[Koha-devel] notforloan rule

Hi koha-devel, Working on C4::Reserves2 and associated scripts, I'm wondering what is the rule to say an item is not for loan? In the database, we have itemtypes.notforloan and items.notforloan. In the authorised values for category "STATUS" I have 5 values from 0 to 5 (with no 3). In my items table, most of my items have NULL as notforloan value. In my itemtypes table, notforloan is either "loanable" or "excluded from loan". Should I consider that if items.notforloan is null then the correct value is the itemtypes one?
