An Analysis of Major OAIS-based Digital Preservation Systems
基于OAIS的主要数字保存系统研究*

The paper analyzes several systems and selects six of them which are more compatible to the OAIS model and have common characteristics of digital preservation systems. We discuss in details about the origin and implementation of these systems, and also investigate the technical methods and consideration on system design and implementation, especially the ones that instantiate the OAIS model. We summarize the common and regular characteristics in system design and implementation, and provide useful references for future development.
