open-ontologies

Build, validate, and govern RDF/OWL knowledge graphs

Builds, validates, queries, and versions RDF/OWL ontologies and knowledge graphs through 70+ connected operations. Eliminates manual triple-store setup, broken Turtle syntax, and untracked schema changes with automated linting, SHACL checks, and reasoning. Adds Terraform-style plan, apply, drift, and rollback controls so ontology changes ship safely into production.

Frequently Asked Questions

FAQPage Schema
How to install Open Ontologies?▼

Run `npx skills add fabio-rovai/open-ontologies --all -g -y` in your terminal to install all skills in this suite globally.

How to build an ontology with AI?▼

Describe your domain in plain English and the agent generates OWL/Turtle directly, then validates, lints, and queries it until every check passes.

Can it turn CSV or SQL data into a knowledge graph?▼

Yes. It ingests CSV, JSON, XLSX, Parquet, and SQL query results from PostgreSQL or DuckDB into RDF, then validates with SHACL and runs inference.

Does Open Ontologies work with Claude Code and Cursor?▼

Yes. It runs as a standard MCP server, so the onto_* tools work in Claude Code, Claude Desktop, Cursor, and any MCP-compatible client.

Do I need a database or JVM to run it?▼

No. It ships as a single Rust binary with an in-memory Oxigraph triple store, so there is no database, JVM, or external service to configure.
