Specifying Quality Requirements for the Web 2.0 Applications

To specify quality requirements for Web 2.0 applications we propose an integrated approach which considers features for contents, functionalities and services. In this work we discuss how to model internal quality, external quality and quality in use views taking into account not only the software characteristics – as those specified in the ISO 9126-1 quality modelsbut also the own features to Web applications (WebApps). Particularly, we thoroughly discuss the modeling of the content characteristic for evaluating the quality of information – so critical for the whole Web application eras. The resulting models contribute towards a multidimensional integrated approach to evaluate WebApps at different lifecycle stages, independently of Web eras.
