Collections Metadata Standards

Here you can find an example of Metadata json standard, using the ETHITEM front-end best practices:
"image": "",
"image_data": "",
"description": "dasdasd",
"background_color": "#72ca07",
"discussionUri": "",
"externalDNS": "",
"externalENS": "",
"repoUri": "",
"name": "asd",
"symbol": "asd",
"decimals": 1,
"hasDecimals": false,
"originalCreator": "0x748B2D8E120508B23929a6E17387bE7ED418F62D",
"extensionAddress": "0x748B2D8E120508B23929a6E17387bE7ED418F62D",
“extensionCode”: “allthextesioncodeifitsacontract”,
"external_url": "asd.itempesta.eth",
"license_url": "ipfs://ipfs/QmbJWAESqCsf4RFCqEY7jecCashj8usXiyDNfKtZCwwzGb"
--- “Image_data”: Raw SVG image data for if you want to generate images on the fly (not recommended). Only use this if you're not including the image parameter. [NFT Shared Standard] [optional]
--- “description”: A human-readable description of the item. Markdown (and raw HTML) is supported. [NFT Shared Standard] [Mandatory]
--- “background_color”: Background color of the item. Must be six-character hexadecimal without a pre-pended #. [NFT Shared Standard] [mandatory]
--- “discussionUri”: Optional URL to a communication channel (Discord, Telegram, Riot, etc…) related to the collection. [optional]
--- “externalDNS”: Collection homepage on the Web-2 [optional]
--- “externalENS”: Collection homepage on the Web-3 [optional]
--- “repoUri”: URL to a VCS repository of the project (i.e. GitHub, GitLab, GitTea, etc…) [optional]
--- “name”: Name of the collection. [NFT Shared Standard] [mandatory] [wizard]
--- “Symbol”: Ticker/Symbol of the collection [mandatory] [wizard]
--- “Decimals”: Amount of decimals supported by the Collection [mandatory] [wizard]
--- “hasDecimals”: True if during the creation wizard of a collection you enable support for 18 decimals, else false. [mandatory] [wizard]
--- “originalCreator”: address of the collection creator. [mandatory] [wizard]
--- “extensionAddress”: Address of the extension [mandatory] [wizard]
--- “extensionCode”: String containing the source code for the extension [mandatory only if the extensionAddress points to a contract] [wizard]
--- “external_url”: URL Subdomain.item.eth [wizard]
--- “license_url”: IPFS link to the license file
Note: When passing the JSON externally it should follow this same approach (aka start with the IPFS protocol) ipfs://ipfs/QmVyPrsDrfwRbJgZYy1mRmb5qYPpPJFx2CUxPMTCoUmv6V
This requirement guarantees total compatibility with NFT Shared Standards. This should be the form followed by the URI returned by the “uri()” method.
