This article is a stub. You can help by expanding it.

NBT tags are used to specify information for items and entities created with the "/give", "/summon", "/tellraw" (for the JSON message), "/fill", "/blockdata", "/setblock", and "/clear" commands.

Each tag has the format <tagname>:<value> ; multiple tags are separated by commas. The contents of List tags are enclosed in square brackets [], while the contents of Compound tags are enclosed in curly braces {} – note that the entire data tag is itself a Compound tag. Tag names are case-sensitive.
