Paolo,

In the cultural heritage I've seen cases that are similar but not 
exactly like your use case.  Two observations might be useful:

1. Sometimes two agents work on the same artifact but have a different 
role in its creation, e.g. the author versus the publisher of a book, or 
the artist versus the printer of a graphical print. In these cases it is 
common to model the different roles explicitly, along with the dates, 
places etc that are associated with the different roles. You can have 
the same situation with annotations, and I think you can achieve all of 
this with subclasses/subproperties in OA.  The special semantics of the 
roles, however, might get lost if the data was processed by a general OA 
application.

2. Sometimes there are really two annotations, one annotating the work 
and a second annotating the first annotation.  We use this, for example, 
to model annotations that arise when one agent is tagging or rating the 
annotation of another agent. So in your case you could have one 
annotation modeling the orginal annotation and one annotation modeling 
the things you wanted to say about the creation process of digitizing 
the first annotation. Again, OA allows annotations to be the target of 
other annotations, so there is no problem there, while it remains 
questionable how other OA applications would treat them.

Hope this helps,

Jacco
