ASAM Open X Ontology Overview
What is ASAM Open X Ontology?
ASAM Open X Ontology is an ongoing project started in April 2020 to create a domain model of road traffic using ontology. It defines the concept of load traffic. The created domain model serves as a common basis for the ASAM OpenX standard (Open Scenario, Open Drive, Open CRG, OSI, OpenLabel, OpenODD).
The domain model will be divided into 5 or 6 layers and will cover the layers defined in the Pegasus project. Ontologies are divided into three categories: Core, Domain, and Application.
- Temporary infrastructure such as construction work
- Traffic participants
- Transportation objects such as signs
- Description of environment such as weather and time
- Objects of interest
- Scenario label
Relationship with standardization by other organizations
ASAM Open X Ontology is considering using the following standards:
- W3C Semantic Web: Utilization of Web Ontology Language (OWL).
- ISO704: For domain modeling, take the same approach method as ISO704.
- ISO15926: Considering the use of ISO15926 as a higher-level ontology.
- Scenario description
- Foundation for defining common ASAM OpenX concepts
- Language base of stakeholders Natural language interface
- Semantic error checking
- Semantic search and matching
- Creating an application-specific ontology by extending the core ontology
- Common core ontology for data analysis
- Classification using logical reasoning
