Building smart Internet of Things (IoT) applications requires interchanging and using information from others—whether people or machines—and understanding the information unambiguously. To address this issue, the European Telecommunications Standards Institute’s (ETSI) technical committee on Smart Machine-to-Machine Communications (SmartM2M) is leading the Smart Applications REFerence (SAREF) to bring a common understanding across cross-domain heterogeneous systems.
One of the main threats in adopting IoT technologies on a large scale is IoT fragmentation. The current fragmented IoT technology landscape requires standardized interfaces and data models to ensure interoperability. One of the main challenges to ensuring interoperability is to have a set of standard data models for interchanging information and their meaning to avoid misinterpretations between senders and receivers.
The SAREF ontology developed in the SmartM2M Technical Committee at ETSI is a data model enriched with formal semantics. It is intended to enable interoperability between solutions from different providers and among various IoT activity ssectors, thus contributing to the global digital market.
