TaggableItems
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Taggable Items
A Minecraft 1.21.5 datapack that allows you to tag items with custom data
Players can add custom data to items with new triggers.
Item Data
Player UUID
When a player privatizes an item, it gets a PlayerUUID added to it. Independent from UUID.
Custom UUID
Custom UUID is assigned by player, it is a field that separates it from other items.
Checking for Item Data
Using the command:
/trigger check_item_info
You can view an item's custom data and UUIDs.
Adding Custom Data
/trigger add_custom_data
Allows players to add custom text data to held items.
Privatizing Items
