The INF project will provide an open-source data management and information infrastructure for the whole CRC 990. The curation and preservation of research data will be integrated into the research data workflows and will use the university data infrastructure currently under construction. Building on this, an option for the citable publication of high-quality research data and its longer-term preservation will be offered. Support and consulting especially for research data management and a scientific communication infrastructure (wikis, publication platform etc.) will be provided.
