EIP-6596: Historical Asset Metadata JSON Schema establishes a metadata standard for Historical Asset Tokens (HATs).
HATs are tokens that represent a specific historical asset, such as a collectible or a rare item, and provide comprehensive context and provenance needed to establish historical significance and value, with the goal to enhance the discoverability, connectivity, and collectability of historically significant HATs.
Based on our experience tokenizing historical artifacts, and we have curated and defined dozens of metadata attributes, captured in the EIP. The proposed attributes had been shared with organizations working in NFTs and preserving historical artifacts such as Aniomca Brands, British Museum and Christie’s.
By extending the Metadata JSON Schema defined in ERC-721 and ERC-1155, we aim to create a ubiquitous language on top of widely accepted NFT standards, that would historical NFTs to flow between applications and conversations.
