IS1 Digitised TIFFs do not meet storage and access requirements
| Title |
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. |
