“…Data grids provide several functions required by DP systems, particularly when massive amounts of data must be preserved [5], offering a distributed infrastructure and services that support applications dealing with massive data collections stored in heterogeneous distributed resources. Focusing on the technical aspects first, grids are built using middleware making fundamental aspects such as file management, user management and networking protocols completely transparent.…”

“…Digital preservation (DP) combines policies, strategies and actions to ensure that digital objects remain authentic and accessible to users and systems over a long period of time, regardless the challenges of component and management failures, natural disasters or attacks [5]. This includes the preservation of materials resulting from digital reformatting, but particularly of information that is born-digital and has no analogue counterpart.…”

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. We describe a middleware system that enables a flexible choice between a grid and a 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. We 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.

Abstract-Digital preservation deals with the problem of retaining the meaning of digital information over time to ensure its accessibility. The process often involves a workflow which transforms the digital objects. The workflow defines document pipelines containing transformations and validation checkpoints, either to facilitate migration for persistent archival or to extract metadata. The transformations, nevertheless, are computationally expensive, and therefore digital preservation can be out of reach for an organization whose core operation is not in data conservation. The operations described the document workflow, however, do not frequently reoccur. This paper combines an implementation-independent workflow designer with cloud computing to support small institution in their ad-hoc peak computing needs that stem from their efforts in digital preservation.

Abstract. Digital preservation is the ability to retrieve, access, and use digital objects through time, while ensuring the authenticity and integrity properties of these objects. Data grids represent a model of storage systems designed for data management and sharing, which concept also has been proposed for digital preservation. However, since data grids are not specifically designed for this purpose, they present weaknesses that have to be handled. This poster will present a set of services to address a problem in the metadata catalogue of the iRODS data grid, strengthening that platform for digital preservation purposes.
