+The proposed module is a base module for NFT app logic. Its goal is to provide a common layer for storage, basic transfer functionality and IBC. The module should not be used as a standalone.
 Instead an app should create a specialized module to handle app specific logic (eg: NFT ID construction, royalty), user level minting and burning. Moreover an app specialized module should handle auxiliary data to support the app logic (eg indexes, ORM, business data).
 
 All data carried over IBC must be part of the `NFT` or `Class` type described below. The app specific NFT data should be encoded in `NFT.data` for cross-chain integrity. Other objects related to NFT, which are not important for integrity can be part of the app specific module.

 We propose two main types:
 
 * `Class` -- describes NFT class. We can think about it as a smart contract address.
-* `NFT` -- object representing unique, non fungible asset. Each NFT is associated with a Class.

 This ADR doesn't specify values that `data` can take; however, best practices recommend upper-level NFT modules clearly specify their contents.  Although the value of this field doesn't provide the additional context required to manage NFT records, which means that the field can technically be removed from the specification, the field's existence allows basic informational/UI functionality.
