I have been reading about using command blocks, and I come across the term "data tag" a lot. Can anyone explain what this is?

For example:

/summon <EntityName> [x] [y] [z] [dataTag]
  • Got a link or quote showing the usage in context? Are you thinking of an NBT Tags perhaps?

The data tag is a piece of text that allows you to assign NBT (Named Binary Tag, see here) data to items or entities.

There are a number of different commands that can be used with data tags to assign NBT data. For more information, check out this post on the Minecraft subreddit.
