A home for clear business meaning
Give your company and your AI agents one shared meaning for every key word.
Ontologies Hub is where people and machines agree on what things mean, then reuse that meaning everywhere.
The core promise
When "Customer" means one thing in Salesforce and another in QuickBooks, reports lie, APIs fight, and AI guesses.
LLMs can guess.
Your business cannot.
Ontologies Hub turns your messy, conflicting definitions into a clear, shared language:
- One meaning for each concept
- Written as facts, roles, and constraints
- Easy for humans to read
- Precise enough for machines to trust
So every system, every team, and every agent plays by the same rules.
What Ontologies Hub is
A web app to:
- Model your business as concepts, roles, facts, and constraints
- Visualize ontologies in views people can actually read
- Collaborate, review, and version like code
- Publish public ontologies or keep them private on team spaces
An MCP server to:
- Let tools and agents query definitions at runtime
- Answer questions like
- "What does Customer mean here"
- "Show constraints for Order"
- "Give me a schema for fulfillment only"
- Enforce model constraints before code runs or data moves
A marketplace to:
- Browse public ontologies
- Fork, remix, and align them to your own
- Ship alignment packs to partners and standards
All from one place: Ontologies Hub.
