Hypertext aspects of the Grif structured editor : design and applications

Overview & Synopsis

This report presents the experience gained in developing and using the hypertext functionalities of the Grif system. Grif is a structured document editor based on the generic structure concept : each document is represented in the system by its logical structure which is an instance of a generic structure. This notion of logical sqtructure encompasses both hierarchical structures (as is usal in structured documents) and non-hierarchical links (as is usual in hypertexts). The document model on which Grif is based is presented, focusing on the different types of links. Various applications using these links are also described. It is shown that the approaches of electronic documents and hypertext, which are often opposed to each other, can be combined for building more powerful integrated systems.
