引入OAIS参考模型、ISO 16363可信赖仓储认证标准、DCC生命周期模型,比较分析长期保存主要成本模型覆盖上述标准所包含活动的范围程度,并结合成本模型的自身特征,说明呈现该覆盖程度的原因。分析表明:成本模型与3个长期保存标准有较好的兼容性,长期保存成本模型研究与实践已有较大发展,然而这些模型还不具备很好的实用性,在很多方面还有待完善和改进。 Introducing OAIS reference model, ISO 16363 trustworthy warehousing certification standard and DCC life cycle model, comparative analysis of the long-term preservation of major cost model covering the extent of the scope of activities covered by the above criteria, combined with the cost model of its own characteristics, explain the reasons for the extent of the coverage . The analysis shows that the cost model has good compatibility with the three long-term preservation standards, and the research and practice of the long-term preservation cost model have been greatly developed. However, these models are not yet very practical and have yet to be improved in many aspects. Improve.
