摘要
本文首先介绍了数字资源长期保存的两种基本策略———迁移法和仿真法,分析了它们的基本原理和优缺点,然后基于这两种方法的成本构成,比较分析了它们用于数字资源长期保存的费用。最后作者认为,从数字资源长期保存的成本效益角度看,仿真法要优于迁移法。
The following three aspects are discussed in this paper: (1) introduction to the two kinds of basic strategies used for digital resource long-term preservation ( migration and emulation) including their principle and advantages and disadvantages; (2) comparison to and analysis of their cost during digital resource long-term preservation; and (3) the author points out that emulation is better than migration from the point of cost-benefit analysis.
