Products' import: attributes

Hello everybody,
I’m trying to import products into a new Tryton setup, using the product attribute module. There is a products’ attribute set called “AS1”, which contains “year” and “material”.

Which import table headers do I need to get these attributes imported?

Thanks a lot in advance, Wolf
