Abstract
This paper presents a specification of Hypertext systems on several levels of abstraction, and describes translations between these different levels. The Hypertext system will be organised according to a stratified architecture, which is a generalisation of the so-called Two Level Architecture.
We describe a user interface for the Hypertext system, examine the user’s elementary operations (transactions) and present the corresponding user view on the system.
Next a conceptual schema is presented, that describes Hypertext from the perspective of the author (editor) of the information. We describe the user transactions in terms of operations on the conceptual schema.
An object oriented implementation of this Hypertext system is presented. We show how the object hierarchy is derived from the conceptual schema.
