| 摘 要： | 提出一个分层数字图书馆基础架构LDLI（Layered Digital Library Infrastructure)，详细阐述和论证了LDLI理论信息对象层的设计与实现。在信息对象层，将Internet上分布式多媒体信息资源抽象为信息对象（Info-object)的概念，定义了信息对象的3个层次和各层所实现的接口。

| Abstract: | In this paper a framework of layered digital library, called layered digital library infrastructure (in short, LDLI) is introduced. The core ,of LDLI is info-object layerits design and implementation is defined here. LDLI abstracts and encapsulates multimedia information on the Internet into an information entity--info-object, the author also defines three layers of info-object and the interface of each layer. ;;; |
