This book constitutes the thoroughly refereed post-proceedings of the 6th International Workshop on Open Hypermedia Systems, OHS-6, and the 2nd International Workshop on Structural Computing, SC-2, held at the 11th ACM Conference on Hypertext and Hypermedia in San Antonio, Texas, USA in May/June 2000. The 19 revised full papers presented were carefully reviewed and selected for inclusion in the book. All current issues on open hypertext systems and structural computing are addressed.

This book presents the joint post-proceedings of three International Workshops held as part of the 12th ACM Conference on Hypertext and Hypermedia in Aarhus, Denmark in August 2001.The 28 revised full papers presented were carefully refereed and selected during two rounds of reviewing and revision. In accordance with the workshop topics, the papers are organized in sections on open hypermedia systems, structural computing, and adaptive hypermedia.

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. 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 hypermedia system processing and data structures, reflect results from decades of hypermedia research, including the popular Dexter hypertext reference model and the authors own extended object-oriented version of the Dexter model. One important principle is the notion of links as first-class objects outside the data. Emerging systems such as HyperWave, Microcosm, and Devise Hypermedia apply this principle to extend the capabilities of the Web. The authors also discuss the management of incomplete and dangling links, time-based media including video and sound, support for collaboration and shared hypermedia structures, worldwide distribution, and integration of third-party applications in open hypermedia systems.

This volume contains the final proceedings of the 2004 Metainformatics Symposium (MIS 2004). The event was held during 15–18 September 2004 in Salzburg, Austria at Salzburg Research.
