Context

Once-Only means a simpler, more resilient digital environment in Europe. The Once-Only Technical System lets EU public authorities securely exchange official documents and data at the request of citizens and businesses as part of cross-border administrative procedures, e.g., when registering an address or vehicle when moving abroad.

As we move through different stages of life, we create a “data chain”, consisting of official records of our most important life events, stored in public registers. These official data sets, held in public registers, are the foundation of modern societies and are used in all types of daily transactions. However, when life takes you across European borders your data sets become more fragmented and difficult to access. In this way, the more you benefit from the four freedoms Europe offers, as a person or a business, the more difficult it is to interact with public administrations.

The Once-Only Technical System is the missing link, it creates your European Data chain.

As a large-scale European initiative, Once-Only is a federated system built on sound sovereignty principles. This means that the technology design prioritises open specifications based on international standards. It emphasis decentralisation, user control, and long-term sustainability. This ensures that there is no dependency on a single company or entity but allows large and small players, from in and outside the EU, to participate in its creation. In other words, sovereign software should be platform-agnostic and multi-vendor, designed for multi-cloud provider deployments, combined with robust security controls.
