JSON is the commonest format for NFT metadata and has no restrictions on the information’s construction as a result of it’s a light-weight format.
How does NFT metadata work?
An integral part of nonfungible tokens that lets them function is NFT metadata.

The metadata saved on the IPFS community is then returned to the sensible contract as a hash and pinned to the protocol. The resultant URL is recorded in a self-executing contract’s storage and linked to the ID of the related token.
The identical URL resolves to a JSON object on the net with a transparent construction and set of properties.
