It threw an exception and I've also figured out the problem now. As 
shown in the recipe (--> getExtendedMetaData()) I'm putting two entries 
into the ResourceSet's package registry.
I wanted to find out why the "package not found" exception occurs, so I 
set a breakpoint on EPackageRegistryImpl.getEPackage(..) and inspected 
the map contents. None of the two entries were mapped...

I've now modified the getExtendedMetaData() method to put the entries 
into EPackage.Registry.INSTANCE and now everything works!

Thank you very much for your help!

Best regards,
