Product configuration management is presented as a practical application for a prototype-based object model. Data model requirements for a configuration system are first introduced...
This paper describes a new approach to specifying graphical layouts of arbitrary objects, which is based on a TEXlike notation. Our simplest scheme offers specifications similar t...
