1. Reshaping Preserv 2 from a Life(cycle) perspective Steve Hitchcock and Dave Tarrant Preserv 2 Project School of Electronics and Computer Science (ECS), Southampton University JISC Digital Curation and Preservation Projects Forum Placing Ourselves in the Bigger Picture 30 June 2008, Birkbeck College, London

2. Some tricky questions Q1 What is digital preservation? A ? But, from summary of LIFE2 conference: We have been presented with reports from a number of Case Studies … seems to suggest that we are still learning what digital preservation means in practice Q2 Who wants digital preservation? A ? Q3 When is preservation not preservation? A e.g. when its storage or interoperability

3. Digital preservation as an intangible asset Laurie Hunter digital preservation is a selective preservation of an intangible asset that has a reasonable probability of producing benefits at some future time. In that sense, digital preservation decisions are investment decisions … Hence, appropriability, the nature of the market for preserved data, its pricing and timescale or life-cycle, are all important issues which need to be addressed. http://www.dcc.ac.uk/docs/Wksppaper.pdf Understand the needs of the market, but what if the market doesnt understand the product in the first place?

4. Definitions of digital preservation Digital preservation combines policies, strategies and actions that ensure access to digital content over time. Digital preservation combines policies, strategies and actions to ensure access to reformatted and born digital content regardless of the challenges of media failure and technological change. The goal of digital preservation is the accurate rendering of authenticated content over time. Digital preservation combines policies, strategies and actions to ensure the accurate rendering of authenticated content over time, regardless of the challenges of media failure and technological change. Digital preservation applies to both born digital and reformatted content. Digital preservation policies document an organizations commitment to preserve digital content for future use; specify file formats to be preserved and the level of preservation to be provided; and ensure compliance with standards and best practices for responsible stewardship of digital information. Digital preservation strategies and actions address content creation, integrity and maintenance….

7. Preservation costs Neil Beagrie, et al. Keeping Research Data Safe: A Cost Model and Guidance for UK Universities http://www.jisc.ac.uk/publications/publications/keepingresearchdatasafe.aspx LIFE2, applying a whole-business approach, including overheads; moving towards a ROI-based method (LIFE3?) there is one question everyone needs to ask - how much can you afford to pay? David Rosenthal, DCC-associates list, 26 June One-size cost model does not fit all

15. Repository preservation service providers Start of Preserv (2005) Preservation services, e.g. National libraries Institutional services Repository software Manue.fig

16. Repository preservation service providers Today Preservation services, e.g. –KB-NARCIS (Dutch portal, includes DARE IRs) –German National Library (theses) –BL (UK PubMed Central) –Sherpa-DP Institutional services, e.g. Oxford Repository software Repository services Library services, e.g. OCLC Cloud storage services, e.g. Amazon, Google

17. Preserv 2 today Preserv has evolved More focussed on enabling the infrastructure for a full and diverse range of preservation services required by the market A project, not a service provider Project partners, singly or jointly, might emerge as different types of preservation service provider Let many preservation service providers flourish
