JCAT Labs is the infrastructure layer for enterprise knowledge. Model, align, govern and serve taxonomies, ontologies and knowledge graphs across billions of entities, then plug them into every system that needs to reason over your data.
No credit card. Open-source core. Curated & hosted when you're ready to scale.
Most teams can stand up a triple store in an afternoon. Keeping a taxonomy, ontology and knowledge graph correct, aligned and governed as it grows to enterprise scale is the hard part. That's the part we built.
Author taxonomies and ontologies, or import what you have — RDF, OWL, SKOS, spreadsheets, legacy schemas. Mappings are generated, not hand-typed, and validated against your shapes.
Merge overlapping vocabularies across teams, vendors and acquisitions. Candidate matches are scored, adjudicated and explained, so reconciliation is auditable rather than a black box.
Every change is diffed, reviewed and versioned with full lineage. Roll back, branch, and prove exactly what your ontology looked like on any date, for any audit or regulator.
One API and SPARQL endpoint for your whole organisation. Sub-100ms queries over billion-triple graphs, feeding search, RAG, analytics and agents from a single source of truth.
The JCAT engine is built on an open-source, lightweight Python core. The thing that models, validates and serves your ontology is yours to run, free, with no seat limits and no expiry. We never paywall the engine.
Point JCAT at your schemas, catalogues, spreadsheets and existing ontologies. It maps and normalises them into standards-native RDF.
Overlaps are detected, scored and resolved. Our curation layer hardens the result into a canonical, governed taxonomy your whole org can rely on.
Expose one endpoint to search, analytics, RAG pipelines and AI agents. Versioned, monitored, and scaled by our managed infrastructure.
The engine is always free. You pay only for curation and managed infrastructure when you outgrow doing it yourself.
