Abstract. Recently, existing design methodologies targeting traditional Web applications have been extended for Rich Internet Application modeling support. These extended methodologies currently cover the traditionally well-established design concerns, i.e. data and navigation design, and provide additional focus on user interaction and presentation capabilities. However, there is still a lack of design support for more advanced functionality that now is typically offered in state-of-the-art Web applications. One yet unsupported design concern is the personalization of content and presentation to the specific user and his/her context, making use of the extra presentational possibilities offered by RIAs. This article addresses this concern and presents an extension of the RIA design approach OOH4RIA, to include presentation personalization support. We show how to extend the RIA development process to model the required personalization at the correct level of abstraction, and how these specifications can be realized using present RIA technology. 1.

Abstract. We characterize the “social Web ” and argue for several features that are desirable for users of socially oriented web applications. We describe the architec-ture of Deme, a web content management system (WCMS) and extensible frame-work, and show how it implements these desired features. We then compare Deme on our desiderata with other web technologies: traditional HTML, previous open source WCMSs (illustrated by Drupal), commercial Web 2.0 applications, and open-source, object-oriented web application frameworks. The analysis suggests that a WCMS can be well suited to building social websites if it makes more of the features of object-oriented programming, such as polymorphism, and class inheri-tance, available to nonprogrammers in an accessible vocabulary.
