Aligning defence upper ontologies for national digital twin consistency
Three upper ontologies used in UK and NATO defence data infrastructure—IES, HQDM (underpinning the National Digital Twin), and BFO—were aligned. A hand-curated crosswalk of 17 correspondences was promoted to OWL and reasoning over merged ontologies was performed. Results are important for data interoperability.
Why it matters
Ontology alignment is critical for data integration in large government digital ecosystems like the national digital twin.
