A Catalogue of Refactorings for Navigation Models

The evolution of web applications (from read-only applications for browsing the data to full-fledged content-modification applications) has increased the complexity of navigation models describing the set of web pages included in a web application. In this paper, we propose adopting the refactoring technique to reorganize and improve the quality of such models. This technique was initially proposed to improve the structure of source code without changing its external observable behaviour. We adapt the refactoring technique to the navigation models context and present a catalogue of refactorings specific for this particular kind of models.
