A Spanish example of public data reuse: The case of OpenMercantil
OpenMercantil is a Spanish initiative that demonstrates how public
data can be reused to make mercantile and company information more
accessible for a wide audience. By bringing together data from public
sources into a single platform, it allows users to search, explore,
and better understand company activities. This creates an access data
ecosystem, supporting transparency, informed decision-making and
public trust in the economy. 

Through the OpenMercantil project website [https://openmercantil.es/],
users can access company pages, structured event timelines, and
detailed source notes that explain where the data comes from. The
platform also offers downloadable datasets
[https://openmercantil.es/descargas] and a well-documented application
programming interface (API
[https://openmercantil.es/api/documentacion]), making it easier for
developers and analysts to integrate and reuse the information. More
importantly, OpenMercantil is an independent information service and
is not an official source such as the Boletin Oficial del Estado.
Therefore, it does not replace certified legal documents and has its
own unique contribution. 

The use case highlights the value of open data by showing how public
sector information can be transformed into practical tools that
benefit multiple communities. By combining the tool’s usability
features such as timeless and machine-readable formation with
transparency about data sources [https://openmercantil.es/fuentes],
the platform supports innovation and fosters new services in areas
like procurement, data journalism, and public interest analysis. 

To explore how public data can be reused in practice, visit the
OpenMercantil platform [https://openmercantil.es/] and browse its
OpenAPI specification page [https://openmercantil.es/openapi.json].
Discover how open data can unlock insights and empower your work.
