An open ontology framework for interoperability.

Share a machine-readable "map" of what your data means and how it relates to standards, so others can integrate without guesswork.

Discoverable Machine-readable Unifies existing standards

A simple example

Start with a single "well-known" JSON file that tells tools where to fetch your published materials (models, vocabularies, mappings, docs).

{
  "resourceType": "Ontology",
  "id": "example-org",
  "url": "https://ours.example.org/ontology.json",
  "version": "1.0.0",
  "publisher": "ExampleOrg",
  "models": "https://ours.example.org/models.json",
  "vocabularies": "https://ours.example.org/vocabularies.json",
  "mappings": "https://ours.example.org/mappings.json"
}

The point isn't to replace standards. It's to publish how you use them together, in a format tools can fetch and understand.

In development

Detailed specification and comprehensive examples are being prepared. This page will be updated as the work progresses. Learn more

We're looking to build the glue that connects standards together.
