Thank you. I was hoping the standard would describe structure for discussing the attributes of the nft ('attributes' field on the zombie). Looks like there is more work to do. A future CIP perhaps.

<p>I realize that metadata for nfts has no official standard. However, many 3rd parties render nfts and their attributes which means they are reading meta data according to one or more schemas.</p>

What is the standard metadata schema for nfts
# What is the standard metadata schema for nfts

(Asked by: username_0 on 2021-12-17)

I realize that metadata for nfts has no official standard. However, many 3rd parties render nfts and their attributes which means they are reading meta data according to one or more schemas.
Here is an example of the zombie metadata:
{
   96580bbc4fe27ac0d127db3f8a0dc698c58d303d8cae870f5771f336: {
      ZombieChains00690: {
         Project: "Zombie Chains",
         attributes: {
            Background: "Purple",
            Chains: "None",
            Clothing: "Biker",
            Earrings: "None",
            Eyes: "Zombie",
            Hat: "Baseball",
            Mouth: "Stitches",
            Nose: "Solid",
            Skin: "Red",
            Weapon: "Sword"
         },
         copyright: "2021 Zombie Chains",
         image: "ipfs://QmQTkayfG1GWzenfEm65DLyYVL7MS6sSfWZQyPuFm6XiEV",

         type: "image/png",
         website: "https://zombiechains.io"
      },

Does anyone have documentation or knowledge about metadata nft standards?

There is a metadata standard. You can check it here: CIP-0025
{
  "721": {
    "": {
      "": {
        "name": ,

        "image": ,
        "mediaType": "image/",

        "description": 

        "files": [{
          "name": ,
          "mediaType": ,
          "src": ,
          
        }],

        
      }
    }
    "version": "1.0"
  }
}

Not all follow that standard.
