Abstract:


Significant progress has been made in clarifying the decision
factors to consider when choosing preservation actions
and the directives governing their deployment. The Planets
preservation planning approach and the tool Plato have received
considerable takeup and produce a growing body of
knowledge on preservation decisions. However, experience
sharing is currently complicated by the inherent lack of semantics
in criteria specification and a lack of tool support.
Furthermore, the impact of decision criteria and criteria sets
on the overall planning decision is often hard to judge, and
it is unclear what effect a change in the objective evidence
underlying an evaluation would have on the final decisions.
This article presents a quantitative approach and tool to
support the systematic assessment of criteria and their impact
in preservation planning. We discuss the reconciliation
of different quality models and present an analysis tool integrated
with the planning tool Plato. We further apply our
analysis method to a body of real-world case study material
and discuss the results. The outcomes provide directions to
optimise and automate decision-making, watch, and policy
definitions at large scales, and to lower entry barriers by
focussing on those aspects that have the strongest impact.
