Hi, Thanks for this link ; in fact I already downloaded "zc.copy" but just forgot to take a look at it... In fact, after looking at "zc.copy" package, I finally used the "original" zope.copypastemove package function to duplicate my content because it better feets my needs, without duplicating a set of informations as zc.copy does but just keeping a link on them. The last problem I still have is that some of the informations stored into object's annotations have to be indexed into a set of catalogs. While these informations are indexed correctly when annotations are created "by hand" in the "normal" way, it's not the case when content is duplicated "in a whole". Any idea ? Should I iterate over object annotations and check for ones that should contain indexable content ?
