电子环境下,因为电子文件极易被不留痕迹地删减,人们通常借助元数据来保证电子文件信息的原始性。元数据可以动态及时地获取流转情况,可以反映电子文件的原始状态。在电子文件管理系统中,元数据在电子文件管理工作环节进行有效全程控制,成为实施电子文件管理的技术保障和管理系统的关键。 In the electronic environment, because electronic documents can easily be deleted without any trace, people often rely on metadata to ensure the authenticity of electronic document information. Metadata can be dynamic and timely access to circulation, can reflect the original state of electronic documents. In the electronic document management system, metadata is effectively controlled throughout the electronic document management process and becomes the key to implementing the technical support and management system of electronic document management.
