What's Cooking in the NFDI4Culture Kitchen? A KG-based Research Data Integration Workflow

The National Research Data Infrastructure (NFDI) aims to provide a standardized and sustainable research data infrastructure across diverse do- mains, facilitating efficient research and scientific advancement. Despite encom- passing a wide range of scientific disciplines, NFDI consortia share a founda- tion of common goals and concepts, emphasizing collaboration and data inter- operability. Leveraging interconnected data offers new research opportunities, but requires availability in Linked Open Data (LOD) format. On example of NFDI4Culture, this paper addresses challenges of heterogeneous and isolated cultural heritage research data, and discusses efforts and results towards the cre- ation of NFDI4Culture-KG, including the establishment of a research data index, implementing an ETL (Extract-Transform-Load) environment, and engineering lightweight semantic representations.
