A b s t r a c t This paper 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 Dexter Hypertext Reference Model [8] was used as the basis for the design. Though our experiences were generally positive, we found the model constraining in certain(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 chapter represents a step towards the establishment of a new system development approach, called Cooperative Experimental System Development (CESD). CESD seeks to overcome a number of limitations in existing approaches: specification oriented methods usually assume that system design can be based solely on observation and detached reflection;(More)
This paper discusses issues for the design of a Dexter-based cooperative hypermedia architecture and a specific system, DeVise Hypermedia (DHM), developed from this architecture. The Dexter Hypertext Reference Model [9, 10] was used as the basis for designing the architecture. The Dexter model provides a solid foundation for designing a general hypermedia(More)
In most development projects, descriptions and prototypes are developed by system designers on their own utilizing users as suppliers of information on the use domain. In contrast, we are proposing a cooperative prototyping approach where users are involved actively and creatively in design and evaluation of early developed prototypes. This paper will(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 object-oriented database that is accessible on the Web via an ordinary URL. The Dexter-based hypermedia service is based on the Devise Hypermedia(More)
The Dexter Hypertext Reference model is well suited to modelling anchor-based hypermedia systems and static hypermedia structures. But it is less clear that Dexter is adequate for systems whose linking is based on embedded references like the World Wide Web (WWW), nor for modelling the dynamic aspects of contemporary hypermedia systems like DHM and(More)
This paper investigates how to support work and in particular cooperation in large-scale technical projects. The investigation is based on a case study of a specific Danish engineering company and it uncovers challenges to Computer Supported Cooperative Work (CSCW) in this setting. The company is responsible for management and supervision of one of the(More)
In this book Kaj Grønbaek 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 discusses how to augment the WWW 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 for(More)
