<p>On 21-23 March 2023, the <a href="https://internationaldataspaces.org/data-spaces-symposium/" target="_blank">International Data Spaces Symposium</a> brought together the diverse landscape of data space initiatives together, to learn from successfully mature data space projects, discover the business benefits of utilising sovereign data sharing and, ultimate, to co-create the future of data spaces.</p>
<p>The Commission presented the Once-Only Technical System and eDelivery in a <a href="https://twitter.com/EU_OnceOnly/status/1638205032632926208/" target="_blank">lightning pitch</a> and info stand within the event’s exhibition area.</p>
<p>On 23 March 2023, the European Commission organised a panel discussion looking at the <a href="https://ec.europa.eu/digital-building-blocks/sites/display/OOTS/About+OOTS/" target="_blank">Once-Only Technical System</a> (a recognised data space) and how the <a href="https://ec.europa.eu/digital-building-blocks/sites/display/DIGITAL/eDelivery/" target="_blank">eDelivery Building Block</a> contributes to the Once-Only architecture.</p>
<p>The Once-Only Technical System connects EU public authorities, so they can exchange official documents and data at the citizen’s request. It puts into practice the Once-Only Principle, which states that citizens should not be forced to provide information to authorities if another authority already holds that information in electronic format.</p>
<p>Audience questions discussed, among other things, the scope of the Once-Only data space (defined in the relevant Regulation) and GDPR compliance (where data exchanged through the Once-Only Technical System is subject to the retention policy faced by any organisation accessing personal data).</p>
<p>eDelivery provides technical specifications and standards, installable software and ancillary services to allow projects to create a network of nodes for secure digital data exchange. By building with eDelivery, public and private organisations from different sectors can easily create a safe and interoperable channel to transfer documents and data among each other over a public or private network.</p>
<p>The Once-Only Technical System reuses eDelivery or the exchange of evidences within the system. Member States are free to choose how many eDelivery access points they use in their Once-Only Technical System architecture. Member States may choose to deploy one access point for the Once-Only Technical System, one per region, one per sector or any other configuration that makes most sense for their country.</p>
<p>This event was a milestone for data spaces in Europe, hosted by the Center of Excellence for Data Sharing and Cloud (TNO), International Data Spaces Association, the Basic Data Infrastructure network and the Data Spaces Support Centre, supported by the Data Spaces Business Alliance, organised together with EUHubs4Data and MyData Global.</p>
<p>Visit the <a href="https://ec.europa.eu/digital-building-blocks/sites/display/OOTS/About+OOTS/" target="_blank">Once-Only Hub</a> to learn more about the Once-Only Technical System and how data is enabling citizens and businesses to take even greater advantage of the European Single Market.</p> |
