Registry
Some item systems can have a Registry, allowing different items to be stored in the content database.
For example, the Item System has a registry that allows different items to be stored globally, sharing a global place for all items to be located in.
Commands
registry add [<name>]
-- depending on the system, the name may be optional, and this will add an item (method depends on the system) to the registry
registry get <name>
-- gets an item from the registry
registry remove <name>
-- removes an item from the registry
