vienna University of Technology, the Graz University of Technology and the University of Innsbruck started to establish institutional repositories for research data. The following contribution describes the first steps and is serves to support the establishment of further repositories, using the example of the institutional repository for research data at the University of Innsbruck based on the open-source software invenio v7.0.
