摘要
互联网环境下信息资源共享机制研究正处于方兴未艾的阶段,网络上电子图书馆的出现从很大程度促进了图书资源的共享,但单靠一个组织或公司来收集提供电子图书共享服务,无论从图书数量还是服务能力来看,都是远远不够的。只有充分的利用互联网上众多PC上的电子图书资源和服务资源,才有可能实现电子图书资源真正意义上的全面共享。现提出一种基于层次且结构拓扑的互联网环境下电子图书共享机制来管理和组织这些分散的PC资源,使之相互协同组织其上的电子图书资源并提供电子图书发现服务。
The research on the share mechanism of information resources in interact is hot, the emergence of E-book library on the network promoted the share of book resources to a very great degree. But only depending on an organization or company to collect E-book resources and provide share service, both E-book amount and service ability are lack. Only making sufficient use of tremendous E-book and service resources on numerous PCs in internet, it is just probable to carry out the overall share of E-book resources. This paper puts forward the share mechanism of information resources based on layer and structure topology in internet, which can manage and organize the decentralized PC resources, resources and to provide the e-book discovery service.
