Madrid City Council joins the promotion of open data with a new data competition

Madrid City Council has launched an initiative to demonstrate the potential of open data: the first edition of the Open Data Reuse Awards 2025. With a total budget of 15,000 euros, this competition seeks to promote the reuse of the data shared by the council on its open data portal, demonstrating that they can be a driver of social innovation and citizen participation.

The challenge is clear: to turn data into useful, original and impactful ideas. If you think you can do it, below, we summarize the information you must consider to compete.

Who can participate?

The competition is open to practically everyone: from individuals to companies or groups of any kind. The only condition is to submit a project carried out between September 10, 2022 and September 9, 2025 and that uses at least one dataset  from the Madrid City Council's open data portal as a base. Data from other public and private sources can also be used, as long as the  Madrid City Council datasets are a key part of the project.

Of course, projects that have already been awarded, contracted or financed by the City Council itself are not accepted, nor are works submitted after the deadline or without the required documentation.

What projects can be submitted?

There are four main areas in which you can participate:

• Web services and applications: refers to projects that provide services, studios, web applications, or mobile apps.
• Studies, research and ideas: refers to projects of exploration, analysis or description of ideas aimed at the creation of services, studies, visualizations, web applications or mobile apps. Bachelor's and master's degree final university projects can also participate in this category.
• Proposals to improve the quality of the open data portal: includes projects, services, applications or initiatives that contribute to boosting the quality of the datasets published on the Madrid City Council's open data portal.
• Data visualizations: you can participate in this category with various content, such as maps, graphs, tables, 3D models, digital art, web applications and animations. Representations can be static, such as infographics, posters, or figures in publications, or dynamic, including videos, interactive dashboards, and stories.

What are the prizes?

For each category, two prizes for different economic endowments are awarded:

Beyond the economic prize, this call is a great opportunity to give visibility to ideas that take advantage of the transparency and potential of open data. In addition, if the proposal improves public services, solves a real problem or helps to better understand the city, it will have great value that goes far beyond recognition.

How are projects valued?

A jury will evaluate each project by assigning a maximum score of 50 points, which will take into account aspects such as originality, social benefit, technical quality, accessibility, ease of use, or even design, in the case of visualizations. If deemed necessary, the jury may request further information submitted to the participants.

The two projects with the highest score will win, although to be considered, the proposals must reach at least 25 points out of a possible 50. If none of them meets this requirement, the category will be declared void.

The jury will be made up of representatives from different areas of the City Council, with experience in innovation, transparency, technology and data. A representative of ASEDIE (Multisectoral Association of Information), the association that promotes the reuse and distribution of information in Spain, will also participate.
