Abstract

SGML is a key standard for the publishing industry. However, tools being able to deal with SGML documents, for instance editors or document management systems, still are not a great many. This paper describes the design and prototypical implementation of an abstract SGML interface in Smalltalk which is dedicated to be used for the development of SGML-aware applications. Motivation and background for the work presented here are given. The structure of SGML is analyzed and the corresponding Smalltalk class hierarchy is derived. Two example applications demonstrate the usability and power of the interface.
