Data catalog

A searchable index of the datasets we hold: what is in them, who owns them, how fresh they are and whether they contain personal data.

Lifecycle

Detail

What this is

An index over the warehouse, event streams and shared object storage, with ownership, freshness and sensitivity classification attached to each dataset.

Who this affects

Anyone who has asked "is there already a table for this?" and could not find out. Nothing is required of dataset owners yet; when rollout begins in December we will ask for classification on datasets we cannot infer.

Updates

Info

First 40 datasets are indexed

Warehouse tables first; event streams and object storage follow. Personal data classification is being reviewed with Legal before anything is opened up more widely.
