1 IRs: towards preservation services Steve Hitchcock Preserv Project Intelligence Agents Multimedia Group, School of Electronics and Computer Science (ECS), Southampton University JISC Repositories & Preservation Programme, New Projects Briefing London, October 2006

2 Preserv: a rapid sketch 1.Preserv is investigating preservation strategies for institutional repositories 2.Repositories (or repository software) do not do preservation 3.IR preservation must begin with IR policy 4.Digital preservation is difficult and best managed by specialists – preservation service providers 5.We dont know what a preservation service provider looks like

3 IR software EPrints (Southampton) DSpace (MIT) Fedora (Cornell, Virginia) These are among the most widely used applications for building IRs. It can be argued that these provide different degrees of support for preservation (in reverse order!).

4 IR software as preservation system (N)o existing software application could serve on its own as a trustworthy preservation system. … Without the appropriate people, infrastructure, policies, and procedures, even the best preservation application cannot ensure preservation. Fedora and the Preservation of University Records Project: Reports and Findings, Tufts University and Yale University, Final Narrative Report to NHPRC, September 27, 2006

5 Preservation actions Storage media Media refreshing Reformatting Backups and disaster recovery Environment Audit Security Preservation strategy Migration Emulation Technology preservation Records management, etc. From the JISC standards guidelines

6 Preservation as policy IR preservation must start with policy IR policy is concerned with all aspects of repository management: content strategy (mandates!), collection policy, rights, etc., see OpenDOAR Policies Tool Preservation strategy will emerge from this analysis BUT IRs can only know the requirements and scale of the preservation task with a fully formed policy To fulfil institutional requirements, the policy needs institutional backing (a true IR)

7 Survey of repository policies Selected repository administrators invited to participate, based on availability and size of ROAR profile Original test sites for profiling and survey included Oxford University, e-Prints Soton, ECS EPrints (Soton) Series of questions, based on analysis of preservation metadata for Preserv model EPrintsDSpaceBoth Accepted/sent22112 Returned1342

8 Does the repository have any existing policy on preservation? Yes 1 No 18 Example policy

9 Does the repository implement any preservation measures, internally or with external agents/services? Byte preservation Y 8 N 9 No reply 2 Transformation Y 3 N 14 No reply 2 Rendering Y 1 N 13 No reply 5 Emulation Y 0 N 14 No reply 5 Other: backup, mirroring, geographic cluster backup Partnerships: Sherpa-DP, MetaArchive NDIIPP, dissertation copies at German National Library

10 Does the repository have a policy on submission file formats? Y 11 N 4 No reply 4 prefer PDF / DOC / PPT / HTML recommend using PDF or HTML PDF (Sherpa policy) accept all formats, text documents should be at least be pdf preferred pdf/a Use DSpace supported, known, and unknown formats (x3) Rendering software must be free, i.e. Acrobat, text, PostScript, HTML

12 Format profiling using PRONOM and ROAR ROAR

13 Preservation services: passive to active 1.Passive preservation (aka bitstream preservation) 2.Active preservation 1.Characterisation 2.Preservation planning 3.Preservation action

14 Moving to a new concept: distributed preservation services? We need to look beyond the idea of a black box preservation service Services might be based on lightweight, interacting distributed Web services Who will provide these services? What coordination is required between services? Is that where client-facing service providers will emerge? What services can the market sustain? See DPC Featured project interview: Preserv, 25 July

15 Summary: policy before preservation 1.Repositories are looking for guidance on preservation 2.Repositories embrace different institutional, cultural and social constraints that will shape policy, including preservation, when they get round to defining it! 3.Proposed a hierarchical (in terms of cost) series of preservation service models so repositories can choose which one suits 4.This approach may be superseded, or supplemented, by distributed preservation services
