Actually, what I want to make sure is that
1. certain annotations that belong to a certain instance are also cloned when 
the user makes a copy of that instance using the GUI.
2. annotations of removed instances are also removed when the user deletes the 
instance using the GUI.

My problem with your suggestions is that my code is not aware of user/gui 
triggered instance cloning events. Possibly, some kind of listener would be 
useful here but I haven't found any. Any hints to solve this issue?
What I meant with orphaned annotations are annotations that are left in the 
annotation ontology when their corresponding entitiy (in the actual ontology) 
is deleted by any means. Is there a way to either have it deleted upon entitiy 
deletion or pruned some time afterwards?

Thanks
Simon
