So if I understand correctly, we all agree that there are some well-defined CSV elements that can be identified by a vocabulary (id, column name, etc.) and we map them to other well-defined elements defined in each language (e.g. attributes), possibly identified by another vocabulary. 
We could provide a default mapping per language (to allow easily converting CSV to another language), and let users with specific needs override it. So, I agree on #3/#4.
