The Design And Implementation Of Extending UDDI In SDOWSCS

The B2B E-business based on Internet keeps on developing along with the development of Internet. However, as most of applications of E-business and Web-based business services nowadays are different in dealing with operation ways among purchaser, supplier, market and service supplier, it becomes a urgent problem on how to coupling these applications conveniently with low cost in order to actualizing interconnection of different business application systems in wide area. Web Services technology based on XML which is quickly developing now provides the best way to solve this problem. And Web Services composition is an application of Web Services which is based on Web Services technology. It can satisfy the need of user in higher level and realize some specific function.Our research focuses on this application to design and implement a Service Design Oriented Web Service Composition System based on some given field. We extend UDDI in this system from the angle of syntax and semantic in order to provide a more complete description model of Web Services for providers of Web Services. And the system provides the whole process of Web Service composition from designing with graphics to choosing the services dynamically and executing them for the userThis paper mainly focuses on design and realization of extending UDDI of this system after analyzing the whole system framework. In this paper, we introduce the structure of extending UDDI, then analyze and design the description model of Web Services in extending UDDI, including semantic-extended and domain ontology. Finally we give the detail description of realization of each part of extending UDDI.
