TrustRelay is a platform for data ecosystems from Beyond Civic AG in Lucerne, Switzerland. Organisations share data there as data products: a catalogue makes them discoverable, participants are invited and approved through membership management, and access runs through requests with a purpose and duration that the owner approves and can monitor. A federated query engine based on DuckDB queries sources such as PostgreSQL, MySQL, SQLite, cloud storage, APIs and files like CSV and Parquet using SQL. Metadata follows open standards, including the Open Data Product Specification and Croissant. Beyond Civic also offers consulting.
Beyond Civic AG is headquartered in Lucerne, and the sources name no foreign parent company. The pages consulted do not state whether TrustRelay is delivered as SaaS or on your own infrastructure, or where data is hosted, so ask the vendor. An open-source licence for the product has not been established. Switzerland is not an EU member but an EFTA country with an EU adequacy decision, so transfers of personal data from the EU rest on a recognised basis.
