Scope & objectives
Originally, the European Cluster on the Internet of Things (IERC AC4) [IERC AC4 2025] defines four dimensions of Interoperability (technical, syntactical, semantic, and organizational).
Later, the European Interoperability Framework (EIF) [EIF] has defined four interoperability layers (legal, technical, semantic, and organisational).
We mainly on focus on the semantic interoperability layer applied to different domains in EU projects such as energy (IntNet, OMEGA-X, Interconnect), health (ACCRA), security and privacy (PDP4E) and via standards (via HSBOOSTER, StandICT).
Recommendations for future work on semantic interoperability are encouraged [Future].

The Ontology-Driven Constraint Tester (ODCT) is a robust framework created to validate datasets against ontologies defined by SAREF and SAREF4ENER, both established under ETSI SmartM2M. This tool has been applied to the Flexible Start use case from the Joint Research Centre’s (JRC) Code of Conduct for Energy Smart Appliances. The ODCT tool ensures that smart devices like energy-efficient washing machines, thermostats, and connected lighting operate in compliance with established ontologies, thereby enhancing their interoperability within energy management systems and smart grids.
