SowiDataNet|datorium is a research data repository for social sciences and economics that enables researchers to easily and securely document, publish and share (quantitative) primary and secondary data. The repository is geared to the needs of the scientific community: a comprehensive metadata schema provides an opportunity to describe the research data in detail, which is the prerequisite for effective reuse. With the publication in SowiDataNet|datorium, research data become citable because they are given a persistent identifier, namely a "Digital Object Identifier (DOI)". A two-stage review process also guarantees a quality and technical quality check of the data.
