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 project mode, the Federal Archives are currently only publishing selected datasets on the platform.
Register at firstname.lastname@example.org 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.
