Hi We are checking how we can make the FMRepositoryVisitor parametrized by an exporting context attached to a model. However the Repository only gets the model entities and not the model. This is a pity because we lack information held in the model (sourceLanguage, model versions, tags, who, what and the rest....) export: aModel withMetamodel: aMetamodel to: aStream | tower repository | tower := FMCompleteTower new. tower metaMetamodel: aMetamodel metamodel. tower metamodel: aMetamodel. tower model: (repository := (FMRepository with: aMetamodel) addAll: aModel entities). tower model exportOn: aStream What is the constraint that made that FMRepository does not get a model but just a list of entities? We could pass the context to a repository but it seems better to pass a model. What do you think? Stef and Andre -- Andre Hora
