Challenges
Why making the most of data has become a public-service issue
Opening data is not enough. It has to be findable, understandable and usable by the people who need it.
Scattered, poorly documented data
The data exists, but it is spread across departments, formats and tools. Finding, understanding and combining it still takes too much effort.
Decisions without shared indicators
Each department produces its own figures. Without a common reference, officials, staff and partners do not read the same territory.
Audiences kept at a distance
Citizens, associations, businesses: many give up when faced with raw files. Access to data should become a conversation.
The platform
One platform, five dimensions
Data4Citizen brings together, in one coherent whole, open data, analysis, artificial intelligence, community and service creation.
Open Data
Open up and share
Make data available in a clear, documented and reusable way: catalogues, licences, open formats and APIs.
Data Intelligence
Understand and decide
Combine, analyse and visualise data to produce indicators that support decision-making and the steering of public policies.
Artificial intelligence
Talk to your data
Query data in natural language, get answers with their sources, and get help finding and understanding datasets.
Ecosystem and community
Contribute together
Share experience, contributions, innovations and good practice between organisations, developers and citizens.
Digital services
Build services
Develop data portals, observatories and services for citizens, public servants and professionals.

Technologies
An open approach, built on proven components
The platform is part of an open technology ecosystem. Depending on the project, it can rely on well-known components without imposing a single architecture.
- CKAN
- Open data catalogue, the reference for Open Data portals.
- Drupal
- Content management for portals and observatories.
- Python
- Data processing, analysis and automation.
- Jupyter
- Interactive notebooks to explore, analyse and share data.
- Large language models (LLM)
- Natural-language interaction and user assistance.
- PostgreSQL
- Robust relational database for storage and computation.
- Data APIs
- Programmatic access and interoperability with other systems.
Not every installation uses all of these technologies: it depends on the needs and context of each project.
