An instance of the KIT Data Manager Base Repo (Jejkal et al., 2014) is used as a research data repository for all CRC subprojects. Existing data from the subprojects is stored as structured data objects including their respective metadata in the form of TEI compliant XML files (Burnard and Bauman, 2010) and is available for further processing, enrichment, analysis, etc. via standardized interfaces. In close collaboration with the subprojects, the INF project is evaluating existing representations of their data, required format conversion, legal aspects and rights management, as well as assisting the provision of required descriptive metadata.
