Thanks for both for the answers.
But maybe I should clarify a bit more my question.
I need to have in the metadata, the link of the view of this "level". 
For example, providing my metadata to a third party, they would need to 
have within my metadata the link of the original institution website 
(pointing to this correct level).
So that this third party can easily have a link on their website 
pointing to my website (but at the correct level and not at the top of 
the finding aid or homepage).

Thanks,
Yoann
