Introduction back to ToC
CELINE (Cross-sectorial integrated digital services Enabling energy Localized INnovation and community Empowerment) is a Horizon Europe research project (Grant Agreement No. 101160667) that develops a Digital Toolbox for households, energy communities and cooperative organisations to optimise energy management and support investment decisions around photovoltaic systems, battery storage, electric vehicles and heat pumps. The project validates its solutions across three European demonstration sites in Spain, Finland and Italy.
The CELINE Core Ontology supports the semantic layer of this toolbox. It is a thin orchestration profile -- not a standalone domain ontology -- that binds together existing standards into a coherent semantic target for the CELINE ecosystem:
- **PECO** (https://purl.org/peco) models the Energy Community structure, members, PODs and assets.
- **SAREF / SAREF4ENER** (ETSI) covers smart devices and energy assets.
- **SOSA/SSN** (W3C) covers sensor observations and measurements.
- **IEC CIM** (IEC 61968) provides the reference model for grid topology, aligned via skos:closeMatch.
Version 0.7 extends the ontology with:
- **hasDataset**: A new object property linking assets and connection points to external, self-describing datasources (DatasetReference). This is the operational counterpart to the SimulationRun-scoped usesDataset/producesDataset properties.
- **DatasetReference self-description**: Clarified that instances SHOULD declare conformance target (dct:conformsTo), format (dct:format), and access location (dcat:accessURL or dct:source) using DCAT/Dublin Core terms. DCAT prefix added (no owl:imports).
- **Implementation-neutral wording**: All references to specific external catalogue products have been replaced with generic wording ("an external catalogue") throughout the ontology.
