Publications and education

The portal publishes many publications ranging from the yearly Open Data Maturity report to specific data stories and open data news.

The portal offers news and social media coverage on open data topics, with the purpose of educating and informing citizens about the opportunities that using and reusing public data resources can bring. It also hosts the data.europa academy, a knowledge hub for open data-related topics, and publishes a quarterly newsletter.

The 'country insights' section of the portal provides insights into the status of open data in European countries. The section includes information about countries' national open data portal, the level of open data maturity, use cases, catalogues, events, reports, news, webinars and interviews about open data.

The 'use cases' section offers a catalogue that includes hundreds of use cases from both publishers and people who reuse open data.

The portal is linked to other activities that demonstrate the potential of open data, such as the EU Datathon (an annual open data competition), the EU Open Data Days (a worldwide conference about open data and data visualisation) and different online seminar series (EU DataViz webinars, EU Open Data Explained webinars and data.europa academy webinars).

The portal also offers documentation on general recommendations for topics like data citation and data quality.

Finally, the portal researches and documents the impact of open data in reports such as the 2020 report on The Economic Impact of Open Data -- Opportunities for value creation in Europe. The study forecasts the open data market size and employment growth for 2025. The impact is exemplified by efficiency gains and cost savings due to open data.

Open data maturity

The study on open data maturity serves as benchmark to gain insights into the development of European countries in the field of open data. This yearly assessment, started in 2015, presents the overview to better understand the countries level of maturity on open data. The study captures their progress over time and areas of improvement and benchmarks them against other countries. The report assesses the maturity against four dimensions:

    1.  policy
    2.  portal
    3.  impact
    4.  quality

It also provides an overview of best practices implemented across Europe and a set of recommendations tailored to the level of maturity and characteristics of each group. Every year, the data is collected through a questionnaire sent to national open data representatives working in collaboration with the European Commission and the Public Sector Information Expert Group.

Data stories

Data stories are a set of monthly articles that inspire and inform you about open data trending initiatives. They highlight examples of good practices and innovative techniques across the world on open data.


The portal commits to open data research and learning as key milestones to keep updating in this constantly changing data ecosystem. This section provides a full collection of the research developed on several topics.

To help you find the right course, it is structured along four themes according to the open data maturity assessment: policy, impact, technology and quality.

It provides complete and up-to-date knowledge about tools and how to publish high-quality open data, whether you are an expert or just getting started.

EU Open Data Days

The EU Open Data Days in 2021, was the first-ever event of its kind and took place from 23 to 25 November 2021. It comprised EU DataViz, an international conference on open data and data visualisation, followed by the finals of EU Datathon, the annual open data competition.

The EU Open Data Days were designed to be relevant to all open data stakeholders and data users, with a special emphasis on the needs of the EU's public sector. The event attracted well over 2 000 registrations from data enthusiasts, data visualisation experts and solution-seekers. On the stage, different sectors of the society were represented, with more than 70 speakers coming from all around the world to bring their expertise for public administrations.

The EU Open Data Days were organised by the OP, with the active support of over 60 partners, representing the data providers from EU institutions and agencies, European national open data portals and national statistical offices, the key digital players in Luxembourg.

You can access the recordings and presentations online.

EU Datathon

EU Datathon is an annual open data competition organised by the OP since 2017. The competitions are organised to create new value for citizens through innovation and promote the use of open data available on the portal.

EU Datathons gather teams of people from all over Europe to stimulate innovation, creating a bridge between citizens and the EU's administration. As a result, new applications are developed to improve existing services or create completely new ones. The competitions have also demonstrated that potential users do need these initiatives for visibility purposes before potential business partners.

Open data demonstrated in every edition how powerful it could be, in every sector of society. It showed us how it could help in the creation of start-ups, innovative products and services; it promotes transparency in the public sector, addresses current societal challenges, boosts economic growth and accelerates scientific progress.

Every EU Datathon competition showed innovation when teams tackled different challenges, such as helping to achieve the digital single market (e.g. Tenderlake and, making legislation more interoperable (e.g. The Smartfiles Network and Lexparency), offering innovative technology relating to medicines (e.g. Medicatio and Open Food Facts) or tackling climate change (ODCCI) through a platform which optimises irrigation to reduce water waste (e.g. Chloe irrigation system).

These examples, among others, uncover how accessible and reusable data can help to build a better future.

EU Datathons are organised in collaboration with partners in EU institutions and Member States to address domains of primary importance for citizens, the public sector and businesses: legislation, medications, food safety and public procurement, among others.

This interinstitutional collaboration highlights the common goals to be closer to citizens and support innovative start-ups. Additionally, by facilitating cooperation between public entities and the private sector, EU Datathons generate innovative ideas for open government, offering a platform for all sides to exchange information and learn.

Moreover, it is a new, more direct way of interaction between citizens, innovative youth and the EU administration and it can generate a positive atmosphere around the Commission and the EU institutions in general.
