As the Internet continues to experience exponential rates of growth, attention is shifting away from mainstream network services such as electronic mail and le transfer to more interactive information services. Current network information systems, whilst extremely successful, run into problems of fragmentation, consistency, scalability, and loss of orientation. The development of second generation" network information systems such as Hyper-G can help overcome these limitations. Of particular note are Hyper-G's tightly-coupled structuring, linking, and search facilities, its projection of a seamless information space across server boundaries with respect to each of these facilities, and its support for multiple languages. The Harmony client for Hyper-G utilises two and three-dimensional visualisations of the information space and couples location feedback to search and link browsing operations, in order to reduce the likelihood of disorientation. This paper presents a comprehensive o verview of Hyper-G and Harmony.

“…The Local Map facility bottom left , provides a kind of short-range radar, generating on request dynamically a map of the link relationships of a chosen document, similar to the local map of Intermedia Haan et al 1992 . By default, two levels of incoming and outgoing hyperlinks are represented.…”

“…For example, Intermedia links are modeled with BIDIRECT directionality on all specifiers. This is because the endpoints of an Intermedia link are directionally interchangeable [6]. 4 In NoteCards, on the other hand, links have a definite source and destination [9].…”

“…First, we use dynamic references ("pointers") instead of anchor ids. 6 This means that link specifiers point directly at component anchors avoiding the need for an accessor function. Similar benefits accrue from our blockstructured type definitions.…”

Design issues for a Dexter-based hypermedia system

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 ways and underdeveloped in others. For instance, Dexter argues against dangling links, but we found several situations where permitting and supporting dangling links was advisable. In Dexter, the data objects making up a component's contents are encapsulated in the component; in practice, references to objects stored apart from the hypermedia structure should be allowed. We elaborate Dexter's notion of composite component to include composites that "contain" other components and composites with structured contents, among others. The paper also includes a critique of Dexter's notion of link directionality, proposes a distinction between marked and unmarked anchors, and discusses anchoring within a composite.
