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 one of the project's goals. The primary user organization in the Esprit projects EuroCoOp and EuroCODE, from which(More)
This paper discusses how to augment the WWW with a Dexter-based hypermedia service that provides anchors, links and composites as objects stored external to the Web pages. The hypermedia objects are stored in an objectoriented database that is accessible on the Web via an ordinary URL. The Dexter-based hypermedia service is based on the Devise Hypermedia(More)
This paper discusses how to augment the World Wide Web with an open hypermedia service (Webvise) that provides structures such as contexts, links, annotations, and guided tours stored in hypermedia databases external to the Web pages. This includes the ability for users collaboratively to create links from parts of HTML Web pages they do not own and support(More)
Early hypertext systems were monolithic and closed, but newer systems tend to be open, distributed, and support collaboration. While this development has resulted in increased openness and flexibility, integrating or adapting various different tools, such as content editors, viewers or even other link servers has remained a tedious task. Many developers(More)

This paper discusses the design and use of a generic composite mechanism in the object oriented DEVISE Hypermedia (DHM) development framework. The DHM development framework is based on the Dexter Hypertext Reference Model, which introduces a notion of composite to model editors with complex or multiple types of contents. The original Dexter notion of(More)
In this book Kaj Grønbæk and Randall H. Trigg present a set of principles for the design of open hypermedia systems and provide concrete implications of these principles for issues ranging from data structures to architectures and system integration, and for settings as diverse as the World Wide Web and the workplace.The principles, which cover both(More)
This paper presents a guided tour system for the WWW. It is a module for the Webvise open hypermedia system that implements the ideas of trails and guided tours, originating from the hypertext field. Webvise appears as an open hypermedia helper application to the user and stores the guided tours in an XML format called OHIF separated from the WWW documents(More)
This paper addresses the problem of organizing material in mixed digital and physical environments. It presents empirical examples of how people use collectional artefacts and organize physical material such as paper, samples, models, mock-ups, plans, etc. in the real world. Based on this material, we propose concepts for collectional actions and meta-data(More)
