Design issues for a Dexter-based hypermedia system. (Special Section: Hypermedia) (Technical)
February 1, 1994... This article discusses experiences and lessons learned from the design of an open hypermedia system, one that integrates applications and data not "owned" by the hypermedia. The work was conducted under the auspices of the DeVise project at the...

The Amsterdam Hypermedia Model: adding time and context to the Dexter model. (includes a related article describing an example hypermedia presentation) (Special Section: Hypermedia) (Technical)
February 1, 1994... On the surface, hypermedia is a simple and natural extension of multimedia and hypertext: multimedia provides a richness in data types that facilitates flexibility in expressing information, while hypertext provides a control structure that...

February 1, 1994... CMIFed is an authoring and presentation environment for hypermedia documents based on the AHM [18]. CMIFed uses a hierarchy structure to represent the document; this is shown in Figure B, part (a). The use of a hierarchical document structure...

Cooperative hypermedia systems: a Dexter-based architecture. (Special Section: Hypermedia) (Technical)
February 1, 1994... The hypermedia work discussed here is derived from our participation in the DeVise project at Aarhus University in Denmark. Developing tools to support cooperative design in a variety of application areas including large engineering projects is...

Viewing Dexter with open eyes. (the Dexter Hypertext Reference Model) (Special Section: Hypermedia) (Technical)
February 1, 1994... Many people think of hypermedia as a framework for organizing or structuring information. Others view hypermedia more from a behavioral or process-oriented perspective. It is not surprising, therefore, that existing models for hypermedia tend...

Navigating in hyperspace: designing a structure-based toolbox. (Technical)
February 1, 1994... As more books and other documents become available in electronic form, the use of hypertext systems is becoming more common. But as the size of hypertext databases grows, the "lost in hyperspace" problem may limit efficient and meaningful...
