“…The Social Semantic Web, as a combination of the Social and Semantic Web, is becoming a reality with new types of applications such as semantic blogs and wikis (described by Kinsella, Passant, Breslin, Decker & Jaokar, 2009), and different approaches that facilitate the reuse of knowledge between social platforms, such as FOAF (Friend of a Friend, http://foaf-project.org) or SIOC (Semantically-Interlinked Online Communities, http://sioc-project.org/). In this context, this paper presents the application of S m 4RIA (Semantic Models for RIA, Hermida, Meliá, Montoyo & Gómez, 2011), a model-driven design methodology that allows the creation of semantic RIAs, to the design of Web 3.0 RIA applications. In this case, the development of a social network site with a semantic RIA is employed as running example in order to explain the different stages of the methodology and the benefits of the use of SW technologies.…”
