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. Therefore, both professionals and companies, researchers, journalists and developers, as well as amateurs and amateurs interested in data analysis and visualization can participate.

SUBSIDIA ONERIS (Latin for “burden of subsidies”) is a library of applets that enable mass access to data from the National Subsidies Database portal directly from Excel, using PowerQuery ETL to access the official SNPSAP API. It is shared under a CC BY-NC-SA 4.0 license.

Its use requires only very basic knowledge of Excel. The available applets are as follows:

• De minimis Inspector 2.0: By entering one or multiple tax identification numbers (NIF) of beneficiaries, it returns all de minimis grants existing on the Portal on the date the query is performed, granted over the previous three years, providing transactional information on these grants as well as various aggregates and reports. Useful for checking compliance with the three-year de minimis accumulation requirements per beneficiary established in the applicable European regulations.

• State Aid (AdE) Inspector 2.1: By entering one or multiple beneficiary NIFs, it returns all State Aid grants existing on the Portal on the date the query is performed, providing transactional information on these grants as well as various aggregates and reports.

• All Grants Inspector 2.0: By entering one or multiple beneficiary NIFs, it returns all grants existing in the “All” tab of the Portal on the date the query is performed, providing transactional information on these grants as well as various aggregates and reports.

• Grants by Date Query Tool (more than 10,000) 2.1: By entering a start and end date, it returns all grants existing in the “Grants – All” tab of the Portal for the reference period on the date the query is performed, providing transactional information as well as various aggregates and reports. Time intervals should preferably not exceed one month, as the large number of grants may cause the download to fail, depending on the memory resources of the computer running Excel and the transactional load on the servers.

• Grants by Call for Proposals Query Tool (more than 10,000) 2.1: For calls for proposals that have more than 10,000 grants, this tool allows downloading all of them, up to 1,000,000 grants. Only one call code can be specified.

• State Aid by Date Query Tool (more than 10,000) 2.1: By entering a start and end date, it returns all grants existing in the “State Aid” tab of the Portal for the reference period on the date the query is performed, providing transactional information as well as various aggregates and reports. Time intervals should preferably not exceed one year, as the large number of grants may cause the download to fail, depending on the memory resources of the computer running Excel and the transactional load on the servers.

• De minimis by Date Query Tool (more than 10,000) 2.1: By entering a start and end date, it returns all grants existing in the de minimis tab of the Portal for the reference period on the date the query is performed, providing transactional information as well as various aggregates and reports. Time intervals should preferably not exceed one year, as the large number of grants may cause the download to fail, depending on the memory resources of the computer running Excel and the transactional load on the servers.

• Multi-SA State Aid Query Tool (less than 10,000) 2.0: By entering one or multiple references to State Aid measures (SA.number), it returns all State Aid grants existing on the Portal on the date the query is performed for those measures, providing transactional information as well as various aggregates and reports. If any measure (SA.number) has more than 10,000 grants, only the first 10,000 are downloaded, so it should not be used in that case. If an SA has more than 10,000 grants, the Multi-code Grants by Call Query Tool can be used instead. To do so, you must first identify the calls for proposals that have been formalized for that SA measure.

• Multi-code Grants by Call Query Tool (less than 10,000) 2.1: By entering one or multiple BDNS call codes, it returns all grants for those calls existing on the Portal on the date the query is performed, providing transactional information as well as various aggregates and reports.

If any call has more than 10,000 grants, it only downloads the first 10,000, so it should not be … (text truncated in the original).

The Cabildo Insular de Tenerife has announced the II Open Data Contest: Development of APPs, an initiative that rewards the creation of web and mobile applications that take advantage of the datasets available on its datos.tenerife.es portal. This call represents a new opportunity for developers, entrepreneurs and innovative entities that want to transform public information into digital solutions of value for society. In this post, we tell you the details about the competition.

A growing ecosystem: from ideas to applications

This initiative is part of the Cabildo de Tenerife's Open Data project, which promotes transparency, citizen participation and the generation of economic and social value through the reuse of public information.

The Cabildo has designed a strategy in two phases:

• The I Open Data Contest: Reuse Ideas (already held) focused on identifying creative proposals.

• The II Contest: Development of PPPs (current call) that gives continuity to the process and seeks to materialize ideas in functional applications.

This progressive approach makes it possible to build an innovation ecosystem that accompanies participants from conceptualization to the complete development of digital solutions.

The objective is to promote the creation of digital products and services that generate social and economic impact, while identifying new opportunities for innovation and entrepreneurship in the field of open data.

Awards and financial endowment

This contest has a total endowment of 6,000 euros distributed in three prizes:

• First prize: 3,000 euros

• Second prize: 2,000 euros

• Third prize: 1,000 euros

Who can participate?

