These standards enable interoperability and therefore contribute to the development of the global digital market.
When the European Commission launched the SMART 2013/0077 Standardization Initiative on smart appliances, a survey was conducted. The outcome was to create commonly agreed semantics for smart appliances and build a reference ontology as an interoperability language, and, with the help of TC smartM2M and oneM2M, these standards are now a reality.
“The first ETSI SAREF specification was released in 2017; it was the first standard ontology in the Internet of Things (IoT) ecosystem. As the IoT addresses a diversity of activity sectors and even the same specific function or feature, it may not be understood and interpreted the same way,” says Enrico Scaronne, Chair of ETSI TC smartM2M. “The smartM2M specifications provide interoperability between solutions from different providers and among various activity sectors. These standards are designed to run on top of the oneM2M system, the IoT partnership project of which ETSI is a founding partner. OneM2M provides the communication and interworking framework to share the data among applications; SAREF provides the semantic interoperability necessary to share the information carried by the data.”
The SAREF4CITY specification, ETSI TS 103 410-4, has been developed with the stakeholders who would need ontology such as other standardization bodies, associations, IoT platforms and European projects and initiatives. Use cases include eHealth and smart parking, air quality monitoring, mobility and street lighting. SAREF4CITY provides a common core of general concepts for smart city data for the IoT.
