datannur

datannur is an open-source data catalog that runs entirely from static files — no server, no database, no installation. A Python builder scans your data sources (CSV, Excel, Parquet, SAS/SPSS/Stata, geospatial formats, and databases such as PostgreSQL, MySQL, Oracle, SQL Server, SQLite or DuckDB), extracts the metadata and generates a portable, read-only catalog that opens in any browser, even from a plain local folder, a shared drive, an intranet or object storage.

The catalog organizes metadata around organizations, folders, datasets, variables, tags, concepts, docs and enumerations, with search, dataset previews, descriptive statistics, variable-level profiling and data quality indicators. Geospatial datasets are supported (coordinate system, bounding box, geometry type), with metadata export to open standards such as DCAT. An optional AI assistant can be enabled with your own API key.

Because the output is just static files, access control stays where the files are hosted (drive ACLs, intranet auth, web server rules). The interface is available in English, French, German and Italian. MIT-licensed, and running in production in a Swiss cantonal statistical office for over two years.
