Application-Level
The application layer of the Naas Ontology provides implementation-specific concepts that handle the practical aspects of deploying and managing ontological systems in production environments.
Application Architecture​
Application-level ontologies bridge domain concepts with specific implementation requirements:
Foundry Ontology​
The FoundryOntology.ttl provides the infrastructure for organizing and curating ontological concepts across different foundries (organizational contexts).
Foundry Curation System​
@prefix abi: <http://ontology.naas.ai/abi/> .
@prefix bfo: <http://purl.obolibrary.org/obo/> .
@prefix cco: <https://www.commoncoreontologies.org/> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
# Core foundry curation property
abi:is_curated_in_foundry a owl:DatatypeProperty ;
rdfs:label "is curated in foundry"@en ;
skos:definition "Relates a class to the foundry it is curated in."@en ;

Foundry Categories​
The system defines several foundry categories for different organizational contexts:
# Enterprise management foundry

Implementation in ABI​
The application layer concepts are operationalized through ABI's infrastructure:
Foundry Management​
- Curation workflows - Systematic assignment of concepts to foundries
- Access control - Role-based permissions for foundry access
- Organization mapping - Alignment of foundries with organizational structure
Data Source Integration​
- Automatic discovery - Detection and cataloging of data sources
- Quality monitoring - Continuous assessment of data quality metrics
- Schema evolution - Management of data schema changes over time
Next Steps​
The application layer provides the foundation for:
- Process-Centric Routing - AI routing based on application context
- Production deployment - Real-world implementation of ontological systems
- Organizational integration - Alignment with business processes and governance
The application layer bridges ontological concepts with practical implementation requirements, enabling the deployment of semantic systems in production environments.
