数字资源长期保存的来源感知技术研究

The Research Of Provenance-Aware Technology In Long-Term Preservation of Educational Resources

我国的数字资源建设已经进入快速发展期，提出了长期保存与使用优质数字资源的需求。分析了来源的概念内涵和数字资源长期保存应用中来源信息的重要意义。基于OAIS模型，完善了数字资源长期保存应用中的来源信息，设计了来源感知文件系统和来源收集引擎，并给出了来源收集与应用的简单示例，展望了下一步的研究目标。

The development of Modern Technology has greatly promoted the process of the ditital resources. A need of making full use of digital resources is presented. This paper discusses the connotation of Provenance and analysis the necessity of using provenance in Long-Term Preservation of digital resource. Based-on the model of OAIS， this paper designs the model of provenance for Long-Term Preservation of digital resource and presents File Systme of Provenance——Aware and the engine for collecting provenance. Finally， the thesis gives the final test result of provenance collecting and applying，it also prospect for provenance.
