Anyone can tell an item is magical by handling it, no detect magic needed. Detect magic speeds up the process and works on other things besides magic items.
Anyone can spend a short rest focusing on a magic item and identifies all of it's properties, besides curses, and artifacts can break this rule too.
The identify spell only speeds up the process, if cast as a ritual it takes 11 minutes instead of a short rest (1 hour), if cast using a spell slot it takes 1 minute. The end result is the same as anyone focusing on the item for an hour, you do not reveal any curses.
Attunement, it takes an hour to attune an item to you (a short rest) you know you need to attune it to you because you discovered this when you identified it, see above.
You may only have three items attuned to you at once.
Most cursed items require attunement and that is how they get you once attuned you are stuck, until someone casts the 3rd level spell Remove Curse.
Attunement also keeps you in the know of how many charges an item has for those pesky wands and staves that recover a variable number each day and if you expend the last one it has a chance of being destroyed, the attuned user knows the number of charges at all times.
IE I run it RAW.
