A Feasibility Study With Two Datasets on the Application of the Early Stage HDTO Ontology in Practice

This paper documents the practical implementation of the Heritage Digital Twin Ontology (HDTO) as a feasibility of the FinFAIR project, which is buillding on results of OpenMusE and provides an exploitation pathway for it. It demonstrates how cultural heritage data can be modelled as interoperable digital twins. It introduces a rights-aware data model that integrates the Europeana Data Model (EDM) and Open Digital Rights Language (ODRL) through a simplified Wikibase representation. The approach supports transparent licensing, GDPR compliance, and machine-readable policies for multimodal heritage objects such as music, architecture, and fieldwork archives. The paper outlines mappings, examples, and RDF exports designed for reuse across the European Collaborative Cloud for Cultural Heritage (ECCCH).
