University of Basilicata LISUTFaculty of Engineering Laboratorio di Ingegneria dei Sistemi Urbani e TerritorialiDepartment of Architecture, Planning and Transport Laboratory of Urban and Regional Systems EngineeringInfrastructure Lack  of  data  vs  interoperability   Three main barriers: •  Bureaucratic: poor practice in sharing data •  Technological: differences between systems and data formats •  Semantic: lack of correspondance in meanings.
