datannur is an open source, lightweight and sovereign data catalog.

It helps organizations inventory, document and explore their data without deploying heavy infrastructure.
datannur scans files, databases and folder structures, generates structured metadata, and turns it into a portable catalog that can be opened in a browser.

The project is designed for organizations that need better data governance while keeping control over their metadata, their infrastructure and their tools.

This GitHub organization hosts the main components of the datannur ecosystem:

• datannur — the catalog interface, used to browse datasets, variables, metadata, documentation and relationships.
• datannurpy — the Python package used to scan data sources, extract metadata and build catalog-ready exports.
• swiss-open-data — the pipeline behind the public Swiss open data demo catalog.
• supporting libraries — small technical building blocks used by the project.

Most data catalog solutions are either powerful but heavy, or simple but too limited for real data governance.

datannur takes another path:

• Lightweight — no heavy server or database infrastructure required.
• Portable — can run locally, on a shared folder, on a static server or in the cloud.
• Open — open source, based on reusable metadata and designed for integration.
• Sovereign — metadata remains under the organization’s control.

datannur follows a modular architecture:

• the catalog app displays and explores metadata in the browser;
• the builder prepares, scans and exports metadata from existing data sources.

Each part can be used independently or combined into a full catalog workflow.
