Open data portals

Open data portals facilitate access to and reuse of public sector information. They can help encourage cross-border use of reusable data in Europe.

Open data portals are web-based interfaces designed to make it easier to find reusable information. Like library catalogues, they contain metadata records of datasets published for reuse, mostly relating to information in the form of raw, numerical data rather than textual documents.

In combination with specific search functionalities, they facilitate finding datasets of interest. Application programming interfaces (APIs) are often available as well, offering direct and automated access to data for software applications.

Open data portals are an important element of most open data initiatives and are mainly used by public administrations at European, national and local level in EU countries. Notable examples of Open Data portals maintained by public administrations in Europe are:

While supporting policy development by offering easy access to published data, open data portals can also work as a catalyst triggering the publication of more and better quality data. For administrations obliged or willing to disseminate their data, they offer the advantage of providing public access without the need to reply to individual requests for access to data. And, more and more companies are opening up some of their data for developers to reuse.

The European Commission offers an open data portal for any type of information held by the Commission and other EU institutions and bodies. The European Union's Open Data Portal has been in operation since December 2012.

The European Data Portal

The European Commission has funded the European Data Portal through the Connecting Europe Facility programme. The portal is a pan-European repository of public sector information open for reuse in the EU. It offers a training centre on how to reuse open data and a database of success stories from European and international re-users.

The principal function of the European Data Portal is to provide a single point of access in all 24 EU official languages for data published by public administrations at all levels of government in Europe (EU countries, countries of the European Economic Area and certain other European countries).

In order to foster comparability of data published across borders, it presents metadata references in a common format (Data Catalog Vocabulary application profile for data portals in Europe), using resource description framework (RDF) technology.  It provides translations of metadata descriptions in all 24 languages using machine-translation technology.

The portal complements national, regional and thematic open data portals, and the EU's Open Data Portal. Each of these portals target relevant user audiences, offering tailored content. This infrastructure will stimulate cross-border use of reusable information in Europe by improving the findability of data across countries and supporting the development of data applications and products including data from different countries. For example, by offering assistance on applicable licensing conditions.


New rules on Open data and reuse of public sector information start to apply

Tomorrow, 17 July 2021, will mark the deadline for Member States to transpose the revised Directive on open data and reuse of public sector information into national law. The updated rules will stimulate the development of innovative solutions such as mobility apps, increase transparency by opening the access to publicly funded research data, and support new technologies, including artificial intelligence.

Commission seeks views on data sharing

The European Commission has launched an open public consultation on the announced Data Act aiming to create a fair data economy by ensuring access to and use of data. The consultation seeks to gather views from citizens, businesses, online platforms, academics, civil society, administrations and all interested parties. It is open until 3 September.
