For people who have problems with source code of Modisco, don't worry it's normal ;-)
We are on the way to move parts of code to EMF Facet, a new project dedicated to metamodel extension (see http://www.eclipse.org/modeling/emft/facet). And we are adding links to this new project.
Of course, it could happens some errors as it still unstable.
So don't forget to update your links and keep in touch to know when the transition will end.
