open-ontologies
Eliminates JVM overhead and deployment friction for teams needing semantic reasoning at scale.
AI-native ontology engine: a Rust MCP server with tools for building, validating, querying, and reasoning over RDF/OWL ontologies. In-memory Oxigraph triple store, native OWL2-DL tableaux reasoner, SHACL validation, SPARQL, versioning. Single binary, no JVM.
- Generate RDF ontologies from business domain descriptions and validate them automatically.
- Query knowledge graphs with SPARQL to find relationships between data entities across systems.
- Validate data quality against ontology rules using SHACL before loading into production.
Eliminates JVM overhead and deployment friction for teams needing semantic reasoning at scale. Native OWL2-DL reasoning with SHACL validation reduces data quality incidents and enables knowledge graph automation without external services.
Data engineering teams building knowledge graphs or semantic data pipelines requiring fast, validated ontology reasoning.
