This heterogeneity raises many challenges regarding the mechanisms used to customize and adapt the web portal in order to decide not only what information and services are delivered, but also how they are delivered. In contrast, during recent years many advanced web technologies have emerged which address different requirements. Some examples are portal frameworks and standards; social applications, which focus on information sharing and collaboration among users; rich internet applications, which provide users an interactive and lightweight Web experience; and “mashups”, which combine content from more than one web source to provide a new application or service. This paper describes these advanced web technologies, analyses the benefits of integrating them in a social security portal, and presents some specific usage scenarios for implementing such integration using different technology platforms and mechanisms, allowing us to identify various challenges to be addressed in the future.