The call is open to:

• Natural persons: individual developers, designers, students, or anyone interested in the reuse of open data.

• Legal entities: startups, technology companies, cooperatives, associations or other entities.

What kind of applications can be submitted?

Proposals must be web or mobile applications that use at least one dataset from the datos.tenerife.es portal. Some ideas that can serve as inspiration are:

• Applications to optimize transport and mobility on the island.

• Tools for visualising tourism or environmental data.

• Real-time citizen information services.

• Solutions to improve accessibility and social participation.

• Economic or demographic data analysis platforms.

Evaluation criteria: what does the jury assess?

The jury will evaluate the proposals considering the following criteria:

• Use of open data: degree of exploitation and integration of the datasets available in the portal.

• Impact and usefulness: value that the application brings to society, ability to solve real problems or improve existing services.

• Innovation and creativity: originality of the proposal and innovative nature of the proposed solution.

• Technical quality: code robustness, good programming practices, scalability and maintainability of the application.

• Design and usability: user experience (UX), attractive and intuitive visual design, guarantee of digital accessibility on Android and iOS devices.

The complete bases and the official application form are available at the Cabildo's Electronic Office.

With this second call, the Cabildo de Tenerife consolidates its commitment to transparency, the reuse of public information and the creation of a digital innovation ecosystem. Initiatives like this demonstrate how open data can become a catalyst for entrepreneurship, citizen participation, and local economic development.

Open SDG Index is a platform for managing and visualising results and progress in the fulfilment of the Sustainable Development Goals and the 2030 Agenda. It allows reporting and systematizing the progress and effort made by public and private entities to meet the SDGs. On the one hand, it facilitates the self-evaluation of this progress and, on the other, it makes the results known to the general public. It is part of the SDG system and allows any entity to incorporate and update its profile. 

The portal includes advanced searches, sectoral and territorial filters and organisation profiles for open consultation. The information is verified by independent agents and presented geolocalized to facilitate comparison between organizations and territories.

For the deployment of the Open SDG Index, a proprietary methodology has been developed in collaboration with the UNDP (United Nations Development Programme). The project won the First Prize for Social Entrepreneurship "La Noria" from the Diputación de Málaga in 2020.

The Smart Agro – Irrigation Recommendations website is a free platform developed by the Cabildo de La Palma as part of the La Palma Smart Island project. It aims to improve the efficiency of water use in local agriculture, especially for banana and avocado crops.

To get a personalized recommendation, the user must select a crop and an area of the island through a drop-down menu or on the map. Instead, the app:

• It provides detailed graphs showing the recent evolution of precipitation and evapotranspiration (ETo) over the past 7 days in the selected area.
• It generates irrigation recommendations adjusted to the municipality and local climatic conditions.

To carry out the calculations, data from the island's network of weather and air quality stations are used, together with a calculation engine that processes the information to generate weekly recommendations. Likewise, the data generated by this engine is integrated into the open data portal, promoting an open innovation ecosystem that feeds back on each other.

CLIMA TERRA is a progressive web application (PWA) that provides real-time environmental information in a clear and accessible way. It allows users to view key parameters such as temperature, relative humidity, wind speed and UV index, based on open meteorological and geospatial data.
The app has been designed with a minimalist and bilingual (Spanish/English) approach, with the aim of bringing open data closer to the public and promoting more informed and sustainable everyday decisions.

  MOVACTIVA is a digital platform developed by the Department of Geography of the Universitat Autònoma de Barcelona, which works as an interactive atlas focused on active mobility, i.e. the transport of people using non-motorised means, such as walking or cycling. The atlas collects information from five Spanish cities: Barcelona, Granada, Madrid, Palma de Mallorca and Valencia.

The project maps five urban indicators that are decisive for active mobility, based on 57 georeferenced variables:

• Urban densities for walkability
• Cyclability
• Presence of green spaces
• Urban vitality
• 15-minute city

The combination of these five elements makes it possible to create an objective and standardised indicator: the Global Active Mobility Indicator. 

In addition, the website also offers information on:

• Micromobility, which includes electric, small and light modes of transport (Personal Mobility Vehicles or PMVs), such as electric bicycles and scooters, hoverboards, segways and monowheels.
• Intermodality, which involves the use of two or more modes of transport within the framework of a single trip.

To bring information closer to users, it has an interactive viewer that allows geographic data to be explored visually, facilitating comparison between cities and promoting a healthier and more sustainable urban approach. The indicators are superimposed on open access base maps such as the PNOA orthophotography (from the IGN) and OpenStreetMap.
