Abstract
The purpose of Doug Engelbart's Open Hyperdocument System
(OHS) is to enable applications to implement sophisticated
hyperlinking functionality in an interoperable manner. In order to
achieve this, there must be a standard architecture for representing
hyperdocuments. Experience suggests that such an architecture be
based on a graph-based data model, consisting of nodes with
properties and typed links. In this paper, we briefly introduce the
OHS, and explain the advantages of a graph-based data model,
exploring the notion of a hyperdocument. Using a threaded forum
discussion as an example, we show how to represent a hyperdocument
using a graph-based data model, and how to integrate different
hyperdocuments in useful and compelling ways.
