His duties and responsibilities in the team Data & Services Engineering include designing, developing, testing, documenting and implementing software for the data archive.  The software Dataset Documentation Manager (DSDM) facilitates the documentation of cross-national comparative datasets on variable level according to the international standard of the Data Docuemntation Initiative (DDI). DSDM offers interfaces to import SPSS or XML information and to export XML for publication on different dissemination systems and long-term preservation. The project STARDAT aims at the the further development of existing archival tools for curation of study documentations. Currently productive software applications like Data Catalogue, Dataset Documentation Manager or CodebookExplorer will be replaced and the stock of metadata of the archive will be converted to the DDI Lifecycle format. In collaboration with several projects he also works on an integrated search platform for research metadata on study, variable and question level.
