Title
Canto: a hypertext data model
Source
Electronic publishing. 6(1993) no.2, S.93-113
Year
1993
Abstract
The Canto hypertext data model is chracterized by a hierarchical scheme mechanism that allows a predetermined, open-ended scheme to be embedded in the hyperdocument. Canto uses 2 types of nodes: concept nodes, which provide organizational structure, and information nodes, which contain text and other data. Describes the model, explains how it reduces user disorientation and discuss the most important features. Presents a formal specification of Canto's functionally and discusses the scheme definition language that a hypertext system designer uses to establish a hypertext scheme. Presents the scheme manipulation language which allows for alterations to the scheme and data. Describes a test conducted to determine the usability of hypertext systems built using Canto and discusses related work
