Adaptive hypertext design environments: putting principles into practice

This paper discusses the design of a tool for authoring adaptive hypertext. First we describe the task of adaptive hypertext design. The network editing task as well as the testing phase are explored showing the importance of a design environment for authors and developers of hypertext adaptive systems. Then the required support such environment has to provide are presented. Finally we describe how principles can be translated into practice by illustrating the implementation of a design environment for developing and testing a very flexible adaptive hypertext
