Hi I have two question, thanks to help me. 1) I know that the MSE format allows to specify models for import and export with Moose. My question is that how I can import the MSE format as a model in the code not in Moose tool. I need to import different versions of Moose as an input model in my system that is based on Moose and my model is a MooseModel. I import my Moose model as the bundles like this: ^ Model5 addEntity: (SCG.Moose.PundleImporter new model: model5; addBundleNamed: 'Moose';run). 2) Is there any possibility to understand, in existed Moose architecture, what are the classes or packages in the different components. For example, what are the classes in Meta Description or in Meta Model? Do you know any work on Moose Architecture that explain the notion of entities in the components? Thanks, Azadeh
