Item Source

CoreLib Item Source provides a stable way to identify items from Vanilla and external item ecosystems. It is better than relying on display names or lore.

Supported sources

Source	Aliases
Vanilla	vanilla, minecraft, v
CraftEngine	craftengine, ce
ItemsAdder	itemsadder, ia
NeigeItems	neigeitems, ni
MMOItems	mmoitems, mi
EmakiItem	emakiitem, ei
Nexo	nexo, no

Advice

Use stable IDs for recipe materials, rewards, conditions, and station matching. Avoid judging items by display name or lore because they may be modified by other plugins or rebuilt by CoreLib Assembly.

CraftEngine, ItemsAdder, and Nexo item sources can also be passed to the placeblock action when the source represents a custom block.
