PC-Hypertext: Development Shell The key to successful application development and systems integration was the availability and suitability of the MaxThink software. The use of this "off the shelf" software permitted rapid prototyping of the information system, allowing the development of several iterations in quick succession based on evaluations of the design parameters and on opportunities for system testing. While the capabilities of hypertext systems to create associative links between information nodes is significant, the essential value of nodal linking must be perceived as a component of a highly structured taxonomy of information. It is, in fact, the classification and organization of relationships between information nodes that is the foundation for the construction of effective hypertext systems. In building hypertext systems, the HOUDINI and MaxThink development programs are used to classify and organize the relationships between idea nodes. These development programs constitute the tools that structure the information (hierarchies and networks) within a system application. As such, they embody the fundamental means by which system users can ultimately access the knowledge contained in each specific application.
