构建以事件为核心的长期保存系统起源管理框架

Construction of a Provenance Management Framework for Long-term Preservation System Based on the Event-centric

[目的 /意义]研究建立长期保存系统起源管理框架,通过有效管理起源信息,确保长期保存系统所存档数据的真实可靠可用。[方法 /过程]基于数字对象保存周期进行起源事件定义,基于OAIS保存流程进行起源管理框架设计,以事件为核心进行起源管理功能模型和起源信息模型设计。[结果/结论]初步完成基于事件的保存系统起源管理框架的设计,既遵循保存领域的相关标准,同时兼顾实践需求,对长期保存系统具有很好的普适性和可行性,但其在有效性和实用性方面还有待进一步验证。

[ Purpose/significance ] This paper studies constructing a provenance management framework for longterm preservation system, to ensure the authenticity, reliabilityand usability of data objects archived in the long-term pres- ervation system by effectively managing provenance information. [ Method/process ] It makes the definition of provenance event based on the preservation lifestyle of digital objects, designs a provenance management framework according to the preservation flow of 0AIS, and accomplishes the design of the management function model and provenance information model based on the event-centric. [ Result/conclusion] The provenance management framework for long-term preservation system, which not only follows the relevant standards of long-term preservation but also takes into account the needs of practice, has a universality and feasibility for long-term preservation system, but still has a space for verification of effec- tiveness and practicability.
