The Knowledge Graph Infrastructure (KGI4NFDI) is a basic service under development for the German National Research Data Infrastructure – NFDI. KGI4NFDI aims to serve researchers, consortia, and institutions by becoming your gateway to seamless, connected, and FAIR (Findable, Accessible, Interoperable, and Reusable) research data. KGI4NFDI enables the creation, exploration, and harmonization of knowledge graphs (KGs) across diverse disciplines and international frameworks. KGI4NFDI is currently in its initialisation phase, the first of three service development phases.
