29 - 30 April Justus Lipsius Building, Brussels

Want to build an application that enables European citizens to truly understand what is going on in Europe?

Are you interested in European data and want to create new transparency applications on top of this data? Want to make decision-making on a European level searchable and understandable for everyone?

Then join us at Diplohack Brussels. We're inviting everyone to join us, whether you’re a diplomat, developer, designer, citizen, student, journalist or activist. We will connect different profiles together in teams to use European data for good.The idea is that you create a prototype or MVP with this data in just 24 hours. We will support you in any way possible, explain the data and help you get started.

Friday - Saturday 29 - 30 April

Council of the European Union,
Justus Lipsius Building
Rue de la Loi / Wetstraat 175,

Who can participate?

We will create multi-skilled teams based on the different profiles who are present. We're inviting diplomats, journalists, developers, designers, students, citizens, civil society actors, social entrepreneurs, academics and basically anyone who want to use and re-use public open data to hack diplomatic issues. If you feel this topic appeals to you then you are more than welcome.

The Diplohack

A Diplohack is a hackathon focused on creating synergies between the skill sets of people from a wide variety of backgrounds, such as diplomats, developers, designers, NGOs etc. In this case we will use these collaborative and creative methods to build applications that give citizens more insight and usable information about European decision-making.

The Datad(r)ive

On the 15th of April we hosted a webinar together with the EU institutions to talk about the available data and the technical details.

There is a video and a summary with all necessary links on our blog.

The Data?

The Council of the European Union and the EU institutions already have an extensive catalogue of open datasets, which you can use to build your application. These cover many different aspects, including Politics, Law, Transparency and Finance. On the EU Open Data Portal you can see which datasets are already available.

On the EU Open Data Portal you can see the datasets published by the European Union institutions. Similarly, the European Data Portal provides data from all member states as well.
