Resumen
This paper presents the development of the Alvar Architecture, which aims to manage learning materials (images, videos, and others medias) shared by professors and the health care team from the emergency unit of a University Hospital. The main objective was to model a web-based architecture for knowledge sharing, which enables precise documents search in weak-connectivity conditions from mobile computing devices. To demonstrate and validate the architecture, a prototype was implemented, named Alvar System, using free and open source software. Early results suggest that the implemented prototype can be successfully applied in the emergency unit to promote knowledge sharing by expert professors and their students.
