Future Access to the Scientific and Cultural Heritage – A shared Responsibility

This talk explores the challenges of preserving and accessing scientific and cultural heritage in the digital age, including the need for harmonized data, preservation strategies, and the role of representation information.

  1. Future Access to the Scientific and Cultural Heritage – A shared Responsibility Birte Christensen-Dalsgaard State and University Library

  2. Outline of talk • Staging the challenges data and their representation • The expectation of researchersbased onfield studies in Planets • Preservation focus • Planets • CASPAR • Summary

  3. Collection Description – depends on purpose for use

  4. Data – harmonised for immediate use Should we keep the original?

  5. Data – From Bits to Interpretation Level 2 GOME Satellite instrument data From CASPAR

  6. New Media • We establish collections to give future generations access to this cultural heritage – but how will they access and use it? • The answer will influence preservation strategies and quality measures

  7. Information is the important thing Information: Any type of knowledge that can be exchanged. In an exchange, it is represented by data. • What information? • Documents…… • Data……. • Original bits? • Look and feel? • Behaviour? • Performance? • Explicit/ Implicit/ Tacit Long Term is long enough to be concerned with the impacts of changing technologies, including support for new media and data formats, or with a changing user community. Long Term may extend indefinitely. Ensure that the information to be preserved is Independently Understandable to (and usable by) the Designated Community. From CASPAR

  8. Interview with three futurologists • If knowledge is not available 24/7 and accessible in a meaningful way – then it is not used • Searching on the basis of words will disappear – will start to search on the basis of argumentation • Data are stored in international databases. Databases are linked. • Data becomes cheaper to reconstruct by the minute – cheaper to reconstruct than to store.

  9. Trends – which might be explored • Researchers are not prepared to travel to collections as part of their normal research. May go before publishing • Researchers use many sources – but miss handles to evaluate quality (authenticity) • What is perceived as the best copy? • We live in a global society and researchers and citizen's act and think internationally – and work with linked or integrated material • Opening hours – meaningful? • Formulate queries in more abstract terms?

  10. How to document the creation of ideas? Output - Process

  11. CASPAR and Planets • CASPAR – focus on developing framework and methodology for capturing relevant information as part of the process • Planets – focus on creating framework and methodology for common, existing objects

  12. PreservationPlanning Services Project Architecture Reflects Problem Structure UserCommunity Preservation Action Services Test Bed:evaluation and validation services Dissemination Take-up & Training SupplierCommunity Characterisation Services Interoperability Framework From Planets

  13. Interoperability Framework • Includes • Interoperable distributed services • Service registries and shared data-stores • Encapsulate tools as services • Orchestration capability to combine services From Planets

  14. From CASPAR Representation Information • The Data Object is “interpreted using” the Representation Information (RepInfo) • The Reference Model is designed to ensure that an OAIS is not set the impossible task of having to provide all possible RepInfo immediately • Hence: • Take account of the Designated Community and its associated Knowledge Base • The amount of RepInfo is not fixed • Additional RepInfo will be needed over time How do we define a Designated Community? Created how? By whom?

  15. From CASPAR Why focus on Representation Information? • Shareable • A piece of Representation Information (RepInfo) can be associated with large numbers of different digital objects • Shared need • RepInfo Network – potentially huge and growing (as Designated Community Knowledge Base changes) • Huge variety • Structure, Semantics, Software etc But • Of course we need lots of other “metadata” • PDI, Packaging, Descriptive – Information plus…

  16. Rep • Info CASPAR information flow architecture Virtualisation How do we capture the Representation Information? From CASPAR

  17. Summary • Focus on sharing the effort involved in Digital Preservation • Forward looking: Digital Preservation should be an integrated part of information creation • Retrospective: Hard work
