Un métamodèle des graphes conceptuels

Metamodeling addresses the issue of formally defining the vocabulary and rules sub- sequently used in modeling activities. On one hand, metamodeling is often identified as a key component in information system development. It defines in a formal way the modeling prim- itives that will be used in system analysis and design activites. On other hand, conceptual graphs are often identified as a key language in knowledge representation because they are sim- ple, expressive and closelyrelated to other familiar modelling languages such as UML or E/R. We propose in this paper a metamodel for conceptual graphs.
