Popis: This paper reports the results of applying metrics to hypermedia authoring under the SHAPE (Southampton hypermedia authoring paradigm for education) research project. The aim of SHAPE is to help authors develop high quality large hypermedia applications for education. The quality characteristics considered are the reusability of information, the maintainability of applications and the authoring effort.In the hypertext field there have been a number of proposals for hypertext metrics, developed mainly in an ad-hoc fashion, contributing to the expression of measures in an ambiguous manner and limiting their use. Unfortunately, many measures proposed in the literature lack the necessary mathematical or empirical justification.The metrics proposed in this paper have been developed using the Goal-Question-Metric approach, and adhere to the representational theory of measurement. We describe the development of the metrics and the results of a quantitative empirical study which compares two different hypennedia authoring systems.
