Quality level rating by a board of food experts for this particular candy. (Some samples were taken).

the upc, barcode, and expiration date, and how many types the expiration date has been “corrected”. (The administration of this particular store is just a little crooked.)

Structural metadata:

great analogy…i prefer payday though. whole peanuts instead of creamy peanut butter.

the metadata would be on the upc barcode, wouldn’t it? it means something the the computer, but totally invisible to the user/eater.

that is a good description I like to eat them and that just makes me want to eat them more..
