Une approche fondée sur l'IDM pour le développement d'un environnement de production journalistique

This paper presents an application of Model Driven Engineering to the design of a complete news processing line within the scope of culture and leisure information. MDE is the only technology actually enabling to master the management of complex composite events with spatial and temporal properties, and to cope with making heterogeneous applications interoperate. We provide an overview of our approach and outline the salient points of our metamodels. The stress is put on the event metamodel, standing as a pivot between the beforehand Natural Language Processing, and temporal information visualization frameworks on the end user side. MOTS-CLÉS : validation sémantique, IDM, information temporelle, événement.
