Life cycle management

• Next steps
• digital life cycle
• eventual aim to combine traditional and digital
  life cycles
• for decision making in responsible stewardship of
  the BLs hybrid collections
• to determine whether the calibration is right
  between the different stages in the life cycle

19
Data lifecycle management

• Digitised Masters
• L.I.F.E (Lifecycle Information for E-Literature)
• voluntary deposit e-publications
• web archiving
• e-journals
• KB taskforce on Permanent Access to the
  Scientific Records
• Outline digital life cycle issues for
• i) scientific data-sets
• ii) scientific e-journals
• iii) scientific web sites

20
TYPES OF DIGITAL MATERIAL in BL

• Wide range of different types of material, for
  example
• e-journals
• voluntary legal deposit
• digital newspapers
• digitised masters
• digital maps
• e-theses
• grey literature
• web sites
• e-literature

LIFE Lifecycle Information for e-Literature

• LIFE Lifecycle Information for e-Literature
• JISC 4/04 Projects Supporting Institutional
  Digital Preservation and Asset Management
• University College London and British Library
• i. questions
• ii. life cycle models
• iii. exemplars at UCL and the BL
• iv. conclusions and recommendations

23
LIFE Lifecycle Information for e-Literature

• What are the long term costs of preserving
  digital material?
• Who is going to do it?
• What are the long term costs for a library in
  HE/FE to partner with another institution to
  carry out long term archiving?
• What are the comparative long term costs of a
  paper and digital copy of the same publication?
• At what point will there be sufficient confidence
  in the stability and maturity of digital
  preservation to switch from paper to digital for
  publications available in parallel formats?
• What are the relative risks of digital versus
  paper archiving?

24
LIFE Lifecycle Information for e-Literature

• Life cycle models
• Harvard
• Koniklijke Bibliothek
• Lavoie centripetal centrifugal
• Design methodology
• LTAqITMAcTSTPT
• Exemplars
• voluntary deposit electronic publications
• web archiving
• e-journals

25
LIFE emerging findings

• Voluntary deposit of electronic publications
• since 2000, c.210,000 digital objects
• interim solution into Digitool
• destined for BLs Digital Object Management
  Programme - part of national digital library
• no file format is obsolete after 5 years
• estimated 2 of files need attention after 5
  years
• ingest costs double when manual
• preservation metadata needs costing
• development of migration tool required

26
LIFE - emerging findings

• Web sites
• part of UK Web Archiving Consortium
• www.webarchive.org.uk
• early indications
• acquisition rights negotiation time consuming
• ingest quality assurance time consuming
• systems in use dictate aspects of costs

27
LIFE - emerging findings

• UCL electronic journals
• early indications
• since 1997, 600 journals
• mapped to UCL and BL
• content not stored locally at UCL accessed via
  internet stored remotely by publishers
• more akin to paper serials
• whose ingest stage costs? whose storage stage
  costs? whose preservation responsibility?
