Distributed Preservation Services: Integrating Planning and Actions

Abstract

Abstract. Digital preservation has turned into an active field of research. The most prominent approaches today are migration and emulation; especially considering migration, a range of working tools is available, each with specific strengths and weaknesses. The decision process on which actions to take to preserve a given set of digital objects for future access, i.e., preservation planning, is usually an ad-hoc procedure with little tool support and even less support for automation.This paper presents the integration of tools and services for object migration and characterization through a service oriented architecture into a planning tool called Plato, thus creating a distributed and highly automated preservation planning environment.

An Extensible Monitoring Framework for Measuring and Evaluating Tool Performance in a Service-Oriented Architecture

“…In the preservation planning environment described in [1], planning decisions are taken following a systematic workflow supported by a Web-based application which serves as the frontend to a distributed architecture of preservation services.…”

“…To support the processes involved in digital preservation, current initiatives are increasingly relying on distributed service oriented architectures to handle the core tasks in a preservation system [12,8,1]. This paper builds on the work described above and takes two specific steps further.…”

“…The corresponding distributed architecture, which supports and automates the selection process, relies on web services exposing the key components to be selected, which are discovered in corresponding registries [1].…”

Adding Quality-Awareness to Evaluate Migration Web-Services and Remote Emulation for Digital Preservation

“…To support the processes involved in digital preservation, current initiatives are increasingly relying on distributed service oriented architectures to handle the core tasks in a preservation system [8,7,3]. The core groups of services in such a digital preservation system are -the identification of object types and formats, -analysis and characterisation of digital objects, -the transformation of content to different representations, and -the validation of the authenticity of objects in different formats [2].…”

“…The architecture enables flexible integration of migration services from different sources and service providers [3]. However, emulation so far had to be carried out manually in an external environment.…”
