Descripción
Just a few months after the success of its first award, the Madrid City Council has opened the call for the second edition of the Open Data Reuse Awards. It is an initiative that seeks to recognize and promote innovative projects that use the datasets published on the datos.madrid.es portal. With a total endowment of 15,000 euros, these awards consolidate the municipal commitment to data culture, transparency and the creation of social and economic value from public information.
In this article we tell you some of the keys you must take into account to participate.
Two award categories to consider
The call establishes two categories, each with several prizes:
1) Web services, applications and visualizations: rewards projects that generate services, visualizations or web or mobile applications.
- First prize: €4,000
- Second prize: €3,000
- Third prize: €1,500
- Student prize: €1,500
2) Studies, research and ideas: focuses on research projects, analysis or description of ideas to create services, studies, visualizations, web or mobile applications. This category is also open to university end-of-degree and end-of-master's projects (TFG-TFM).
- First prize: €2,500
- Second prize: €1,500
- Third prize: €1,000
- Projects already awarded, subsidized or contracted by the Madrid City Council.
- Projects that do not use any datasets from the municipal portal.
In both categories, it is necessary that at least one set of data from the municipal portal is used, and can be combined with public or private sources from any territorial area. Projects can be recent or have been completed in the two years prior to the closing of the call.
Awards may be declared void if the minimum quality is not reached. In this case, the remaining amounts will be redistributed proportionally among the rest of the winners.
Requirements to participate
The call is open to natural and legal persons who are the authors of the projects or initiatives. The aim is for any person or entity with an interest in the reuse of data to be able to submit their proposal, regardless of their technical level.

Among them, proposals promoted by university students, startups, multidisciplinary teams and citizens committed to the intelligent use of public data stood out.
