Abstract

Digital preservation is the persistent archiving of digital assets for future access and reuse, irrespective of the underlying platform and software solutions. Existing preservation systems have a strong focus on grids, but the advent of cloud technologies offers an attractive option. The authors describe a middleware system that enables a flexible choice of cloud for ad-hoc computations that arise during the execution of a preservation workflow and also for archiving digital objects. The choice between different infrastructures remains open during the lifecycle of the archive, ensuring a smooth switch between different solutions to accommodate the changing requirements of the organization that needs its digital assets preserved. The authors also offer insights on the costs, running times, and organizational issues of cloud computing, proving that the cloud alternative is particularly attractive for smaller organizations without access to a grid or with limited IT infrastructure.

Preservation

The second question relates to what is actually meant by the term “preservation” in this context – why we need to preserve digital resources and what is involved in actually “preserving” digital resources.

Jeff Rothenberg(1995) provides one of the clearest accounts of some of the key challenges and tasks involved in preserving digital resources. The consultancy draws heavily upon his excellent article in this subsection. Digital preservation is broken down into three areas, each of which can then be further subdivided.
