I am not at the moment, but as it is necessary for the future I'm trying it.

For the moment I'm not able to load the UML-model. I get an exception:

Cannot create a resource for 'seclinks.uml'; a registered resource 
factory is needed at 
org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.getResource(ResourceSetImpl.java:394)

So I tried to do a "UMLResouceFactoryImpl" my way but apparently took 
the wrong way. I even get a exception when loading the henshin-file:

Exception in thread "main" java.lang.UnsupportedOperationException

Thanks in advance,
