数字保存成本模型LIFE和CDL-TCP比较与评价

Comparison and Evaluation of Digital Preservation Cost Models LIFE and CDL-TCP

[目的/意义]随着数字保存需求的增长,其成本问题愈受关注。通过分析和比较LIFE与CDL-TCP这两例具有代表性的数字保存成本模型,为我国数字保存成本研究提供参考。[方法/过程]归纳和梳理欧美数字保存成本模型的基本类型及特点,从简便易用性、广泛适用性、结果准确性3个方面共计7个维度对LIFE与CDL-TCP进行比较与评价。[结果/结论]欧美数字保存成本模型在通用性、准确度、实证研究的广度和深度、计算工具的成熟度方面还有待完善。建议我国在数字保存成本研究中调整和丰富成本归集的思路与维度,加强实证研究与计算工具的开发等。

[ Purpose/significance ] With the increasing requirements of digital preservation, attention has been shifted to how to cut costs. This paper aimed to provide some reference to the study in cost of digital preservation for related domestic archive institutions by comparing and contrasting of LIFE and CDL-TCP. [ Method/process] Based on the analysis of the types and academic characteristics of digital preservation cost models in Europe and America, this paper made a comparison between LIFE and CDL-TCP in terms of 3 aspects involving easy-using, wide-fitting and accurate-calculating and another 7 dimensions. [ Result/conclusion ] It was found that the digital preservation cost models in Europe and America should be optimized in generality, accuracy, the width and depth of empirical study, and the maturity of cost tools. Suggestions to studies in domestic digital preservation cost model were proposed with respect to the thinking of cost accumulation, empirical study, the development of cost tools and so on.
