With the support of 31 institutions, the Swiss Research Data Support Network (SRDSN) project aims to establish a robust and inclusive research data support community in Switzerland. It will facilitate collaboration, knowledge sharing, and best practice development among research data professionals from various disciplines and institutions, including libraries, IT services, core facilities, and research management offices. SRDSN builds on and expands an existing research data support network and the SwissDS-ENV project. It will serve as an organizational framework, facilitating the formation of specialized nodes that address specific areas of research data management starting with a node for Data Stewardship coordinators that will be established during the project.
