Nowadays, there are a growing number of Web 1.0 applications that are migrating towards Web 2.0 User Interfaces, in search of multimedia support and higher levels of interaction among other features. These Web 2.0 features can be implemented using RIA technologies. However, most of the current Web Models do not fully exploit all the potential benefits of Rich Internet Applications. Although there are interesting works that extend existing methodologies to deal with RIA features, they do not fully exploit presentation issues. RUX is a method that focuses on the enrichment of the User Interface while takes full advantage of the functionality already provided by the existing Web models. Far from explaining RUX-Method in detail, this paper focuses on the way the method deals with the definition and transformation of components at different levels of abstraction for different RIA rendering platforms.
