- Growing data volumes and missing local infrastructures to access and re-use scientific data have made data management a common and urgent issue – this particularly seems to be the case at educational organizations including libraries and universities, which started to deal with this complex topic by establishing adequate support services. Funded by the German Research Foundation (DFG), the project RADAR - Research Data Repository - develops a service oriented infrastructure for the preservation, publication and traceability of (independent) research data. Managed by cooperating research institutes from the fields of natural and information sciences, a key feature of the RADAR data archive is a business model offering an interdisciplinary two-stage service:A) A starter package for data preservation up to 15 years andB) A superior package for data publication with DOI assignment and an unlimited storage period.The business model will also include a cost estimation tool for scientists to apply for data management funds. RADAR clients who wish to enhance the prospects of their metadata being found, cited and linked to original research are offered a discipline-agnostic metadata scheme. The scheme allows an accurate and consistent identification of a resource and provides the opportunity to add discipline-specific information for specialized datasets. Our target groups are researchers, libraries, publishers and open platforms that lack access to an appropriate infrastructure to archive and publish their data themselves. As an interdisciplinary repository, RADAR will provide an extension of renowned, discipline-specific data archives and will enable cross-platform data sharing via appropriate interfaces.
