ONS data discovery Open Knowledge Format demonstrator

Metadata-only · evidence-led · read-only

Find the exact dataset.
See what you might confuse it with.

Search across ONS Data API, Nomis, Open Geography and Explore Local Statistics metadata. Reduce the candidate set, compare material differences, inspect quality evidence, then create a non-executing candidate plan that requires live validation and authorisation.

This page loads a bounded, comparison-rich projection for a fast live demo. The linked OKF Explorer index searches all 5,097 frozen records. This is an independently published experimental bundle; source attribution does not imply endorsement by ONS or another producer.

Explainable discovery

The result is a decision, not just a title match

  1. Reduce: deterministic text matching and explicit facets create a reviewable candidate set.
  2. Differentiate: population, measure, unit, geography, time, frequency, version and method are compared.
  3. Verify: QMI, methodology, provenance, revisions and standards evidence stay linked to the source.
  4. Configure: required dimensions remain explicit until a read-only MCP plan is valid.

Inspectable by agents
