title: Preservation in the context of EOSC. Sustainable repositories curating digital objects from a long term FAIR enabling perspective
creators: Hervé L'Hours Roxanne Wyns
abstract: <p>Sustainable, interoperable, research infrastructure depends on clear standards, expectations, and delivery of services around data and metadata. To realise the long-term value of digital objects we require preservation repositories that are prepared to act to ensure they remain understandable and usable as well as discoverable and accessible.&nbsp;</p><p>The Long-Term Data Preservation Task Force (LTDP TF)[1] is working to clarify the understanding and roles of data and metadata preservation within the context of the wide range of services that form the EOSC.&nbsp;The task force vision is that the digital objects made findable and accessible through repository environments, are subject to appraisal and reappraisal over time to assess their value, impact, and associated costs. This informs the levels of storage, curation and preservation required. Not all digital objects need to be preserved, but if long term need and usage potential have been identified, then preservation can maintain and bring new value to data and metadata for their communities of users.&nbsp;</p><p>This paper explores the first set of recommendations of the task force concerning the vision, roles, finance, and role and functioning of a network of trustworthy digital repositories (TDR) in the context of preservation in EOSC. These recommendations, which incorporate the feedback collected from&nbsp;stakeholders'&nbsp;consultation beginning of 2023 in combination with the progress made on the further alignment of the FAIR principles to CoreTrustSeal[2], the definition of different curation and preservation levels[3], and CoreTrustSeal applicability to other types of (meta)data services[4], where presented at the PV2023 conference [5]. &nbsp;<br>&nbsp;</p><p>[1] <a href="https://www.eosc.eu/advisory-groups/long-term-data-preservation">https://www.eosc.eu/advisory-groups/long-term-data-preservation</a></p><p>[2]&nbsp;In the framework of the FAIR-IMPACT project&nbsp;<a href="https://fair-impact.eu/">https://fair-impact.eu/</a>&nbsp;</p><p>[3]&nbsp;CoreTrustSeal Board Discussion papers&nbsp;<a href="https://docs.google.com/document/d/17LDezbr75uSI8j-KJd5bFQ4VnlgEqY644jbux_QRrDs/edit#heading=h.gjdgxs">https://docs.google.com/document/d/17LDezbr75uSI8j-KJd5bFQ4VnlgEqY644jbux_QRrDs/edit#heading=h.gjdgxs</a> as discussed and commented on by the LTDP TF members</p><p>[4]&nbsp;Review of CoreTrustSeal&nbsp;Applicability to non-Preservation (Trustworthy) Data Services by the UK Data Service&nbsp;<a href="https://docs.google.com/document/d/1D64iut7DcBe0HYJpdhS8RA-qpEQ40daclROD4RH6DWg/edit#heading=h.gjdgxs">https://docs.google.com/document/d/1D64iut7DcBe0HYJpdhS8RA-qpEQ40daclROD4RH6DWg/edit#heading=h.gjdgxs</a>&nbsp;as discussed and commented on by the LTDP TF members</p><p>[5] PV2023 conference <a href="https://indico.cern.ch/event/1188041/">https://indico.cern.ch/event/1188041/</a></p>
