Abstract: Web applications experience quite significant growth in attractiveness. They are currently developed for many purposes and by various groups of developers. Simultaneously, new technologies associated with the HTML5 specification have emerged. These technologies bring new functionalities available for web applications. Therefore, the main objective of this manuscript is to present three generic models (templates) that can be instantiated during development of web applications with particular functionalities. These models are focused on geolocation data, tracking and off-line access. Since, the models are general in nature, they are associated with various limitations and issues which are depicted in the paper. However, they represent quite promising starting point for further research activities that are outlined in the paper as well.
