<p>On 21-23 March 2023, the International <a href="https://internationaldataspaces.org/data-spaces-symposium/" target="_blank">International Data Spaces SymposiumSymposium</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>The CommissionIn presented the Once-Only Technical System and eDelov in a lightning pitch and info stand within the event’s exhibition area.<p>
<p>On 23 March 2023this context, the European Commission organiseddelivered a paneldeep discussiondive lookingon at the Once-Only Technical System (a recognised data space) and how the eDelivery Building Block contributes to the Once-Only architecture.<p>
<p>On 21 February 2023, the European Commission organised the fourth instalment in the 2022-2023 OOTS Implementers’ Café webinar series. </p>
<p><a of European authentic data sources known as the <a href="https://ec.europa.eu/digital-building-blocks/sites/display/OOTS/About+OOTS" target="_blank">The Once>Once-Only Technical System (OOTS)<System</a> connects EU public authorities, soa 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>The first part of this online event looked at evidence exchange from a UX perspective<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>, within the event’s exhibition area.</p>
<p>The openingOnce-Only presentationTechnical consideredSystem aenables fictionaldata example.sharing Forfrom theauthentic preposesdata of explaining the ‘Once-Only’ user experience, a character is defined as having a nationality (Italian), to have competed secondary school in Italy, have moved to Belgium, where she completed a bachelor's degree and got married. She is also defined as disabled and wants to <strong>apply for a study grant</strong> from Germany.</p>
<p>To complete this procedure, the relevant German online portal would ask the user to provide several evidences (in this case, secondary school diploma, bachelor's degree, marriage certificate and disability certificate), to be accessed throughsources such as population registers, vehicles registers, business registers, etc. with government websites and apps from across Europe. This dataspace enables cross-border Once-Only administrative procedures, which states that citizens may request the retrieval of data from the authentic data sources holding it in other Member States. Audience questions discussed, among other things, the scope of the Once-Only Technical System.</p>
<p>This example therefore explored evidence requesting and evidence location through the Once-Only Technical Systemdata space (defined in the relevant <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.</p>
<p>Experts<p>The fromdiscussions thewith Commissionother thendataspaces movedshowed totwo discussunique ‘OOTS common services’. These are interoperability solutions that are necessary for the proper execution of the evidence exchange process within the Once-Only system.</p>
<p>During this Implementers’ Café, experts from the Commission presented two OOTS common servicescharacteristics of Once-Only:</p>
<ul>
<li>The <strong>DataOnce ServiceOnly Directory (DSD)</strong>, a catalogue of Evidence types that the evidence providers can provide upon request. It is used in the Evidence Exchange process by the evidence requesters to discover the evidence providers that can provide the evidence they require; and</li>
<li>The <strong>Evidence Broker (EB)</strong>, an authoritative system that maps specific data sets as evidence types that prove specific requirements. The evidence requester consults the EB to find which types of evidence can be requested as evidence for a specific Evidence Subject, taking into account the subject's location and/or jurisdiction.</li>
</ul>
<p>The Semantic Repository (SR) is another common service, which acts as a data portal for the technical system and is currently still in development. This will be explored in a future Implementers’ Café.</p>
<p>In addition to the OOTS common services, the European Commission and Member States have further developed a 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/OOTS/Catalogue+of+reusable+servicesDIGITAL/eID" target="_blank">catalogue of reusable services</a> including:</p>
<ul>
<li>e-Government <strong>Core Vocabularies</strong>: simplified, reusable and extensible data models that capture the fundamental characteristics of a data entity in a context-neutral fashion</li>
<li>Various <strong>testing services</strong> and resources;</li>
<li>The >eID</a>, <a href="https://ec.europa.eu/digital-building-blocks/sites/display/DIGITAL/eDelivery" target="_blank">eDelivery</a> <strong>building block</strong>, a package of technical specifications based on open standards to allow Member States to create a network of nodes for secure digital data exchange;</li>
<li>The and <a href="https://ec.europa.eu/digital-building-blocks/sites/display/DIGITAL/eIDeSignature" target="_blank">eIDAS eID<>eSignature</a>. For <strong>building block</strong> for cross-border authentication.</li>
</ul>
<p>As with previous Implementers’ Cafés, the second half of the event specifically addressed the preparation of the 2023 OOTS Projectathon series.</p>
<p>The OOTS Projectathons enable national teams to pair up with others to run tests, using different actors, roles and testable profiles to check the status of their Once-Only Technical System implementation. The first Projectathon takes place in April 2023.</p>
<p>Participation in Projectathons is specifically for national implementation teams working on the implementation of the Once-Only system.</p>
<p>Participants learnt about the Projectathon registration processes and an <strong>overview of the test scenarios</strong> that will be explored during the Projectathon.</p>
<p>Have a look atexample, 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 share documents and data among each other over a public or private network.</li>
</ul>
<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>
