SUMMARY:CIM Users Group Meeting 2026
DESCRIPTION:Semantic Interoperability Tests based on IEC CIM in European Energy Data Space and associated to EU Regulation \nAt the CIM Users Group Meeting 2026\, EDF R&D and Trialog\, partners in the O-CEI Horizon project\, will participate and present their joint contribution entitled “Semantic Interoperability Tests based on IEC CIM in European Energy Data Space and associated to EU Regulation\,” in collaboration with ENEDIS\, the main French DSO. \nIn the context of the Energy Data Space Program promoted by the EU Commission and associated with implementing the act on Metering and Customer Data Access (https://eur-lex.europa.eu/eli/reg_impl/2023/1162/oj/eng )\, semantic interoperability ensures that data providers and service providers of distinct data spaces have a common understanding of shared datasets. \nThis presentation will describe the semantic interoperability tests performed amongst five Energy Data Space projects (DATA CELLAR\, EDDIE\, ENERSHARE\, OMEGA-X\, and SYNERGIES) in March 2025. These tests were based either on EUMED Metering (which is an international standard based on IEC CIM (Common Information Model) of the International Electrotechnical Commission or on EME (EUMED METERING Ontology)\, which is an ontology developed in OMEGA-X as part of its Common Semantic Data Model (CSDM) and the result of the semantization of EUMED Metering. \nBuilding on these successful tests\, our objective is to translate exchange specifications into machine-checkable constraints that produce clear pass/fail results and auditable evidence. The main challenge is to keep the validation lightweight and technology-neutral\, while ensuring datasets remain aligned with shared semantic artefacts\, in particular EUMED Metering and its EME semantization. Within the O-CEI project\, this will be delivered as a Validation and Verification (V&V) platform through a joint open-source initiative centred on the Ontology-Driven Constraint (ODC) Tester\, integrating the EME Validation Service into a reusable validation core. \nThe elaboration of the CSDM in OMEGA-X in which Trialog and EDF were involved\, was also closely related to IEC system committee Smart Energy work on ontologies which published IEC SRD 63417:2025 “Guidance and plan to develop smart energy ontologies”.  All this work will feed the EU Smart Energy Expert Group which recommends developing a coordinated European Testing Action Plan for energy interoperability\, bridging with the transport sector and other sectors where relevant\, and linking national authorities\, standardisation bodies\, testing laboratories\, and expert communities.
