Abstract

Modern hypertext applications require new system support for hypertext authoring and user navigation through large sets of documents connected by links. This system support must be based on advanced, typed data models for describing the information structure in different application domains. Schema based structuring through strongly typed documents and links has already been proposed and put to practical use in a multitude of hypertext applications. Systems such as Multicard/O2 and MORE have moreover exploited conceptual schemas for querying the resulting hyperdocuments in a more structured way. Shows how hypertext schemas and query languages can be utilized for designing hypertext authoring and browsing environments for large hypertexts. Illustrates mechanisms using the Gram data model and describes their implementation on top of the Multicard hypermedia system connected to the O2 object oriented database management system
