基于领域本体的分布式UDDI互联架构

Distributed Architecture of UDDI Interconnection Based on Domain Ontology

传统的UDDI工作方式存在数据同步和复制开销巨大以及无法体现UDDI本身领域特性的问题,该文通过领域本体对UDDI的传统工作机制进行扩展,提出了UDDI代理(UDDI Broker)的概念,通过UDDI代理构建分布式的UDDI互联架构,阐述了使用UDDI代理进行服务发布和服务请求的工作过程及相关问题。

The traditional architecture of UDDI becomes more and more inappropriate to industrial reality. The cost of data synchronization and replication is huge, and domain-specific attributes of UDDI are not contained. This paper expands the traditional architecture of UDDI. A component called UDDI Broker is proposed, which contributes to the new distributed UDDI architecture. Also the mechanism of service advertisement and request according to UDDI Broker is presented.
