Open Research Data (ORD) and effective Research Data Management (RDM) are crucial components of Open Science, promoting scientific transparency, accessibility, and reproducibility. However, researchers often encounter barriers to adopting ORD and RDM practices, including unclear benefits, fear of data misuse, or lack of accessible training. The Data Management Campus, an initiative of the ETH Domain (Swiss Federal Institutes of Technology), addresses these challenges through learning modules tailored to researchers' needs and an Open Educational Resources (OER) approach that caters to trainers.

Grounded in comprehensive surveys, stakeholder consultations, and expert input, the modules are to be delivered as centralized, accurate, and practical online learning sequences (modules) on the Swiss MOOC Service, complemented by the underlying OER material via an associated Zenodo community. This paper outlines the Campus's development process, including needs assessment, content creation, platforms selection, and challenges in researcher engagement and long-term sustainability.
