Support for Collaboration in Wikis using Graphical Modeling to Achieve Improvements in Information Architecture and Accessibility

Wiki is a collaborative tool for designing web communications allowing users to edit, add or revise content through a web browser. Despite of various benefits offered by the wikis use, there is no guarantee of a good structure of its content. This occurs especially by the difficulty to graphically visualize the information architecture. In this paper is proposed a Model-Driven Development (MDD) approach that supports creating graphical models of namespaces to generate wikis and facilitates the collaboration organization. Finally, the approach also aims to include accessibility features on models from official W3C guidelines such as WCAG and ATAG, allowing the wiki access by a wider range of user´s types.
