摘要It is a trend that SOA is becoming the future enterprise software architecture world widely.The key point is howto describe and discover services,thus these mainly rely on UDDI.Firstly,the current situation of SOA and UDDI are introduced,and then UDDI V3and related technical specifications are analyzed.Secondly,UDDI models,working principle,the mapping of WSDL and UDDI,and its implementation technologies are delved into.On this basis,the overall framework of UDDI is built and the service publishing and inquiring process are analyzed.Finally,a registry based on the latest standard of UDDI is achieved.
摘要Service and information resources are two kinds of major shared resources in virtual enterprises, where, service resources include third party’s service resources and enterprise’s legacy service resources,and information resources include database resources and file resources. Since service and information resources have distributed, autonomic, remotely bound as well as some other similar characteristics, an implementation mechanism on managing shared resources based on UDDI are presented. XML instances are used to describe resources authorization information, WSDL based special XML instance represents information resource metadata, and these XML instances are referenced by tModel for realizing the purpose of managing shared resources metadata based on UDDI.
摘要随着Web的迅猛发展,为了实现Web服务给应用开发者和服务使用者所带来的益处,必须要有一个合适的服务发现机制来支持Web服务,UDDI(Universal Description Discovery and Integra-tion)技术是解决这一问题的方案之一。本文对基于UDDI的语义Web服务匹配算法进行了研究,将语义Web和Web服务发现相结合,提出了一种基于语义的Web服务发现匹配算法,该算法采用多层过滤的思想,较好地实现了服务与请求间的快速匹配。
