The SAREF ontology model is further specialized in various verticals, including, for example,
building, energy and water, and defines the ontologies and relationships for each specific one. As

for smart city data oriented to the IoT”. The diagram below presents an overview of the main classes
of SAREF4CITY and their relationships. (SAREF4CITY, 2020):
