This paper describes an object-oriented model for paper-based multimed
ia documents such as a textbook with embedded graphics. This model is
the first step towards building a manageable authoring system for the
Web, in which documents can be easily built, extended, truncated, reor
dered, assembled and disassembled on a component basis, and the docume
nt components can be reused. The model will also make accessible prope
rties which might be significant or important to the user, especially
in searching or classifying documents, such as the document title and
author. The model design is explained, and the class hierarchy for the
model is presented. (C) 1998 Published by Elsevier Science B.V. All r
