The International Data Spaces Association (IDSA) has published an ISD reference testbed that has been jointly developed by the IDSA open-source community. Data spaces are key to trusted data sharing in the global data economy. The technical components of data spaces need to be tested and certified to enable trusted data sharing in industry verticals. The IDS reference testbed is a tool for the development of IDS-compliant components and testing of their interoperability in preparation for the IDS certification. The testbed is open source and publicly available. Read more on the IDSA webpage and discover the testbed on GitHub.
