datannur

The open-source, lightweight, and sovereign data catalog

About datannur

datannur is a lightweight, open-source data catalog for documenting and exploring structured data files and databases. It scans data sources and generates a structured, interoperable catalog under the organization's own control, helping teams inventory sources, document variables, and check quality before publication, business intelligence, or AI use. Developed in Switzerland and used by a cantonal statistical office, it targets organizations that find large governance platforms too cumbersome or expensive.
