In order to make it a bit less painless to work with Eclipse EMF (we
    would have to export the plugins, restart Eclipse, etc. etc.), we start
    another Eclipse in the IDE. This instance is called the 
Runtime
    Workbench
. Therefore select the
    xpand.demo.emf.datamodel.edit project and choose from
    the context menu  → . 
If you are using a Mac or *nix you should now open the workspace
    preference page and change the default encoding to ISO-8859-1.[4]Import the xpand.demo.emf.datamodel
    project from your original workspace.[5] Note that importing the project does not physically move the
    files,[6] so you can have the project be part of both workspaces at
    the same time.
Create a new Xpand Project[7] called xpand.demo.emf.datamodel.generator. Do not
    choose the option "Generate a simple example". 
Your Xpand project will already be configured for use of EMF models. You can check this in the project properties dialog:
