Data from the Confederation, cantons, municipalities and other organisations with a mandate from the state can be published on LINDAS. Since LINDAS is still in build-up mode, the Federal Archives are currently only publishing selected datasets on the platform.
Register at email@example.com if you are interested in publishing data on LINDAS.
Data Cubes (see https://cube.link/) are a specific form of data in OLAP like cubes which can be consumed by a multitude of tools, eg. https://visualize.admin.ch/. For data to be compatible with the different tools some additional requirements might be necessary.
