Use case and meta-scenarios for modelling Adaptive Web Applications

The acceptance of UML as a de facto standard for the design of object-oriented systems, together with the explosive growth of the World Wide Web has raised the need for UML extensions to model hypermedia applications running on the Internet. In this paper we propose such an extension for modeling requirements' users of Web application. It is called WA-UML (Web adaptive unified modelling language); a UML profile for adaptive Web applications (A WA). It increases the expressivity of UML while adding labels and graphic annotations to UML diagrams. This extension of UML defines a set of stereotypes and constraints, which make possible the modelling of AWA. These stereotypes and these constraints are applied in a number of diagrams represented within the same model and on the same diagram those which describe the system. In this paper we present use case diagram of WA-UML as well as its realization by their meta-scenario.
