  1. Gateways Heather Brown Project Officer, State Library of S.A, for Business Information Program, University of S.A. and Assistant Director, Paper, Artlab Australia

  2. Gateways for digital preservation

  3. The challenges 'Information stored in digital form is as delicate as archaeological remains of flora and fauna... Preservation of digital information requires active intervention; left unsecured it is susceptible to loss through the physical breakdown of the media, rendered inaccessible by technological advances, or left meaningless through lack of or insufficient contextual evidence.' Seamus Ross 2000

  4. Construction phase

  5. Construction phase plans • We have to start now… • Start planning • …Use Cornell University’s • Online digital preservation tutorial www.library.cornell.edu.iris/tutorial/ • Survey of Institutional readiness

  6. Construction phase • Gateways being constructed by variety of stakeholders • Likely to be built and sustained by stakeholders with interest in or responsibility for preserving knowledge for future • Gateways need to be activeand open early in digital ‘life cycle’

  7. We cannot preserve everything Link with collection management policies Challenges - sheer volume, varying quality, new emerging genres, need to act quickly How much to select in web archiving – PANDORA selective Internet archive - whole domain UNESCO Guidelines Decision Tree DPC Handbook What to preserve

  8. Example – decades old remote sensing data What to preserve

  9. Strengthening gateways - technological • Cornell Digital Preservation model - 3 interrelated parts technological organisational resourcing refreshing migrating emulating

  10. Strengthening gateways - technologically Hybrid solutions - microfilm A low risk option for text-based content ‘Hybrid’ option: mf for long term preservation; digital copy for flexible access

  11. Strengthening gateways - technologically Standards, guidelines & trusted frameworks • The foundations – ensure quality and trustworthiness • Good progress with particular formats e.g. TIFF • ISO standards for preservation of digital materials • UNESCO Guidelines http://www.unesdoc.unesco.org/images/0013/001300/13007le.pdf OAIS model • Provides common framework for describing & comparing digital archives

  12. Strengthening gateways - technologically Preservation metadata • Underpins OAIS framework • Records info. needed to manage preservation • ….PREMIS model Unique identifiers & encapsulation • Help provide access to trusted digital objects • Also digital watermarking, digital time stamping etc.

  13. Strengthening gateways - technologically TRAC Checklist • Guide for determining trustworthiness www.crl.edu/PDF/trac.pdf • Uses risk management framework • Draws on OAIS model

  14. Flexibility • New gateways need to be flexible to adapt to future changes

  15. Strengthening gateways - resourcing • Finding ongoing funding $R is challenging • Overall volume of data will continue • to grow - the ‘digital black hole’ • Start up costs easier • Ongoing costs mean reallocation resourcing

  16. Strengthening gateways - organisational • Reflected through the policies, procedures & plans • Getting ‘buy in’ right from the top. • Without this high level commitment, • gateways will collapse • e.g. ‘elevator pitch’ • approaches of Cornell and DSpace. • e.g. of high level policy • NLA Digital Preservation Policy commitment

  17. Strengthening gateways - organisational • Way of sharing expertise • Formal agreements & collaborations - sharing costse.g. • RLG The Internet Archive • PADI UNESCO • International Internet Preservation Consortium   • Collaborations cost & need commitment collaboration

  18. Strengthening gateways - organisational • Organisational infrastructure involves … • W e need whole new skill sets • Not only technological knowledge - also generic skills that relate to organisation & resourcing • Challenge • for universities & educators of librarians to provide relevant foundation of knowledge & skills • for all to develop our knowledge & skills as part of life-long learning. Skills, education & training

  19. Strengthening gateways - organisational Skills, education & training • Formal training e.g. - Business Information • Management (BIM) Course - University of S.A. • India - DELNET, ICDL Conference on Digital libraries, • ISI’s International Workshop on digital preservation of heritage etc. • Online courses – e.g. Cornell Tutorial • PADI

  20. Conclusion • Combination of features • Still under construction  No ‘readymade’ kit •  Include the whole range of features… • For maximum leverage – collaborate with parallel gateways • Integration determines whether • gateways will remain viable organisational technological resourcing

  21. Conclusion • Right combination is a dynamic • ‘Good library management’ • Assess the preservation readiness of your organisation’s digital resources • You can no longer afford to delay…
