The report Open Data Maturity (ODM) 2025, published by the European Data Portal, places Spain among the leaders in the opening and reuse of public sector information, consolidating an upward trajectory in digital innovation. The 2025 Open Data Maturity (ODM) assessment analyses the level of maturity of countries in the field of open data. Specifically, the assessment measures the progress of European countries in making public sector information available and stimulating its reuse, in line with the Open Data Directive (Directive (EU) 2019/1024) .
In total, 36 countries participated in this 11th consecutive annual assessment, including the 27 EU Member States, 3 European Free Trade Association countries (Iceland, Norway and Switzerland) and 6 candidate countries (Albania, Bosnia and Herzegovina, Montenegro, North Macedonia, Serbia and Ukraine).
Spain reaches 95,6% maturity (0,8% more than the previous year), placing it among the countries with the highest level of development in open data. It occupies the fifth position among EU countries and the sixth of the total number of countries analyzed, tied with Italy. It continues to be within the group of trendsetter countries, with advanced ecosystems and fully aligned with the European data strategy.
Four dimensions of analysis
The assessment methodology defines open data maturity (ODM) using four dimensions:
Politics: analyzes existing open data policies and strategies in participating countries, national governance models for managing open data, and measures applied to implement these policies and strategies.
Portal: analyzes the functionality of national open data portals, the degree to which user needs and behavior are examined to improve the portal, the availability of open data in different areas, and the approach to ensuring the sustainability of the portal.
Quality: evaluates the measures adopted by portal managers to guarantee the systematic collection of metadata, the monitoring of metadata quality and compliance with the DCAT-AP metadata standard, as well as the quality of the deployment of data published on the national portal.
Impact: analyzes the willingness, readiness and capacity of countries to measure both the reuse of open data and the impact generated through this reuse.
Of the four dimensions analyzed, Spain stands out especially in the “Impact” dimension, where it achieves the highest score: 100% compared to 82,1% of EU27 countries. In the other dimensions, Spain scores above the average for EU countries: 99,2% compared to 93,1% in Policy; 95,5% compared to 85,4% in Portal; and 87,8% compared to 83,4% in Quality.
