Web Service Integration Based on Abstract Forms in XML for End-user Initiative Development

Abstract — The number of end-users using the Internet has been increasing. End-user initiative development of applications has become important for automation of end-users ’ own tasks. In particular, Web applications should be supported by domain experts themselves since Web applications must be modified frequently based on domain experts ’ ideas. This paper describes end-user initiative application forms are considered as interfaces of services based on the simple concept that “one service = one form. ” Therefore, Web service integration can be defined as form transformation from input forms into output forms. There are two problems for development of Web applications by Web service integration. One is how to communicate with conventional Web applications. The other is how to merge XMLbased Web services. This paper proposes the Web page wrapping method by the HTML-to-XML transformation and the XML merging methods. In these methods, application-specific processes are described in XSLT stylesheets with visual tools by end-users, and application-independent processes are generated automatically. In particular, the multistage XML merger is introduced for treating complicated business logic
