A holistic approach to bit preservation

Abstract

PurposeThe purpose of this paper is to point out the importance of taking a holistic approach to bit preservation when setting out to find an optimal bit preservation solution for specific digital materials. In the last decade there has been an increasing awareness that bit preservation, which is to keep bits intact and readable, is far more complex than first anticipated, even in this narrow definition. This paper takes a more holistic approach to bit preservation, and looks at how an optimal bit preservation strategy can be found, when requirements like confidentiality, availability and costs are taken into account.Design/methodology/approachThe paper describes the various findings from previous research which have led to the holistic approach to bit preservation. This paper also includes an introduction to digital preservation with a focus on the role of bit preservation, which sets the scene for why bit preservation deserves attention in a holistic approach.FindingsThe paper presents different means to find an optimal bit preservation strategy. This consists of a model to delimit bit preservation activities, and will briefly discuss how specific material can require different bit preservation strategies as well as pointing to how such strategies can be evaluated.Research limitations/implicationsThe operational results described here are still missing work to be fully operational. However, the holistic approach is in itself an important result. Furthermore, in spite of the shortcomings, the results can assist in analysis and evaluation of bit preservation strategies.Originality/valueThis paper is an extract of the findings presented in the doctoral thesis “A holistic approach to bit preservation”. The findings are relevant for any organisation that is required to do bit preservation of its digital material.
