This is exactly what we should be discussing. It may simply be a matter 
of who you ask and how they are working. I am not familiar with any 
agency in France, so I will just assume that they work the way you 
described. How would those agencies decide on which sources, e.g., 
vocabularies, are authoritative, trustworthy, will be maintained, will 
persist (e.g., in terms of their URI), and so forth. I assume they would 
not be okay with just using  any external source, right? These are the 
questions that I am getting all the time. Btw, also from libraries as 
long-term preservation is one of their key goals. Other issues that are 
often raised center around ownership, licensing, copyrights, and so 
forth. Also, have you seen the related soft reuse discussion on the 
semantic web list?
