Practical applitudes: case studies of applications of the ZigZag hypermedia system

ZigZag is a paradigm of hypermedia that consists of a multidimensional system of principled interconnections. Its basic features and specifications are now well known, but despite this, very few practical applications have been described or discussed. This paper examines two projects as case studies. These projects both use the unique properties of ZigZag in order to solve real-world problems. One of these case studies is a personal information management system for mobile phones, and the other is a bioinformatics visualization system. Although superficially extremely different, these areas both make use of information that is loosely structured and deeply interconnected.
