摘要

The rapid advance of the Internet has brought with it a variety of WWW applications. Integration of these WWW applications, which implies development of meta level applications (shortened to meta-applications), is an important research issue. In the Internet context, XML has attracted a great deal of attention and will be used as a standard data format in WWW applications. This paper proposes a scheme to develop meta-applications on top of XML-based WWW applications. Our approach uses an XML query language called X~2QL to manipulate XML instances. X~2QL features the inclusion of user-defined foreign functions so that we can define functions specific to WWW application integration, such as submitting forms and following hyperlinks. In addition, we propose X~2PL, which is an extensible XML processing language. In X~2PL, processing flows composed of embedded X~2QL queries are specified. This paper also describes an integration example and the development of a prototype system.
