[目的/意义]探索设计并实施长期保存系统起源信息封装策略。[方法/过程]首先分析OAIS信息模型的详细组成,然后分析长期保存系统起源封装的特定服务需求,总结国际主流起源封装策略的基本特点,提出基于OAIS信息模型的起源信息封装策略,并利用Fedora仓储系统的内容模型FOXML进行封装实现。[结果/结论]该策略遵循OAIS及PREMIS标准,全面记录起源信息,具有灵活可扩展的特点,但同时管理和使用相对比较复杂。
[Purpose/significance] This article tries to design and implement a packaging strategy of provenance information for the digital preservation system.[Method/process] The author analyzed the composition of the OAIS information model in detail, then concluded the individual demand about provenance information packaging in the digital preservation system, and summarized the basic characteristics of mainstream packaging strategies. Furthermore, it puts forward a provenance information packaging strategy based on the OAIS information model and implemented it by using the FOXML format of Fedora repository.[Result/conclusion] This strategy followed the OAIS and PREMIS. The provenance information is recorded in a comprehensive way, which has the characteristics of flexibility and extensibility, but the management and usage are relatively complex.
