Abstract

Speculates on the future of hypertext focusing on 2 distinct types of application resulting from current investigations. The first approach presents hypertext as primarily a browsable database or hyperbase. The second approach, hyperdocument, draws its intellectual support from structured document research

Abstract

This paper suggests a standard format for creating hypermedia software. Teachers and students of literature have taken up the use of hypermedia technology enthusiastically and so we are rapidly arriving at a situation where a mushrooming of software for language and literature teaching will be faced. We will arrive much sooner at a situation where searching for an appropriate software would be as difficult as finding an appropriate article today. Technology is expected to optimise information to maximise knowledge: the confusion created by Gutenberg's invention is because duplication cannot be avoided. The suggested format is based on the major pillars of literary criticism - author centred, text centred and reader centred - and develops from the word to the work level. The findings have been demonstrated in the form of Technocriticism, a hypermedia program created on HyperCard

Abstract

Introduces a generic layered architecture for hypermedia systems with 4 major interfaces which will allow information interchange and code reusability between applications. The architecture uses the MHEG proposal to provide the desired independence between hypermedia applications' conceptual models and storage strategies for hypermedia object. Discuss design problems of the topmost layer, using as an example the nested context hypermedia model. As a distributed environment may be necessary to meet real time requirements of hypermedia applications addresses issues concerning the design of a distributed system based on the proposed architecture

Abstract

Describes a unified document model for an authoring system that focuses on the stage of drafting and revising and takes advantage of both hypertext and structured document models. Discusses the underlying structure and the surface of the document models and its key features. Describes Nelumbo, a prototype system currently being developed which integrates different types of editors that ahndle features of hypertext and structured documents. Users can use any of the tools at will, and editing with the tools affects the underlying structure consistently

Abstract

Presents a model for an electronic book (hyper-book). Hyper-books are electronic books defined on the basis of the paper book metaphor. Gives a formal definition of the hyper-book model as a dynamic system. The model was implemented in a working system, and evaluated with a group of users. The evaluation has confirmed that the adoption of the book metaphor is very effective, as it guarantees ease of using and understanding the system

Abstract

It is accepted wisdom that documents should be represented in terms of their logical structure rather than their appearance. Nevertheless most of the popular document processing systems concentrate on appearance rather than structure, mainly because most users opt for a user interface that is interactive, simple and direct. Considers issues related to fonts and other appearance attributes within hypertext documents. Presents the relevant differences between hypertext systems and document preparation systems whose end product is paper Describes schemes for representing appearance through logical structure. The scheme aims to meet the extra needs of hypertext systems, and yet still to be simple enough to attract wide usage.

Abstract

Describes Microcosm an open hypermedia system developed at the Univ. of Southampton. In Microcosm no information concerning links is held in documents; all link information is held in external linkbases which contain details about the source and destination anchors of the links. Microcosm is also composed of independent components which communicate by passing messages. As working in such an open environment reduces system response work is being carried out in to the use of Microcosm as a hypertext onto other delivery systems. As an intermediate stage HyTime based document structures which describe Microcosm hypertext, especially linkbases are currently being produced. A process which will convert a Microcosm dataset into this representation and then further translation programs to convert the representation to run on other hypermedia delivery systems is being defined

Abstract

Current hypertext systems have been widely and effectively used on relatively small data volumes. Explores the potential of database technology for aiding the implementation of hypertext systems holding very large amounts of complex data. Databases meet many requirements of the hypermedium: persistent data management, large volumes, data modelling, multi-level architecture with abstractions and views, metadata integrated with operational data, short-term transaction processing and high-level end-user languages for searching and updating data. Describes a system implementing the storage, retrieval and recall of trails through hypertext comprising textual complex objects (to illustrate the potential for the use of data bases). Discusses weaknesses in current database systems for handling the complex modelling required
