Recently, there is growing interest in Web service. A Web service is a software system, whose public interfaces and bindings are defined and described using XML. Because of the flexibility of XML, various schemas of Web services and XML resources exist. Therefore, it is essential to integrate various types of XML data. It is, however, practically infeasible to make a huge number of programs for every case. Furthermore, standardized methods for handling various schemas of XML data have not been proposed yet. This paper attempts to standardise XML-based web service integration. We propose an extended XML stream allows for XML integration. This enables flexible web service integration by having access to distributed XML resources without knowledge of each schema. Keyword X M L,Semi-structured Data,Distributed Database,XML Stream
