You can generate and customize artifacts created from the model.
Artifacts are generated using the mdmgen.xml ANT build script, which is created by the new MDM Development Project wizard and placed in the root of the project. You may customize the mdmgen.xml and mdmgen.properties files.
If you want to recover the original versions of the mdmgen.xml and mdmgen.properties, delete the files from the workspace and run code generation using the editor.
