How Does the Metadata in an NFT Relate to the Token Standard?

The token standard (e.g. ERC-721) defines a specific function that points to the NFT's metadata, which is typically stored off-chain (e.g. on IPFS).

The metadata is a JSON file that contains the unique attributes of the NFT, such as its name, description, image link, and other properties. The standard ensures a consistent way for wallets and marketplaces to read and display this unique information.
