<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 projectseach other, discovershare theinformation businessabout benefitsreusable ofcomponents utilisingand sovereign data sharing and, ultimate, totechnical specifications, ultimately co-createcreating the future of data spaces.</p>

<p>On 23 March 2023, the European Commission organised a panel discussion looking at deep dive on the data space of European authentic data sources known as 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<a href="https://twitter.com/EU_OnceOnly/status/1638205032632926208" target="_blank">lightning pitch</a> and an info stand, together with the <a href="https://ec.europa.eu/digital-building-blocks/sites/display/DIGITAL/eDelivery/" target="_blank">eDelivery Building Block</a>, contributeswithin tothe theevent’s Once-Onlyexhibition architecturearea.</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 enables data sharing from authentic data sources such as population registers, vehicles registers, business registers, etc. with government websites and apps from across Europe. This dataspace enables cross-border Once-Only Principleadministrative procedures, which states that citizens shouldmay notrequest bethe forcedretrieval toof providedata informationfrom tothe authoritiesauthentic ifdata anothersources authorityholding alreadyit holdsin thatother informationMember in electronic format.</p>
<p>AudienceStates. Audience questions discussed, among other things, the scope of the Once-Only data space (defined in the relevant Regulation <a href="https://single-market-economy.ec.europa.eu/single-market/single-digital-gateway_en" target="_blank">Single Digital Gateway Regulation</a>) and GDPR compliance (where data exchanged through the.</p>
<p>The discussions with other dataspaces showed two unique characteristics of Once-Only Technical System is subject to the retention policy faced by any organisation accessing personal data).</p>
<p>eDelivery:</p>
<ul>
<li>The Once Only dataspace enables access to authentic data in everyday cross-border scenarios: registering an address or a car in another Member State, opening a branch in another Member State, etc.;</li>
<li>The Once Only dataspace is composed by “Lego-like” building blocks based on open-standards and aligned with EU Regulations such as <a href="https://ec.europa.eu/digital-building-blocks/sites/display/DIGITAL/eID" target="_blank">eID</a>, <a href="https://ec.europa.eu/digital-building-blocks/sites/display/DIGITAL/eDelivery" target="_blank">eDelivery</a> and <a href="https://ec.europa.eu/digital-building-blocks/sites/display/DIGITAL/eSignature" target="_blank">eSignature</a>. For example, 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 transfershare 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>li>

<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>
