Knowledge Graphs for Data Interoperability with Chimera (KG4DI)

This half-day tutorial introduces participants to the practical challenges of achieving data interoperability across heterogeneous sources and to the advantages of an approach based on knowledge graphs [link]. Considering a practical scenario in the mobility domain (the integration of public transport data with open knowledge from Wikidata), participants will learn how knowledge graphs can support data harmonisation and fusion.

The session combines a conceptual introduction with a guided hands-on exercise using Chimera [link], an open-source framework for building declarative and composable semantic data transformation pipelines. Participants will design and execute a complete data integration pipeline — from ingestion of structured data to RDF lifting, SPARQL-based enrichment and construction, and RDF lowering — using only YAML route definitions and declarative mapping templates [link]. No programming experience is required.

v1.0: First version of the tutorial held at the 23rd European Semantic Web Conference (ESWC) on May 11th 2026, in Dubrovnik (Croatia)
