Curation Policy
This list follows the [Open Definition](https://opendefinition.org/): data must permit free use, modification, and redistribution, including commercial reuse. Tools must publish their source code under an [OSI-approved license](https://opensource.org/licenses). Related guides, communities, and media must be freely accessible, directly relevant, and operated by an official institution, established non-profit, research organization, or transparent community project.
Registration is acceptable when it is free and non-discriminatory, but payment, case-by-case permission, non-commercial-only terms, or unclear reuse rights are exclusion criteria for data and tools.
Repositories and catalogs that contain both open and restricted records are clearly identified. Always verify the license of an individual dataset before reuse.

Contribute
Contributions are welcome through issues and pull requests. A proposed resource should:
- focus on Switzerland or provide clear value for Swiss comparisons;
- identify its publisher, primary access URL, and, for data or tools, license or reuse terms;
- permit free use, modification, and redistribution, including commercial reuse, when it provides data;
- provide machine-readable data or, when it is a tool, source code under an OSI-approved license;
- be maintained by an official institution, established non-profit, research organization, or transparent community project; and
- avoid duplicating a more direct or authoritative entry already on the list.
Catalogs containing restricted records must say so explicitly. Free-to-view services, non-commercial-only APIs, proprietary applications without reusable data, and resources with unclear licensing are out of scope.
