Digital Library Thoughts: Notes from Sun Pasig

Planets - Adam Farquhar

Planets are establishing a not-for-profit organisation to ensure the long-term sustainability of Planets framework

Built a private cloud infrastructure for the entire university that hosts standard services (e.g. e-mail, eLearning portal) and Digital Library/Archive functions

National Library of New Zealand - Kevin de Vorsey

Use criterion of ability to render or migrate a file (formats can hide a multitude of sins e.g. container formats like MPEG 4) to determine the level of risk
[opinion] Perhaps adoption of file-formats and tools should be a criterion? If a file format is popular then there is a much greater chance of it being preservable.

Family Search - Gary Wright

Ingest and publish 2.75million images per week (~30TB)
Volunteer-based programme to index images. 100,000 volunteers indexing 1million names per day
Want to double ingest rate by 2010
Low quality access copy on disk (90% compression)
Archive high quality JP2K on tape (50% compressionn over tiff)
Simplify rights management - only staff user roles can access archive. Rights management is asserted at search stage so users only see what they can access.
Goal to validate each tape at least once a year but not doing it yet
Refresh of on-line storage is a looming problem

USC Shoah Foundation Architecture

Preserve visual testimony of holocaust survivors
52,000 interviews, 105,000 hours
Adding Rwanda genocide testimony
235,000 video tapes to be digitised
indexed manually in 1 min segments (people, places events). Indexing takes 2 hours per hour of video at a cost of $25million
Store low quality access copy on disk. Volume is 135TB
Store high quality archival copy on tape. Capacity of library is 8PB
Replace tapes every 3 years
All objects are signed and checked at every stage in the process. Biggest problem is network cards flipping bits during transfer!
Use physical transfer to bring back video from Rwanda, in chunks of ~140TB
