Authoring Hypermedia for Fluctuating Resource Availability: An analysis of the problem

A next step in our approach to authoring platform-independent hypermedia documents is to provide a document specification that enables satisfactory playback under fluctuating system resource conditions. We discuss the problem for both fluctuating network usage and variable end-user machine capabilities. The problem is placed in terms of an "information pipeline", where information is selected from a large store and assembled to deliver a presentation to the end-user. Our approach to the problem is to provide a high-level description of a hypermedia presentation and a means of determining media selection. A brief discussion of related work is given. A solution will be based on extensions of our existing hypermedia authoring tools. 1 Introduction This paper describes the problem of authoring platform-independent hypermedia presentations that can dynamically adapt to use available resources. This is a continuation of our work on creating transportable hypermedia presentations, where we s..
