ERC proposed by [Iain Nash](https://twitter.com/isiain) and [Louis Garoche](https://github.com/lgaroche) # EIP Overview This ERC is defining a standardized way to identify underlaying content and associated data of an NFT through on-chain getter. It is solving the problem of how platforms (wallets, dApps...) can define what kind of file was uploaded and adjust UI based on that. NFT contracts to provide a contentType getter so clients can identify the type of NFT and how to fetch metadata. This EIP is sort of extension for NFT projects which are using metadataURI, getSVGData, getMidiData,contentURI and contentHash getter functions. This EIP should be implemented alongside with ERC-1155/ERC-721 and keep the existing metadata URI schemes on top of new content types to compliment this standard metadata associated with the NFT content.
