"Abstract Web applications, often referred to as AJAX, are increasing in number and capabilities. Application developers now routinely target the Web instead of operating systems. A core set of Web Standards – HTML, CSS, JavaScript and DOM -- form the foundation for most Web applications.
One guiding principle of the Web is that there is only one; the same Web standards and the same Web content should be usable on all Web devices. As such, Web applications are challenging for mobile devices. For example, they often demand certain screen sizes.
This paper discusses how web applications relate to other web content. The notion of "dynamicity" is introduced to measure how dynamic the content is. Finally, web applications for mobile devices are described".
