Gateways for digital preservation
![Page 3: Gateways](https://reader037.vdocuments.us/reader037/viewer/2022110210/56812abe550346895d8e84fd/html5/thumbnails/3.jpg)
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

Construction phase

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

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 active and open early in digital ‘life cycle’
![Page 7: Gateways](https://reader037.vdocuments.us/reader037/viewer/2022110210/56812abe550346895d8e84fd/html5/thumbnails/7.jpg)
What to preserve
• 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 selectiveInternet archive - whole domain
• UNESCO Guidelines• Decision Tree DPC Handbook

What to preserve
• Example – decades old remote sensing data
Australian Government
Geoscience Australia
Australia’s Remotely Sensed Data Archive:
The Next 25 Years
Stuart BarrGeospatial and Earth Monitoring Division

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
![Page 11: Gateways](https://reader037.vdocuments.us/reader037/viewer/2022110210/56812abe550346895d8e84fd/html5/thumbnails/11.jpg)
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
![Page 12: Gateways](https://reader037.vdocuments.us/reader037/viewer/2022110210/56812abe550346895d8e84fd/html5/thumbnails/12.jpg)
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.

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

Flexibility
• New gateways need to be flexible to adapt to future changes
![Page 15: Gateways](https://reader037.vdocuments.us/reader037/viewer/2022110210/56812abe550346895d8e84fd/html5/thumbnails/15.jpg)
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
![Page 16: Gateways](https://reader037.vdocuments.us/reader037/viewer/2022110210/56812abe550346895d8e84fd/html5/thumbnails/16.jpg)
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 policyNLA Digital Preservation Policy
commitment

Strengthening gateways - organisational
• Way of sharing expertise
• Formal agreements & collaborations - sharing costs e.g.
RLG The Internet Archive
PADI UNESCO
International Internet Preservation Consortium
• Collaborations cost & need commitment
collaboration
![Page 18: Gateways](https://reader037.vdocuments.us/reader037/viewer/2022110210/56812abe550346895d8e84fd/html5/thumbnails/18.jpg)
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
![Page 19: Gateways](https://reader037.vdocuments.us/reader037/viewer/2022110210/56812abe550346895d8e84fd/html5/thumbnails/19.jpg)
Strengthening gateways - organisational
• 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
Skills, education & training

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

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…
