综述了超媒体技术的研究进展，详细叙述了Ｄｅｘｔｅｒ超文本参考模型的基本概念、定义以及从超文本和多媒体结合发展成为超媒体的技术途径和实例。基于Ｄｅｘｔｅｒ模型的超媒体系统划分为存储层、运行层和内部成员层，它用一种类似于面向对象的系统设计思想，使用链和结合点，将超文本和多媒体有机地结合在一起，成为能够支持分布式多媒体信息制作、演播和资源共享的崭新技术手段。
This paper summarizes the research progress of hypermedia technology, describes the basic concepts and definitions of Dexter Hypertext Reference Model and the technical approaches and examples from the development of hypermedia and multimedia to the development of hypermedia. Based on the Dexter model, the hypermedia system is divided into storage layer, runtime layer and internal member layer. It uses a kind of system-oriented design idea similar to object-oriented system to combine the hypertext and multimedia organically by using chains and joining points. Able to support distributed multimedia information production, studio and resource sharing of new technologies.
