||IS1 Digitised TIFFs do not meet storage and access requirements|
|Detailed description|| A important part of digital preservation is the willingness and financial commitment of a memory institution to preserve the data for the long term. Given the time scales in question any cost saving is to be welcomed.
At the BL, as elsewhere, the cost of storing uncompressed TIFFs currently outweighs the risk of replacing these images with a (perhaps) compressed format.
As a side benefit, replacing the TIFF images with alternative representations will facilitate access to the materials - smaller files to manipulate and download and native tool support in browsers and standard OSs.
Access metrics also help to obtain the commitment of the memory institution to preserve data.
| Scalability Challenge
|| The JISC1 collection is high volume (80TB). There are no specific requirements around performance of migration+QA solutions, although it would be desirable to complete processing within weeks rather than months.

Hey would you mind stating which blog platform you're working with?
I'm planning to start my own blog in the near future but I'm having a
difficult time making a decision between BlogEngine/Wordpress/B2evolution and Drupal.
The reason I ask is because your layout seems different then most blogs and I'm looking for something
unique. P.S Apologies for getting off-topic but I had to ask!
