Abstract:
Digital preservation aims at maintaining digital objects accessible
over long periods of time, ensuring the authenticity and integrity
of these digital objects. In this paper, we propose three different
approaches to address the digital preservation problem. First, we
survey the main requirements specific to the preservation arena.
Next, we show how digital preservation can be approached as a
specific case of System of Systems Engineering. Then, we
introduce Enterprise Architecture as a framework which is
regularly used to assist information systems design and
maintenance, but can also be applied to System of Systems and
consequently to digital preservation. Finally, in such complex
environments, Risk Management is a key factor to assure the
normal behavior of systems along time. Thus, we propose a Risk
Management based approach to design and assess digital
preservation environments, enclosing the definition of context and
requirements, and the identification of threats and vulnerabilities,
to be used as the basis of the definition of actions to deal with the
risks associated with those threats and vulnerabilities. We
generalize and survey the threats, vulnerabilities and techniques
that can be applied in the scope of digital preservation.
