Abstract
We propose a precise UML-based authoring method for Web applications. This authoring method is part of the UML-based Web Engineering (UWE) approach. Starting with a requirement analysis done by use cases technique, it focuses on the design phase. The conceptual model of the application is used as guideline for modeling the navigation space. From the navigation space model we derive, in a next step, a navigation structure model which shows how to navigate through the navigation space using access elements like indexes, guided tours, queries and menus. Finally, a presentation model is constructed based on the navigation structure model. It provides an appropriate UML notation to support sketching and storyboarding. In addition, we suggest to use UML interaction diagrams to represent the presentation flow. During the whole development process we identify steps that can be performed in an automatic way thus providing the basis for a generation mechanism for Web application design. The different models of the design process are represented by using a UML conform extension of UML for Web applications (UML profile). The authoring process is illustrated with an example: a Web--based conference review system. The strength of the presented Web engineering approach is given by the fact that we use exclusively the UML notation and techniques. Moreover, our specification of constraints with OCL (part of UML) allows augmenting the exactitude of the models. In the same way our methodology has a high degree of precision in the description of guidelines of the authoring process of Web application, which can even partially be automated.
