本文对BAC、UBC两大电子文件管理早期的研究项目进行了回顾,从研究目标、基础理论、研究方法等多方面进行了比较研究,揭示了共同的全程管理思想,解析了元数据分层和获取倾向,指出保证电子文件的完整、真实、有效和软硬件无关性是两个项目元数据设计的目标,厘定“功能需求”和元数据是电子文件管理必经之途。 This paper reviews the two major research projects of electronic document management (BAC and UBC), and makes a comparative study from the aspects of research objectives, basic theories and research methods, reveals the common management thinking of the whole process, analyzes the metadata stratification and And pointed out that it is the goal of the two project metadata design to ensure that the integrity, truthfulness, validity and hardware and software independence of electronic documents are guaranteed. Determining “functional requirements” and metadata is the only way for electronic document management.
