EU Open Data Portal
Type of site
|Public service portal and
|Available in||23 official languages of the EU and soon Croatian|
|Created by||EU Publications Office|
The EU Open Data Portal is the single point of access to a wide range of data held by EU institutions, agencies and other bodies. The portal is a key element of EU open data strategy.
Legal basis and launch date
Launched in December 2012 in beta mode, the portal was formally established by Commission Decision of 12 December 2011 (2011/833/EU) on the reuse of Commission documents to promote accessibility and reuse.
While the operational management of the portal is the task of the Publications Office of the European Union, implementation of EU open data policy is the responsibility of the Directorate General for Communications Networks, Content and Technology of the European Commission.
The portal allows anyone to easily search, explore, link, download and reuse the data for commercial or non-commercial purposes, through a catalogue of common metadata. Through this catalogue, users access data stored on the websites of the EU institutions, agencies and other bodies.
Semantic technologies offer new functionalities. The metadata catalogue can be searched via an interactive search engine (Data tab) and through SPARQL queries (Linked data tab).
There is also a showcase of visualisation applications from various EU institutions, agencies and other bodies.
Users can suggest data they would like the portal to be linked to, give feedback on the quality of data obtainable and share information with other users about how they have used it.
The interface is in 23 EU official languages, while most metadata are currently available in a limited number of languages (English, French and German). Some of the metadata (e.g. names of the data providers, geographical coverage) are in 23 languages following the translation of controlled vocabulary lists that are used by the portal.
Terms of reuse
Most data accessible via the EU Open Data Portal are covered by the Europa Legal Notice  and can be reused free of charge, for commercial and non-commercial purposes, provided that the source is acknowledged. Specific conditions on reuse, related mostly to the protection of third-party intellectual property rights, apply for a very limited amount of data.
The portal contains a very wide variety of high-value open data across EU policy domains, as also more recently identified by the G8 Open Data Charter. These include the economy, employment, science, environment and education. The number of data providers — which include Eurostat, the European Environment Agency and the Joint Research Centre — continues to grow.
So far, around 40 EU institutions, bodies or departments (e.g. Eurostat, the European Environment Agency, the Joint Research Centre and other European Commission Directorates General and EU Agencies) have made datasets available, making a total of over 6,500.
In addition to giving access to datasets, the portal also is an easy entry point to a whole range of visualisation applications using EU data. The applications are displayed as much for their information value as for giving examples of what applications can be made using the data.
Architecture of the portal
The portal is built using open source solutions such as the Drupal content management system and CKAN, the data catalogue software developed by the Open Knowledge Foundation. It uses Virtuoso as an RDF database and has a SPARQL endpoint.
