We present the approach to Research Data Management (RDM) support for researchers taken at ETH Zurich. Overall requirements are governed by institutional guidelines for Research Integrity, funders’ regulations, and legal obligations. The ETH approach is based on the distinction of three phases along the research data life-cycle: 1. Data Management Planning; 2. Active RDM; 3. Data Publication and Preservation. Two ETH units, namely the Scientific IT Services and the ETH Library, provide support for different aspects of these phases, building on their respective competencies. They jointly offer trainings, consulting, information, and materials for the first phase. The second phase deals with data which is in current use in active research projects. Scientific IT Services provide their own platform, <em>openBIS</em>, for keeping track of raw, processed and analysed data, in addition to organising samples, materials, and scientific procedures. ETH Library operates solutions for the third phase within the infrastructure of ETH Zurich’s central IT Services. <em>The Research Collection</em> is the institutional repository for research output including Research Data, Open Access publications, and ETH Zurich’s bibliography.
