One of the key features in MDA is model mapping, i.e., transformation of models. The source and target models of a mapping could be expressed in the same formalism (endogenous mapping) or in two different formalisms (exogenous mapping). In this paper we give some general considerations about these two kinds of mapping and we argue that the MOF operations(More)
In this paper we propose a general model of Model Mapping, one of the key features in MDA. We recall the fundamental relationships between system, model, and formalism. Then mapping of models described in the same formalism (direct) or in different formalisms (indirect) is discussed. As an example, a Constraint Checker (CC) is presented. This application(More)
RESUME. Aider un utilisateur dans ses activités médiées par un environnement infor-matique pose des questions liées à la complexité potentielle du couplage utilisateur-environnement. Une combinatoire de situations imprévisibles rend toute tentative d'aide prescriptive très difficile et le terme faciliter sera préféré au terme assister. Ce sont les traces(More)
Evaluation of automatic indexing is a common practice. Whenever new algorithms are created to generate semantic structures, it is necessary for their designers to demonstrate how better they are in the particular context for which they have been developed. However, the evaluation depends on the availability of a result of reference. Should such a reference(More)
Le système Porphyry s'appuie sur un nouveau modèle pour les bibliothèques numériques, dans lequel des experts peuvent exprimer et représenter des structures sémantiques reliant des documents. Notre contribution à ce travail consiste à y ajouter la possibilité de confronter les points de vue de ces experts, par le biais du système Platon, qui sera à terme(More)
