  2. 1 Automation in digital preservation 3 Talk overview 2 Three case studies Findings What comes next? UK e-Science ALL HANDS meeting: 10 September 2008

  3. The Preservation Landscape “… if we do not actively pursue the preservation of digital material now, we risk having a gap in our intellectual record. … If you allow me another historical reference, we do not want to experience the digital equivalent of the destruction of the Alexandria Library. Scientific assets are just too valuable to be put at risk”. Ms. Viviane Reding, EU Commissioner on IS & Media “The digital preservation community’s inability to bring firm evidence to bear in support of its contentions about data loss, coupled with the alarmist rhetoric of terms such as digital dark ages and digital black hole, leave us exposed.” Prof. Ross Harvey,Charles Sturt University, NSW, Australia UK e-Science ALL HANDS meeting: 10 September 2008

  4. 1 Automation in digital preservation • Digital preservation • part of the information management • highly interdisciplinary • What actually ‘interoperability into the future’ means? • preservation of the bit streams • preservation of semantics • A coherent theory of preservation is still not developed • need justified in 2001 • currently CASPAR and SHAMAN projects are working in this direction UK e-Science ALL HANDS meeting: 10 September 2008

  5. Typical preservation issues… • Failure of any component of the technological chain • Hardware, software or support environment change. • Outcomes of a project which is not sustained. • Problems with the “the bits” • This could happen because of a storage device or medium failure; • or if a DNS entry is no longer resolvable. • Changes in the Knowledge Base • Loss of understanding or usability • Lost data on provenance or authenticity (requirements of trusted repositories) • Record of who did what and how did they do it • Strategies: migration, emulation, digital archaeology, … UK e-Science ALL HANDS meeting: 10 September 2008

  6. DigitalPreservationEurope: Research Roadmap (2007): 9 themes • Restoration • Conservation • Collection and Repository Management • Preservation as Risk Management • Preserving the Interpretability and Functionality of Digital Objects • Collection Cohesion and Interoperability • Automation in Preservation • Preserving the Context • Storage Technologies and Methods UK e-Science ALL HANDS meeting: 10 September 2008

  7. Functional Model: Open Archival Information System (OAIS) UK e-Science ALL HANDS meeting: 10 September 2008

  8. 2 Three case studies • Build upon project experiences of HATII at the University of Glasgow and partners • Appraisal • Metadata extraction based on genre classification • Risk assessment and audit UK e-Science ALL HANDS meeting: 10 September 2008

  9. Appraisal • Approach: developed sets of appraisal criteria; work on automation of their evaluation continues. UK e-Science ALL HANDS meeting: 10 September 2008

  10. Metadata Extraction Based on Genre Classification UK e-Science ALL HANDS meeting: 10 September 2008

  11. Risk Assessment and Audit • DRAMBORA (Digital Repository Audit Method Based on Risk Assessment) UK e-Science ALL HANDS meeting: 10 September 2008

  12. The Three Case Studies as OAIS Functional Entities UK e-Science ALL HANDS meeting: 10 September 2008

  13. SWOT observations UK e-Science ALL HANDS meeting: 10 September 2008

  14. 3 Findings • These case studies present various functions in the sense of OAIS model. • For such ‘smaller’ digital preservation solutions we need to know more on the common logic. • For bigger applications a coherent theory will be helpful. • The degree of automation differs! • Profiler • Single automated model • Hybrid model UK e-Science ALL HANDS meeting: 10 September 2008
