The document concept commonly deals with data that documents contain, but rarely with (inter)actions that documents can handle. As a consequence, it is hard to specify how users can interact on documents : this is mainly done by dedicated applications from which users have to swap in order to achieve a single editing task. In this paper, we suggest the use of a model for interactive components based on three metaphors, the document, presentation and instrument. The proposed model aims at replacing the application concept by the document and interaction instrument concepts within interactive workplaces, thus resulting in a higher powerfulness / ease-of-use ratio.
