  1. Preservation Planning in PLANETS Lisbon Sept 6, 2007 Christoph Becker Vienna University of Technology

  2. Agenda • Preservation Planning in the PLANETS project • Decision Support for Preservation Planning • Workflow • Case Studies • Tool support

  3. Digital PreservationToday • Variety of solutions and tools exist • Each strategy has its unique strengths and weaknesses • Requirements vary across settings • Decision on which solution to adopt is very complex • Documentation and accountability is essential • Preservation planning assists in decision making

  4. PLANETS Preservation Planning • Organisational policy and strategy models • Usage models • Collection profiling • Proactive planning • Decision support for preservation planning • Tools to support and automate preservation planning

  5. Preservation Planning Methodology • Support evaluation of preservation strategies • Identify requirements for different settings • Execute experiments and evaluate outcome against well-defined requirements and needs • Well-documented decisions • Based on DELOS Testbed • Dutch Testbed • Utility Analysis • Structured model for preservation requirements

  6. Process Overview

  7. Phase 1: Define requirements • Define basis • Collection • Institutional settings • Choose sample objects/records • Representative for the objects in the collection • Define requirements • Identify requirements • Create objective tree

  8. IdentifyRequirements • Identify goals and requirements • Tree structure • Start from high-level goals andbreak down to specific criteria • Usually 4 top-level branches: • object characteristics (content, metadata…) • record characteristics (context, relations…) • process characteristics (scalability, error detection, …) • costs (per object, HW/SW, personnel, ...)

  9. IdentifyRequirements Analog… … or born-digital

  10. Assign Measurable Units • Leaf criteria should be objectively measurable • Seconds per object • Euro per object • Bits of colour depth • Subjective scales where necessary • Complexity of a file format • Error tolerance • Quantitative results

  11. Phase 2: Evaluate Alternatives • Define Alternatives • Tools and parameters • Go/No-Go decision • Develop experiment • Run experiment • Evaluate experiment • Measure performance

  12. Phase 3: Consider Results • Transform measured values to a unified scale (0-5) • Set importance factors • Analyse results • Aggregate values • Performance of each alternative • Overall • On each level • Rank alternatives

  13. Summary • Decision support for preservation planning • Evaluate alternative preservation strategies • Clearly defined and measurable criteria • Well-defined experiments • Documented and accountable decisions
