Abstract
This standard introduces a smart contract interface that can represent a batch of non-fungible tokens of which the ordering information shall be retained and managed. Such information is particularly useful if tokenIds are encoded with the sets of unicodes for logographic characters and emojis. As a result, NFTs can be utilized as carriers of meanings.
