Overview

The SUNRISE Ontology formalizes key concepts and relationships related to ODDs and scenarios within the SUNRISE project. It is aligned with the taxonomies defined in ISO 34503 and ISO 34504, ensuring compatibility with international standards for scenario-based testing and verification.

The ontology models dynamic entities, environmental conditions, and scenery elements along with their respective attributes. It also captures exposure metrics and scenario metadata, providing a structured foundation for representing and exchanging information in simulation and testing contexts.
