Metadata
Our Metadata for now lives on Arweave, a permanent, cheap, and decentralized storage platform. You can either store the metadata on NEAR as the NEP 171 suggests, this would be extremely expensive if we are storing thousands for say a stadium seating. 

We use the reference to get the entire metadata block (title, description, media) to save on space.
1
type TokenMetadata = {
2
  title: string|null, // ex. "Arch Nemesis: Mail Carrier" or "Parcel #5055"
3
  description: string|null, // free-form description
4
  media: string|null, // URL to associated media, preferably to decentralized, content-addressed storage
5
  media_hash: string|null, // Base64-encoded sha256 hash of content referenced by the `media` field. Required if `media` is included.
6
  copies: number|null, // number of copies of this set of metadata in existence when token was minted.
7
  issued_at: number|null, // When token was issued or minted, Unix epoch in milliseconds
8
  expires_at: number|null, // When token expires, Unix epoch in milliseconds
9
  starts_at: number|null, // When token starts being valid, Unix epoch in milliseconds
10
  updated_at: number|null, // When token was last updated, Unix epoch in milliseconds
11
  extra: string|null, // anything extra the NFT wants to store on-chain. Can be stringified JSON.
12
  reference: string|null, // URL to an off-chain JSON file with more info.
13
  reference_hash: string|null // Base64-encoded sha256 hash of JSON from reference field. Required if `reference` is included.
