An ISBN is an International Standard Book Number. ISBNs were 10 digits in length up to the end of December 2006. Since January 1, 2007 they now consist of 13 digits. ISBNs are calculated using a specific mathematical formula and include a check digit to validate the number.
PSIM stands for Published NFT Standard Identification Metadata.
It’s a unique NFT identifier of a Smart Contract/CID/Token ID that’s assigned by Publishednft.io It’s primarily used for NFT-identification within their product database of items.
For books, the PSIM is the same as the ISBN or ASIN number. For all other products, a new PSIM is created when an item is uploaded to Published NFT’s database.
Each ISBN consists of 5 elements with each section separated by spaces or hyphens. Three of the five elements may be of varying length:
- Prefix element — currently this can only be either 978 or 979. It is always 3 digits in length
- Registration group element — this identifies the particular country, geographical region, or language area participating in the ISBN system. This element may be between 1 and 5 digits in length
- Registrant element — this identifies the particular publisher or imprint. This may be up to 7 digits in length
- Publication element — this identifies the particular edition and format of a specific title. This may be up to 6 digits in length
- Check digit — this is always the final single digit that mathematically validates the rest of the number. It is calculated using a Modulus 10 system with alternate weights of 1 and 3.
- This data will be remapped & recreated with smart contracts and IPFS CID for ASIM creation.
Note: PSIMs are only guaranteed to be unique on Flow scan or and IPFS. This means different national Blockchains may use different PSIMs for the same product.

The ISBN (International Standard Book Number) and PSIM (Published NFT Standard Identification Metadata) play crucial roles in the identification and organization of assets, particularly in the context of Published NFT and its sellers and collectors. While ISBNs are widely recognized and used for books, PSIMs serve as unique identifiers for NFTs within Published NFT's product database.
The ISBN is a standardized numbering system used to uniquely identify books. It consists of 13 digits since January 1, 2007, and is calculated using a specific mathematical formula. The ISBN includes various elements such as the prefix, registration group, registrant, publication, and a check digit for validation. It ensures that each book is assigned a distinct identification number, facilitating inventory tracking, bibliographic organization, and copyright protection.
In the realm of NFTs, Published NFT has introduced the concept of PSIMs. For books, the PSIM is equivalent to the ISBN or ASIN number, while for other products, a new PSIM is generated when an item is uploaded to Published NFT's database. The PSIM serves as a unique identifier for NFTs associated with a specific Smart Contract/CID/Token ID. It enables blockchain and IPFS data referencing, inventory tracking, and efficient indexing for search and browsing functionalities on Publishednft.io.
PSIMs are integral to Published NFT's product database structure, allowing shoppers to search for products by drilling down through multiple categories or directly by using the PSIM number. By using the correct PSIM, sellers ensure that their products are accurately organized and easily discoverable by potential buyers. Minting NFTs to an existing PSIM metadata or creating a new one is a prerequisite for listing any product on Published NFT.
In addition to facilitating product organization and searchability, PSIMs and ISBNs hold significance for asset ownership and copyrights. They provide a standardized framework for identifying and verifying the uniqueness of an asset, be it a physical book or a digital NFT. This aspect is crucial for establishing and protecting ownership rights and ensuring the proper attribution of intellectual property.
By leveraging PSIMs and ISBNs, Published NFT empowers sellers and collectors to participate in a comprehensive ecosystem where assets are accurately tracked, discoverable, and protected. These identification systems form the foundation for a streamlined and optimized shopping experience, ensuring that users can easily navigate, search, and acquire the products they desire while maintaining the integrity of intellectual property rights.

The ISBN is part of the International Standard Bibliographic Description (ISBD), which was prescribed by the International Organization for Standardization; delegates adopted the numbering system in 1969. The ISBN provides a standard for the arrangement of bibliographic information in single- and multivolume publications. Its numbers are assigned by publishers and administered by designated national standard book numbering agencies — e.g., the R.R. Bowker company in the United States, Nielsen Book in the United Kingdom, the National Library in Brazil, the Agentur für die Bundesrepublik in Germany, and the Library Authority in Ghana. Each ISBN is identical with the Standard Book Number, originally devised in the United Kingdom, with the addition of a preceding national group identifier. In 2007 the ISBN format changed from 10 digits to 13 digits.
