数字资源长期保存是通过对数字信息生命周期的管理,实现对数字对象的长期可生存能力、可呈现能力和可理解能力的维护,迁移技术已被认为是一种有效的长期保存策略。但由于其涉及诸多方面,除迁移策略选择、迁移实施、迁移途径设计等技术性问题外,还涉及到很多非技术性问题,如费用问题、版权问题、安全性等问题,目前尚无大规模的实施案例。本文在介绍数字资源长期保存迁移概念的基础上,通过对迁移过程的风险和图书馆数字迁移对象模型进行分析,进而提出数字对象迁移模型和迁移流程。最后,对目前主流迁移工具进行分析。相信对于“图书馆数字资源长期保存迁移技术分析”的研究,将对数字图书馆长期保存系统的建设起到抛砖引玉的作用。 Long-term preservation of digital resources is through the life cycle of digital information management, digital objects to achieve the long-term viability, rendering ability and understandable ability to maintain, migration technology has been considered as an effective long-term preservation strategy. However, due to its many aspects, there are many non-technical issues, such as cost issues, copyright issues, security issues and so on, in addition to the technical problems of migration strategy selection, relocation implementation and migration path design, there is no large-scale implementation Case. Based on the introduction of the concept of long-term preservation and transfer of digital resources, this paper analyzes the risk of migration process and the object model of digital library migration, and then proposes the migration model and migration process of digital objects. Finally, analyze the current mainstream migration tools. Believe that “library digital resources long-term preservation and migration technology analysis ” research, digital library long-term preservation system will play a pioneering role.
