数字保存的可识别性风险检测

Identity Risk Check for Digital Preservation

[目的]可识别性是指将一件数字对象与其他数字对象区分开来的特性,以实现该数字对象的发现和检索;设计并验证保存系统中数字对象的可识别性风险模型。[方法]阐释可识别性涵义,界定可识别性风险类型;从数字资源、保存活动与保存政策三个方面设计可识别性风险型元数据,建立可识别性风险检测方法;选择CNKI作为实验对象,实施可识别性风险检测实验,统计分析实验结果,制定降低或规避可识别性风险措施。[结论]实验结果表明,设计的数字保存可识别性风险模型是适用的。

[Purpose] Identity refers to the feature that distinguishes a digital object from other digital objects to realize the discovery and retrieval of the digital object.Designed and tested the model of identity risks for digital objects in digital preservation system.[Method] This paper first explained the meaning of identity and defined the risk types.Then,based on the three aspects of digital resources,preservation activities and preservation policy,designed the metadata of identify risk and established a check method of identify risk.Finally,CNKI was selected as the experimental object.Carried out the experiment of the identity risk check.Analyzed the result of the experiment.Formulated the measures to reduce or avoid the identity risk.[Conclusion] The experimental results showed that the model of identity risks for digital preservation was applicable.
