Defining a New Digital Twin Ontology for Cultural Heritage Preservation – the Case of ARGUS

The sustainable preservation of cultural heritage (CH) assets increasingly demands predictive monitoring approaches that integrate multimodal data and decision support mechanisms. EU project ARGUS introduces a semantic ontology designed to unify sensor observations, diagnostic activities, risk predictions, and conservation decisions within a coherent, operational framework. Building upon standards such as CIDOC CRM, SOSA/SSN, PROV-O, GeoSPARQL, and OWL-Time, the ontology advances heritage computing toward dynamic condition monitoring and preventive conservation strategies.
