Abstract

A transformationbased Web site can keep the contents of a Web site consistent by furnishing a single database and a set of transformation programs each generating a Web page from the database However when someone notices an error or stale content on a Web page in this style of Web site construction the Web site maintainer must access a possibly huge database to update the corresponding content In this paper we propose a new approach to Web site construction based on bidirectional transformation and report our design and implementation of a practical updating system called VuX We bring the idea of bidirectional transformation to Web site construction describing not only a forward transformation for generating Web pages from the database but also a backward transformation for reflecting modifications on the Web pages to the database By use of the bidirectional transformation language BiX we can obtain both transformations only by specifying a forward transformation Our VuX system is implemented as a Web server built upon the BiX transformation engine which can keep the content of Web sites consistent by updating Web pages in WYSIWYG style on Web browsers
