Designing and Developing Digital Repositories Using Open Solutions A Strategy for Success
Given the increasing volume of digital content coming under the administration of libraries and information organizations, new solutions are called for to enable its management. Carl Grant considers some of these, along with strategies that are useful in the planning and development of digital collections in his white paper Delivering Digital Repositories with Open Solutions. Grant cites an estimate that puts the current digital collections management issue in clear perspective: "According to the one estimate 'humankind creates 5 exabytes of stored data — in paper, the equivalent of 500,000 new Libraries of Congress each year. More than 90 percent of those 5 exabytes were stored on a hard disk.'" The management of large scale repositories holding these materials involves meeting several criteria that Grant outlines:
According to Grant, in implementing repository technology, libraries need to address four areas of preservation and archiving that have been identified by Wheatley (2004) as essential, particularly in planning stages:
Meeting these criteria consistently can be threatened by such factors as media failure, hardware and software failure and operator error, though Grant notes that Sun StorageTek 5800 array incorporates technology to address both media and hardware failure possibilities. Grant lists several steps that he recommends institutions follow in architecting a digital repository solution:
