This work proposes a visual grammar-based approach to support web designers during the analysis and the design phases of complex hypermedia structures. The hypermedia is defined through a formal visual language at two abstraction levels: the hypermedia graph outer and inner structures. The model makes it possible to verify the correctness of hypermedia structures andion levels: the hypermedia g...

It is a well-known problem that developers of hypermedia applications need assistance for modeling and maintaining application-specific hypermedia structures. In the past, various hypermedia engines have been proposed to support these tasks. Until now, hypermedia engines either provided a fixed hypermedia data model and left extensions to the hypermedia application or they left the modeling of ...

Spatial hypermedia provides opportunities for expression not possible in navigational hypertext. However, static spatial hypermedia, just like static traditional hypermedia, has a single presentation for all use contexts. We are exploring the use of multiple adaptation models to alter the presentation of spatial hypertext. Differences between navigational and spatial hypertext expression requir...

The World Wide Web has become a widely available platform for learning with hypermedia. However, WWW hypermedia is often limited in both guidance and navigation support. To improve hypermedia in these aspects, we propose a spatial hypermedia browser for educational purposes. A prototype browser, named HyperMap, has been designed to integrate guided explorative browsing with external control ove...

Recently there have been many e€orts to develop hypermedia systems. Hypermedia applications can be categorized into process-oriented and content-oriented. However, it is not a trivial task to build content-oriented hypermedia in a systematic fashion. Content-oriented hypermedia systems are developed primarily for the applications of marketing or information services. This paper proposes a metho...

In this paper we present the design concepts and data modeling approach that was used to define a general application framework for storing hypermedia documents in the object-oriented database management system VODAK. We exploit the capabilities of the VODAK data model to introduce new hypermedia modeling primitives at the meta level. We show that representing the hypermedia semantics within th...

We propose a graph-based hypermedia model, where hypermedia dynamics is specified through graph transformation. This approach addresses the lack of an appropriate language for specifying transformations of hypermedia networks in known hypermedia development methodologies.

The Active HYpermedia Delivery System(AHYDS) is an hypermedia platform being developed at NACSIS (Tokyo-Japan) based on the PHASME Application-Oriented DBMS. The AHYDS is a media delivery platform to support various hypermedia applications. The features of customisability and active behavior enable to support different kinds of heterogeneous hypermedia applications. The demonstration shows the ...

Multi-Model Adaptive Spatial Hypertext. (December 2004) Luis Francisco-Revilla, B.S., Universidad Iberoamericana; M.S., Texas A&M University Chair of Advisory Committee: Dr. Frank M. Shipman, III Information delivery on the Web often relies on general purpose Web pages that require the reader to adapt to them. This limitation is addressed by approaches such as spatial hypermedia and adaptive hy...
