PROVIDING INFORMATION SYSTEMS WITH FULL HYPERMEDIA FUNCTIONALITY
The goal of this research is to provide hypermedia
functionality to all information systems. In this paper I
present the architecture of a system-level hypermedia
engine, designed both to manage fill hypermedia functionality
for an information system and to bind interface-oriented
âfront-end" systems with separate computation-oriented
"back-end "systems. The engine dynamically superimposes
a hypermedia representation over a back-end
application's knowledge components and processes. I
then describe a set of minimal requirements for integrating
the hypermedia engine. The more sophisticated and cooperative
the information system, the higher the level of hypermedia
support the engine will provide.Information Systems Working Papers Serie
On integrating hypermedia into decision support and other information systems
The goal of this research is to provide hypermedia functionality
to all information systems that interact with people.
Hypermedia is a concept involving access to information,
embodying the notions of context-sensitive navigation, annotation
and tailored presentation. This paper presents the architecture
of a system-level hypermedia engine, designed both to
manage full hypermedia functionality for an information system
and to bind interface-oriented front-end systems with
separate computation-oriented back-end systems. The engine
dynamically superimposes a hypermedia representation over a
back-end application's knowledge components and processes.
The hypermedia engine generates this representation using
bridge laws, which capture the internal structure of client
systems. Users access the application through its hypermedia
representation. The paper also describes a set of minimal
requirements for integrating the hypermedia engine with an
information system. These guidelines apply to all integration
efforts, not just that described here. Information systems will
require some supplementary routines for the engine to manage
hypermedia functionality for them. The more sophisticated
and cooperative the information system, the higher the
level of hypermedia support the engine will provide.Information Systems Working Papers Serie
Processing Structured Hypermedia : A Matter of Style
With the introduction of the World Wide Web in the early nineties, hypermedia has become the uniform interface to the wide variety of information sources available over the Internet. The full potential of the Web, however, can only be realized by building on the strengths of its underlying research fields. This book describes the areas of hypertext, multimedia, electronic publishing and the World Wide Web and points out fundamental similarities and differences in approaches towards the processing of information. It gives an overview of the dominant models and tools developed in these fields and describes the key interrelationships and mutual incompatibilities. In addition to a formal specification of a selection of these models, the book discusses the impact of the models described on the software architectures that have been developed for processing hypermedia documents. Two example hypermedia architectures are described in more detail: the DejaVu object-oriented hypermedia framework, developed at the VU, and CWI's Berlage environment for time-based hypermedia document transformations
Distributed multimedia systems
A distributed multimedia system (DMS) is an integrated communication, computing, and information system that enables the processing, management, delivery, and presentation of synchronized multimedia information with quality-of-service guarantees. Multimedia information may include discrete media data, such as text, data, and images, and continuous media data, such as video and audio. Such a system enhances human communications by exploiting both visual and aural senses and provides the ultimate flexibility in work and entertainment, allowing one to collaborate with remote participants, view movies on demand, access on-line digital libraries from the desktop, and so forth. In this paper, we present a technical survey of a DMS. We give an overview of distributed multimedia systems, examine the fundamental concept of digital media, identify the applications, and survey the important enabling technologies.published_or_final_versio
