Background

The Writing NFT introduced by Liker Land is designed especially for a single piece of article or post. The idea is similar to the traditional book publishing flow as an analogy, but the solution, however, tackles some specific issues for a single piece of writing.

NFT Class metadata

Each writing NFT class represent a creative work registered on an ISCN. To allow easier search and collection of all Writing NFTs created by a same creator, nft_meta_collection fields would be used. A dynamic API is used as uri to provide dynamic metadata according to mint purchase status.

key	value	description
name	Writing NFT - {ISCN name}	Name of ISCN prefix with Writing NFT
symbol	WRITING	WRITING is used as symbol
uri	https://api.like.co/likernft/metadata?iscn_id={iscn_id}	Dynamic API from api.like.co, query by ISCN ID
metadata
metadata.nft_meta_collection_id	likerland_writing_nft	ID of the Writing NFT meta collection
metadata.nft_meta_collection_name	Writing NFT	Name of Writing NFT meta collection
metadata.nft_meta_collection_descrption	Writing NFT by Liker Land	Description of Writing NFT

NFT Instance metadata

In Writing NFT, every instance of NFT in a same class should be homogeneous. A randomized ID is used to prevent user from distinguishing the minting order. A dynamic API is also used as image to provide dynamic image according to mint purchase status.

key	value	description
id	writing-{uuid}	Randomized uuid v4 prefixed with writing
uri	https://api.like.co/likernft/metadata?class_id={class_id}&nft_id={id}	Dynamic API from api.like.co, query by class id and nft id
metadata
metadata.name	Writing NFT - {ISCN name}	ID of the Writing NFT meta collection
metadata.image	https://api.like.co/likernft//image/class_${classId}.png	Name of Writing NFT meta collection
