Grif is a structured document editor based on the generic structure concept: each document is represented in the system by it~ logical structure which is an instance of a generic structure. This notion of logical structure encompasses both hierarchical structures (as is usual in structured documents) and non-hierarchical links (as is usual in hypertext). 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 elect ronic documents and hypertext, which are often opposed to each other, can be combined for building more powerful integrated systems.
