data.europa.eu MQA — Metadata Quality Assurance

DCAT-AP quality scores (0–450) for EU datasets, catalogues and countries. Filter out low-quality sources.

MQA is data.europa.eu's official DCAT-AP quality engine. Each dataset is scored on five dimensions (Findability 100, Accessibility 100, Interoperability 110, Reusability 75, Contextuality 20 — 450 points in total) based on SHACL validation against DCAT-AP. Used as a moat: the living record can prioritise datasets with high metadata quality, and municipalities/auditors can filter out sources below a threshold. Cached for 7 days (recomputed weekly upstream). Issue #3256.
