[EN] The study presented in this paper focuses on a navigational and user perspectives analysis of Web
applications, highlighting some of their critical points for modeling. To consider these critical points, we propose
a notational definition focused on a general metamodel, consisting of three specific metamodels: the Navigational
Tree, the Node, and Roles. The metamodels have been implemented with a specific MDA (Model Driven
Architecture) tool called AndroMDA, to generate applications for PHP language. Both, the general metamodel
and its implementation have been analyzed by means of a proof of concept. Finally, some interesting results as
well as the contribution of the proposed metamodel in comparison with other methodological proposals are
discussed.The first author would like to thank the “Itaipu Technological Park” (Parque Tecnológico Itaipú – PTI) for partially funding the research under a scholarship programGonzález, M.; Casariego, J.; Bareiro, JJ.; Cernuzzi, L.; Pastor López, O.
