What is the European Union Open Data Portal?

The European Union Open Data Portal is the single point of access to a growing range of data from the institutions and other bodies of the European Union (EU). Data are free for you to use and reuse for commercial or non-commercial purposes.

By providing easy and free access to data, the portal aims to promote their innovative use and unleash their economic potential. It also aims to help foster the transparency and the accountability of the institutions and other bodies of the EU.

The EU Open Data Portal is managed by the Publications Office of the European Union. Implementation of the EU's open data policy is the responsibility of the Directorate-General for Communications Networks, Content and Technology of the European Commission.

What can I find on the portal?

The portal provides a metadata catalogue giving access to data from the institutions and other bodies of the EU. To facilitate reuse, these metadata are based on common encoding rules and standardized vocabularies.To learn more, see Linked Data.

Data are available in both human and machine readable formats for immediate reuse. You will also find a selection of applications built around EU data.To learn more, see Applications.

How can I reuse these data?

As a general principle, you can reuse data free of charge, provided that the source is acknowledged (see legal notice).Specific conditions on reuse, related mostly to the protection of third-party intellectual property rights, apply to a small number of data. A link to these conditions is displayed on the relevant data pages.

How can I participate in the portal?

Another important goal of the portal is to engage with the user community around EU open data. You can participate by:

  • suggesting datasets,
  • giving your feedback and suggestions, and
  • sharing your apps or the use you have made with the data from the portal.

How does the search functionality work?

The search field on the data tab allows you to search for datasets using plain text or to look into particular fields of the datasets.

For the plain text option, the input text will be searched for within all the metadata fields. With the radio buttons below the search field it is possible to refine the behaviour of the search engine by selecting “all of these words”, “any of these words” or “the exact phrase”.

To search using a specific metadata field, the input string can be prefixed with the name of the field. For instance, to search for:

  • “forest” only in the title field, the query would be title:forest
  • "forest" only in the description, the query would be notes:forest
  • "forest" only as a keyword, the query would be tags:forest

To search for version number, modification or issue dates, the queries would be as follows:

  • version:4_4
  • modified=2014-02-27
  • issued=2014-02-21

The list of fields can be found on the worksheet specification (column CKAN fields).
