Re: draft for "Canonical Processes" Use Case and updates to the UC and Req document

Hello Felix,

I could probably come up with an example, I could also borrow the one  
developped by Raphael at the workshop of the SAMT conference, if this  
could be authorised :)
The problem is not so much of passing on metadata as such, it is that  
the metadata are encoded in different formats that are not dealt with  
in the other processes, although some properties might be interesting  
to propagate: some keywords or tags, creating date etc can be assigned  
at different moments in the life cycle, but expressed in different  
metadata schemas. Which is the part where the Ontology could have a  
role to play. If I understood correctly, of course :)

Best,
Véronique
