EU Open Data Portal

The official open data portal of the European Union, run by the Publications Office. It harvests the metadata of the national open data portals of all EU member states (and several EEA and candidate countries), many regional and city portals, geodata catalogues and the EU institutions and agencies, so one search covers them all. The files themselves stay on the publishers' servers.

Yes. Keywords work in any EU language. The portal machine-translates most titles and descriptions, so you can ask for results in your language; the connector falls back to English and then to the original language, and tells you when a title is in another language or machine-translated.

The connector downloads the start of the file from the publisher's server, reads only what it needs and returns the first rows and columns (up to 100 rows and 50 columns). CSV and TSV are streamed, so even very large files work: reading stops after the requested rows or 2 MB. JSON and GeoJSON must be read whole and are limited to 5 MB. Excel, ZIP, PDF, XML, shapefiles and map services cannot be previewed; you get the download link instead. Nothing is stored.

The portal's search index only pages through the first 10,000 results of a query. Add filters (country, portal, format, theme or dates) to narrow it down; use the counts tool to see where the data is.

The data comes straight from the public data.europa.eu API. The connector is an independent client with no affiliation to the European Union or the Publications Office. Each dataset keeps the licence set by its publisher, shown with every file.

Themes (EU data themes such as transport or environment) are set by the source portal. Some portals, Portugal's for example, do not tag them; filter by keywords, publisher or format instead.
