c0mm0.com — the continuously verified register of European data

Open Knowledge Format

The register, as an OKF 0.1 bundle

Every API, dataset, publishing institution and license in the register is published as a conformant Open Knowledge Format bundle — plain Markdown with YAML frontmatter, cross-linked into a knowledge graph an agent can clone and traverse. Unlike one-shot OKF dumps, ours is continuously re-verified: each concept carries live verification status and per-field provenance, and the bundle is rebuilt whenever a source changes.

Consume it

Clone the whole bundle

One tarball, one directory of Markdown concepts — drop it into a repo, a RAG index, or an agent's working set.

curl -L https://c0mm0.com/api/v1/okf/bundle.tar.gz | tar xz

Read one concept live

Each concept renders from the database on request, so a single fetch is always current.

What's inside

Conformant with OKF v0.1. Bundle metadata is CC0-1.0; the underlying APIs and datasets keep their own licenses. See also the verification methodology and the DCAT-AP catalog.
