Vers une approche centrée humain pour la définition de langages de modélisation graphiques

The increasing complexity of information systems (ubiquitous systems, open enterprises, etc.) calls for the introduction of always new modeling languages. However, the development of new domain-specific languages makes the question about their quality an important issue for the modeling of information systems. This article deals with this issue by suggesting a user-centred approach for language creation. Our proposals rely on our past work from different projects, but constitute a consistent whole, which allows us to show the approach interest and feasibility.
