Efficient description and cache performance in Aspect-Oriented user interface design

Increasing demands on web user interface (UI) usability, adaptability, and dynamic behavior drives ever growing development and maintenance complexity. Conventional design approaches scale poorly with such rising complexity, resulting in rapidly increasing costs. Much of the complexity centers around data presentation and processing. Recent work greatly reduces such data complexity through the application of Aspect-Oriented UI (AOUI) design, which separates various UI concerns; however, rendering in conventional and even AOUI approaches fails to maintain this separation, often resulting in high repetitions of concern fragments due to tangling. Even worse, mixing of dynamic and immutable components greatly limits caching efficacy as each have differing lifetimes. We extend AOUI design to push down concern separation to rendering, which reduces description size, through repetition reduction, and enables separate caching of individual concerns. Our results show considerable size reduction of UI descriptions for data presentations, faster load times and extended caching capabilities.
