Software compatibility and the law.
August 1, 1995... Despite Borland's successful appeal in the Lotus case and other legal decisions affirming the right of competitors to achieve compatibility with an existing program as a matter of copyright law, the legal struggle over software compatibility...

Target: Internet.
August 1, 1995... Cairo, Egypt - During United Nation's 9th Congress on Crime, I tussled, verbally, with the Chief of Police for Saudi Arabia. The match ended in a draw. As a featured speaker to the U.N., I made the case for full and unrestricted access to the...

Designing hypermedia applications. (includes related article)(Cover Story)
August 1, 1995... The world has glimpsed a subset of hypermedia functionality and its potential for structuring and accessing information through the recent surge in World-Wide Web (WWW) activity. Yet, we lack guidelines and tools to design and develop hypermedia...

Toward augmenting the human intellect and boosting our collective IQ.(Designing Hypermedia Applications)
August 1, 1995... It is a pleasure to play opposite Ted Nelson; much different from waving to each other across the wide, very sparsely populated frontier spaces of old. How did I wander into that frontier? I became motivated (committed) in 1951 to improving...

The heart of connection: hypermedia unified by transclusion.(Designing Hypermedia Applications)
August 1, 1995... I can imagine few honors greater than a facing page to Douglas Engelbart's; he is one of the great men of our century and I love him dearly. Like Doug I have had a unified vision, of which today's popular attainments are only centerless shadows...

RMM: a methodology for structured hypermedia design. (Relationship Management Methodology)(Designing Hypermedia Applications)
August 1, 1995... Hypermedia development, especially on a commercial scale, often involves teams of developers who need to be managed and coordinated over an extended period of time. Formal systems development and project management techniques are needed to ensure...

The object-oriented hypermedia design model.(Designing Hypermedia Applications)
August 1, 1995... Hypermedia applications typically include complex information, and may allow sophisticated navigation behavior. The Object-Oriented Hypermedia Design Method (OOHDM) [4] uses abstraction and composition mechanisms in an object-oriented framework...

A systematic approach to designing a WWW application. (World Wide Web)(Designing Hypermedia Applications)
August 1, 1995... In this sidebar, we demonstrate the systematic design principles and methodologies advocated by many of this special section's authors for a World-Wide Web (WWW) application. We used these approaches to reimplement ACM SIGLINK's LINKBase,...

Hypertext design environments and the hypertext design process. (includes related article)(Designing Hypermedia Applications)
August 1, 1995... Improving the quality of hypermedia design and reducing its cost is an important challenge for the information industry. One way to tackle the problem is to provide hypertext designers with appropriate development environments. Hypertext...

Hypermedia and cognition: designing for comprehension.(Designing Hypermedia Applications)
August 1, 1995... From the beginning, hypermedia application design has been driven primarily by technological innovations and constrained by technical feasibility. For the last few years, however, usability methods and results from human factors research have...

Visual clues for local and global coherence in the WWW. (World Wide Web)(Designing Hypermedia Applications)
August 1, 1995... The user of a hypermedia publication needs to be supported in two interrelated tasks: local and global navigation. Local navigation involves following hypertext connections between pairs of specific nodes. Global navigation involves movements...

Designing hypermedia: a collaborative activity.(Designing Hypermedia Applications)
August 1, 1995... While approaches exist for designing hypermedia applications with respect to content, structure, and presentation [2], little attention has been paid to the actual process that individual designers incur (see Nanard and Nanard in this issue) or...

The StudySpace Project: collaborative hypermedia in nomadic computing environments.(Designing Hypermedia Applications)
August 1, 1995... The StudySpace Project at Washington University School of Medicine is bringing together an assortment of computing and communications technologies to address the challenges of health sciences education. Collaborative hypermedia is the key...

Hypermedia design analysis, and evaluation issues.(Designing Hypermedia Applications)
August 1, 1995... One can perform a heuristic evaluation of a hypermedia application effectively by coupling a systematic analysis of the application based on a hypermedia design model with general usability criteria, independent of the specific application area,...

Spatial hypertext: designing for change.(Designing Hypermedia Applications)
August 1, 1995... Hypertext,(1) in its most general sense, allows content to appear in different contexts. The immediate setting in which readers encounter a specific segment of material then changes from reading to reading or from reader to reader. Authors...

On the design of hyper "spaces."(Designing Hypermedia Applications)
August 1, 1995... The hypertext author is an architect designing new conceptual spaces which should be as easy to navigate as possible. It is often useful to support navigation by structuring the information space with an explicit spatial metaphor. Many hypertext...

Designing hypertext support for computational applications.(Designing Hypermedia Applications)
August 1, 1995... Many scientific and business applications are computational, as opposed to display-oriented. Examples include accounting applications, computer-aided design systems, geographic information systems, expert systems, and statistical analysis...

To embed or not to embed....(Designing Hypermedia Applications)
August 1, 1995... Hypermedia systems may be classified by how they store both links, and the information indicating their destination nodes and which areas within a node's content are "hotspots" or buttons. There are three approaches to storing this information:...

Hyperform: rapid prototyping of hypermedia services.(Designing Hypermedia Applications)
August 1, 1995... An essential task in designing and developing hypermedia applications is to provide the necessary underlying hypermedia services (see Bieber and Kacmar in this issue). Hypermedia applications basically can be constructed in two distinct ways: by...

Dynamic hyperdocuments: authoring replaces programming.(Designing Hypermedia Applications)
August 1, 1995... The Trellis project has produced a unique algorithmic view of hypertext. Links give structure both to the dynamic activity of browsing and to the information being browsed. The dynamics of browsing may involve several users, acting in concert or...
