Digital curation and preservation of large and complex scientific objects: Data Life-Cycle Management - The Swiss Way. We target in the context of a national program (CUS-P2) the setting up of the the required services that will allow the efficient management of active research data, and ensure the publication, long-term reference and preservation of subsets of data selected by researchers. Through this project we intend to implement concrete high-impact use cases of exemplary research data life-cycle management solutions, along with guidelines and training, so that researchers and their supporting scientific IT and library teams can apply the results themselves in their daily data management activities.
