Abstract
The World-Wide Web is increasingly used as a means for accessing
on-line applications, although the Web was initially created to
access documents. In contrast to data-intensive Web sites, dynamic
Web applications are Web-based business applications that execute
business logic for changing the business state captured by the system.
Due to the central roles of business logic, it is important for
the dynamic Web applications to be modeled focusing not only on
the client-side presentation, but also on the server-side processing
such as the execution of business logic and page-flow control.
This paper proposes a Web Application Descriptor (WAD) for modeling
dynamic Web applications, and presents a prototype of the Web
Application Development Support Tooling (WAST), which is an
environment for developing Web applications based on the WAD model.
WAD specifies the navigational structure of Web applications,
and prescribes the behavior of Web applications in terms of logical
pages and actions used for directing the page flow.
WAD allows modeling such page navigation flow at a description level
independent of both the content view and the runtime application
framework, so that it can be exploited for the conceptual design
and execution of dynamic Web applications.
