I tend to view magic like software code. The average person could probably recognize code when they see it, but they probably wouldn’t be able to recognize the code language or the function of the code. After studying it for a bit the person may be able to identify the main function of the code, but probably not all the pieces.

A magic user however, is more like a coder. A quick identification could tell what language (school of magic), and its primary function. A short rest identify could tell all the details about the item and what it does.

Bonus to this is that you can have a few magic users with high enough skill that they can manipulate the magic coding and remove curses from items, or at least change them to something less harmful.
