Modeling of Hypermedia Applications
by Radovan Cervenka
Abstract:
This paper introduces the Hypermedia Modeling Language --- HML, which constitutes a formal basis for modeling navigation/manipulation, synchronization and media channels handling functionality of applications having some hypermedia features. We present a logical application architecture framework which forms a principal basis for the HML language. It defines individual hypermedia aspects and determines their position within the application architecture. Using this framework for analysis and design process enables to separate the hypermedia functionality from the application layer, and improves transparency of the application architecture and modularity of particular components of the application. This leads to a higher degree of reuse and portability as well as to the ease of maintenance of the application in the deployment phase. For each layer of the framework, we discuss basic principles of its modeling. We concentrate on the navigation/manipulation, synchronization and media channels modeling.
