提出一个自动过时风险管理系统———AOMS,可有效利用现有工具和服务解决数字资源长期保存过时问题。AOMS对长期保存中的文件格式和版本、存储媒体、硬件、软件、操作系统等进行监测,并提供风险排序和解决方法建议等功能。通过设计AOMS的框架模型和功能模块,期望能帮助数字资源管理者监控与数字资源对象有关的各种过时状况。 AOMS, an automated outdated risk management system, is proposed to effectively leverage existing tools and services to address the long-term preservation of obsolescence of digital resources. AOMS monitors long-term preservation of file formats and versions, storage media, hardware, software, operating systems, etc., and provides risk ranking and resolution advice. By designing framework models and functional modules for AOMS, we expect to help digital resource managers monitor the outdated conditions associated with digital resource objects.
