| dc.description.abstract | UDDI (Universal Description Discovery & Integration), in a structured way, restores messages regarding a company and its services, and through UDDI people can publish and search the messages. However, the traditional UDDI approach -- mainly through business service entity’s identifier (keyword-base) and classification (category) to carry out enquiries -- is unable to meet users’ various searching needs. In addition, the located services were not user-friendly, which means users usually have difficulties in understanding and applying the services. Therefore, the focus of this paper is to improve the inadequate search capabilities under traditional UDDI and to provide a better mechanism for service delivery.
We add two features to enhance UDDI search capabilities. The first one is to combine the rapid rise of Web 2.0 sites which emphasizes on principle of ＂interaction, sharing and participation＂ with SOA (Service-Oriented Architecture) environment. This new environment will allow users to perform free tag classification, rating services, ranking services, and collaborative authoring services. The other one, contrast to the traditional UDDI for not providing WSDL (Web Service Description Language) based searching services, is to develop a set of WSDL filtering mechanism (WSDL Filter Services) which allows users to search services in UDDI according to the elements of WSDL document.
Finally, we introduce the extended BPEL (Business Process Execution Language) engine developed by our laboratory to our service delivering mechanism. It will enable users to apply the service with user-interface approach immediately after services are located. In other words, the improved UDDI is not only a platform for Web services searching, but also a platform for Web services using. | en_US |
