Mass digitisation projects generate millions of master images that must be stored in multiple locations to ensure their longevity. At this scale, storage costs (even in the short term) are considerable. JPEG2000 technology offers the potential to significantly reduce the size of digitised masters for a negligible loss of quality. Using the JP2 file format to store digitised masters therefore provides an attractive alternative to the conventional choice of TIFF. There are however considerable digital preservation concerns about JP2, which could put longevity of digitised collections at risk. This business activity will put in place a quality assurance process that will validate JP2 masters, mitigate preservation risks associated with their usage, and as a result enable considerable storage cost savings. By reducing initial storage costs by around 80%, resources will be freed up for the digitisation of one million additional pages.
The summary explains the context and current situation before describing the change to business processes that will be implemented. It focuses on the key elements for a business case of this kind: benefits, costs and risks. The text uses some technical language (mention of JP2 and TIFF) and this may be deemed too technical for the audience, in which case it may be better to refer to the technologies in general terms without specifically naming them.
