The dataset involves a comprehensive ontology and rule base, developed with industry experts and instantiated from GIS, sensor, and EPANET data for a Welsh pilot. The ontology and rule base underpin a test web service, developed as part of a research project, to provide discoverability, context and meaning for the sensor readings stored in a scalable database. The goal of the service was to aid in decision making and an interface displays sensor data and fault inference notifications, leveraging the complementary nature of serving coherent lower and higher-order knowledge. The underpinning rules are also provided as well as validation data.
