This project transforms publicly available transport data into a knowledge graph and visualizes it through an interactive application, using RDF. For simplicity, the project focuses on German long-distance trains using both GTFS static data and Deutsche Bahn’s official API. The implementation highlights the potential of semantic technologies for transport information systems, achieving query times under 100ms and processing approximately 30,000 RDF triples across 439 stations.
