What doesnt kill us The impact of DPNs

What doesn’t kill us The impact of DPN’s downfall on the nodes

Friedrich Nietzsche, the ^problematic German philosopher, famously said: "That which does not kill us makes us stronger. ". . this panel attempts to answer ‘does it? ’

● Chronopolis was started in early 2000’s and initially funded by Library of Congress NDIIPP grants in mid-2000’s. ● Production launched in 2008. ● Three nodes in three different US regions ● TRAC audit received in 2012. ● Software is all open source. ● About 100 TB in data in the regular network, mostly from UCSD. ● 120 TB allocated to DPN with ~27 DPN members depositing through Dura. Cloud Vault

● ● ● LYRASIS hosted digital preservation service Open source software project Lo. C funded in 2009, production launch in 2011 Storage in: Amazon S 3, Amazon Glacier, Chronopolis Any type of file, any size, any number

DPN Timeline 2012 Original concept announced; founding members 2013 The Case for Building a Digital Preservation Network (Educause Review); tech development 2014 First new DPN staff added 2015 Deposit/ingest tested 2016 First “production” status; ingest via two nodes 2017 Full production status; ingest continues; planned services expand 2018 Exanode finalized; scale of deposit doesn’t sustain business model; shutdown decision made 2019 Content disposition set; DPN Final Report published

DPN Goals 2013 (source: Educause Review Case Statement) “The Archive for Archives” • Resilience (safety net of multiple independently operated repositories; interoperability bridge) • Succession (enable future use by the academy) • Economies of scale • Efficiency (network of proven repositories) • Extensibility (business, technical and legal framework capable of evolving over time) • Security (best practices approach)

How did DPN explain the closure? • Time to market too long (and dev costs too large) – Needs changed, Engagement model not addressed early enough • Institutions not ready to deposit • Legal documents cumbersome and expensive • No single accepted preservation model; competition with campus infrastructures • Members stopped at free storage level • Competition with nodes • Endowment sustainability model never happened • Membership decline • No time to build investment-worthy interim plan

From your perspective, why did the DPN model fail?

Describe what happened at your node after the shutdown of DPN. How did your members/users react? How has DPN’s shutdown impacted your team/community/institution?

What are some elements of a sustainable DDP? What needs to live on from this work? What did we learn?
