Open Government, Luxembourg

About Open Government, Luxembourg

data.public.lu is the official open data portal of the Government of Luxembourg, publishing datasets from national administrations, municipalities, and public institutions. The platform hosts thousands of datasets covering topics including geospatial data, meteorology, statistics, mobility, environment, and business, contributed by organizations such as the Administration du cadastre et de la topographie, STATEC, MeteoLux, and the Musée national d'histoire naturelle. Datasets can be downloaded, and an API is available for programmatic access to some sources, such as the LUSTAT statistical database and the Lëtzebuerger Online Dictionnaire.

The site also catalogs "reuses" — applications, visualizations, and APIs built by third parties on top of the published data, including tools for tracking vehicle fleets, mapping libraries, exploring legal texts, and flood warning systems. Users can register accounts to publish their own datasets or reuses, and organizations can create profiles to manage their published data.

The portal is aimed at developers, researchers, public administrations, and civic organizations working with Luxembourgish public data. It is built on the udata platform and content is released under a Creative Commons CC0 license.
