Hi Jerome,

Well Doug answered most of it. You do need handles to tie the data 
together. It is not the Gramps Exhibit that adds handles, it is the 
user-scripts that generate them. At present Gramps Exhibits just display 
the GrampsXML you feed them. Since the situation with duplicate handles 
is unclear, the user-scripts will generate different handles every time 
you search for the same data. Perhaps in the future when Gramps has 
decided how to handle duplicate handles and archives give certificates 
some kind of global ID, the handles may be unique per certificate. But 
that is still far in the future.
