Structured hypermedia authoring: a simple tool for the design and implementation of structured hypermedia databases

© Springer-Verlag Berlin Heidelberg 1996. In this paper a new hypermedia model is presented that avoids a number of traditional problems of hypermedia authoring, and facilitates the maintenance of links and the re-use of information resources. The model was inspired by problems we experienced while implementing a hypermedia self study course on computer science [Olivié 1993]. It allows pre-structuring of hypertext, which is especially important for educational hypertext, and it allows the inclusion of semantic information which makes querying possible. We also describe a hypermedia authoring system that was developed with this model in mind. It can manage and export hypertext information webs for the World-Wide Web or other hypermedia systems. Examples are given of how we have used the model and the authoring system to implement a hypermedia course.status: publishe

Object-oriented hypertext design: authoring for reuse

In this paper we present a new approach for the development of hypertext information systems that avoids a number of traditional hypermedia authoring problems, and facilitates the maintenance of links and the reuse of information resources. The model is set-based, and integrates features from object-oriented software design models. This helps authors to make a comprehensive (and comprehensible) design before starting an implementation. We also briefly describe an authoring system that implements this model, and which uses an existing relational database system to store documents, links and meta-information.Book subtitle: INFORMATION SYSTEMS TRACK - ORGANIZATIONAL SYSTEMS AND TECHNOLOGYstatus: publishe

HOME: an environment for hypermedia objects

In this paper, we present HOME, a new environment for distributed hypermedia. We mainly concentrate on the server side, and provide access to World-Wide Web clients through a gateway mechanism. Data and metadata are strictly separated in the distributed HOME server. The architecture is based on a layered approach with separate layers for raw data, multimedia characteristics and hypermedia structure. We briefly present some of the implementation aspects and emphasise distinctive characteristics of HOME. We conclude with a comparison with related research and our plans for the future.status: publishe
