Public sector data reuser´s decalogue

The "Public Sector Data Re-User´s Decalogue" (2025 edition), offers an updated guide to facilitate the access, reuse and enhancement of public sector information in the current context marked by the data economy, artificial intelligence and new European regulatory frameworks. It maintains its practical vocation, aimed at facilitating the effective reuse of public sector information by citizens, companies and administrations, but also incorporating the profound technological, regulatory and organisational changes that have taken place in the last decade.

Who it is for?

This Decalogue is aimed at a wide and diverse audience that participates, in one way or another, in the public data ecosystem. It is especially useful for public administration professionals responsible for the publication, management and governance of data; for companies, entrepreneurs and organizations that develop services, products or research based on information from the public sector; and for citizens interested in better understanding how to access, interpret and reuse these resources.

What does the guide include?

The main objective of this document is to offer a functional vision on how to leverage the value of public data in a secure, interoperable and responsible way. To do this, it clearly and concisely explains what open data is, how to interpret and apply reuse licenses, where to find datasets, and what factors influence their quality, interoperability, and persistence over time. It also incorporates an updated look at the role of metadata, standards and data governance as key elements to ensure reuse at scale and in increasingly complex contexts.

Likewise, the Decalogue presents us with the wide range of processing, analysis and visualization tools and introduces us to the need for continuous training and experimentation, in line with European priorities in digital skills and data science. In addition, it addresses the new challenges and opportunities arising from the use of data in artificial intelligence systems, placing special emphasis on its connection with the social and economic value of data and the need for ethical and responsible use through traceability, transparency and risk mitigation.

Overall, this guide is consolidated as an up-to-date and useful reference to promote a responsible, sustainable use and generator of social and economic value of public sector data.

If you want to go deeper…

For those who want to move towards more specialized levels of analytics, data science, and artificial intelligence, this guide is complemented by the Data Scientist's Decalogue, which offers a roadmap for developing high-value technical and analytical skills and continuing to deepen the best practices needed in today's data ecosystem.
