An infrastructure approach serving DDI3.x

nbsp;Embedded in a trans-disciplinary strategy for the institutional research data management, the Data Service Center for Business and Organizational Data (DSZ-BO) is currently established at the Bielefeld University. The goal is to bridge the gap between data producers and data consumers by providing an infrastructural framework for the acquisition, standardization, preservation, dissemination and - if appropriate discovery and reuse - of scientific data. Beside the identification of the requirements and workflows within the sociological research, there is a technical challenge for developing a DDI3.x-based infrastructure which covers as many of the peculiarities in the description and management of quantitative/qualitative data and its metadata from (longitudinal) surveys. Furthermore, the description of organizational data is very complex and needs another focus of documentation, e.g. usage of controlled vocabularies for the classification of employers. In this presentation we will explain our multi-layer architecture for efficient storage, retrieval, presentation and enabling secondary analysis on the basis of DDI which are relative to DSZ-BO research problems. Furthermore generic add-on services will be considered which connect the data archive with a repository. This enables persistent identification and bidirectional linking of research data and publications as well as access rights management, versioning and data export functionalities.
