In the "New Kermeta 3 project" wizard that pops-up if we right-click on the *.melange" file or on the GEMOC Sequential xDSML Project, the user has to select the Ecore model file, even though this file is in the basic case directly referenced in the *.melange file. With language inheritance etc. the automatic inferrence of the Ecore file location becomes more complicated but should be still doable.
