中文摘要 | 远程教育的发展需要大量的资源,共享是解决远程教育资源问题的重要途径。由于资源数据规模巨大、形式复杂,元数据成为了必不可少的资源管理工具,资源共享的关键在于元数据的共享。传统的共享方式由于比较注重元数据功能的综合性和元数据本身的共享,使共享的效率相对较低。本文从整体的角度重新审视数据和元数据之间的关系,在此基础上逐步形成以元数据专业化为核心的共享模式,以期提高资源共享的效率。 |
英文摘要 | The development of distance education makes the abundance of resources a necessity. Sharing is an important way to solve the problem of resources in distance education. As resources grow in quantity, the structure of resources becomes increasingly complex. In order to manage the resources, metadata is introduced and used as a necessary tool to manage resources. Sharing of metadata is a key element in the sharing of resources. Because traditional sharing mode of metadata focuses on forming metadata with comprehensive functions and focuses more on the sharing of metadata itself, the efficiency of sharing is low. In this article, the relation between data and metadata is reflected from a systematic perspective. We then discussed a sharing mode based on specialized metadata, which hopefully can improve the efficiency of resource sharing. |
