摘要
针对日益迫切的信息交换与信息共享的需求,在元计算的基础上,研究并提出了一套基于统一信息交换模型的信息交换系统,并对其组成结构、工作机制等方面进行了阐述。着重介绍了信息的统一表示、统一元信息模型及统一信息交换模型的原理及实现技术;并对该类信息交换系统的应用及其前景等作了一定的分析。
Be dead against the increasingly requirement of information exchange and shared,a informaiton exchange system based on unified information exchange model is put forward on the basis of meta-computing,and a thorough research is respectively carried out on it.The paper expounds this system's structure and its work mechanism,Describes the principle and realization technology of unified presentation of information,unified model of meta-information and unified mode of information exchange;analyzes the application of this type of system,the perspective of its application at a certain extent.
