This paper proposes a reverse engineering approach for abstracting conceptual user-centered models from existing Web applications to re-document them at a high level of abstraction and from a user perspective.The recovered models are specified by referring to the Ubiquitous Web Application (UWA) design methodology. UWA models are able to describe the(More)
Large scale Web Applications, especially those intended to publish contents and provide information to their users, are by their nature subject to continuous and fast changes. This often means fast obsolescence of the design documentation and a lot of effort required to comprehend the application when performing maintenance and evolution tasks. This paper(More)
Despite several methodologies have been defined to support the disciplined development of Web applications, often such methodologies are not applied in the practice, mainly due to the short time-to-market and resource constraints. As a consequence, existing (i.e. legacy) Web applications often lack in design quality. This paper proposes a model-driven(More)
Object oriented (OO) implementations of design patterns (DP) may suffer of some problems due to deficiencies of (OO) languages affecting some quality attributes such as modularity, comprehensibility, maintainability and testability. Aspect oriented programming (AOP) provides powerful constructs able to better handle modularity and composition; these(More)
This paper presents a semi-automatic approach to Web applications design evolution which leverages the Ubiquitous Web Applications (UWA) design framework, a methodology and a set of models and tools for the user-centered design of multi-channels and context-aware Web applications. The approach is based on a two-step redesign process: first a semi-automatic(More)
Despite Model Driven Engineering (MDE) approaches are largely used to develop, update and evolve Web Applications (WAs), the use of these approaches for the development of process-centric WAs is still very limited. This is an important issue in the context of MDE considering that WAs are often used to support users in the execution of business processes. In(More)
Nowadays, Web Applications (WAs) are complex software systems, used by multiple users with different roles and often developed to support and manage business processes. Due to the changing nature of the supported processes, WAs need to be easily and quickly modified, to adapt and align them to the processes they support. In recent years, Model Driven(More)
Nowadays, process-centric Web Applications (WAs) are extensively used in contexts where multi-user, coordinated work is required. Recently, Model Driven Engineering (MDE) techniques have been investigated for the development of this kind of applications. However, there are still some open issues. First, a complete roundtrip engineering support is still(More)
SUMMARY This paper presents a semi-automatic approach for the recovery and evolution of the design of existing Web applications. The proposed approach, structured in two main phases, is based on the Ubiquitous Web Applications (UWA) design framework, a methodology based on a set of models and tools, for the user-centered design of multi-channels(More)
