Publish NFT eBook
Publish NFT eBook with LikeCoin NFT Book Press
Publish NFT requires the Keplr Browser Extension and LikeCoin on a desktop computer
Publishing an NFT eBook on the blockchain involves the following processes:
Create an epub file and enter metadata
Create an ePub file and enter metadata. First, create the ePub file for the eBook, and ensure that the metadata has been entered and organized. Metadata includes book title, author, cover image, publication date, description, etc. Taking the commonly used ePub editing software as an example:
calibre
In calibre, the "Edit Metadata" button is in the upper left corner of the screen. After organizing the metadata, click "Save to disk".
Sigil
In Sigil, you can press the F8 key to edit metadata on the fly.
Register ISCN
After preparing the ePub file, register it as an ISCN.
Step 1: Upload the file
Visit the app.like.co website and click "Register ISCN".
A pop-up window will appear; click on Keplr to connect the wallet.
Click "Select a file" to upload the prepared ePub file.
The system will automatically split the ePub file content into two files: one is the ePub file, and the other is the book cover image file. Check if everything is okay, then click "Start Upload". The system will upload these two files to the distributed network.
The Keplr wallet will pop up a window several times; click "Approve" to sign and wait for a while.
Step 2: Enter book information
"File Ready" appears, indicating that the file has been successfully uploaded. The system will automatically fill in the information based on the metadata content. The user can change them if they want:
Type: The default is "Book" for NFT eBooks.
ISCN Title: The title of the book associated with the ISCN.
Description: A brief description of the NFT eBook.
Author: The author's name.
Stakeholders: The system will automatically add the author and the ISCN registrant as stakeholders.
Tags: These are used for classification purposes.
Downloadable URL: The file's name of the ePub when it is being downloaded.
URL: The URL of the ePub.
License: The default is "Copyright. All rights reserved" for copyright declaration.
Content Fingerprints: These are URL hashes of the book and its cover. Each pair corresponds to one file, including IPFS and AR (Arweave) formats. Click on the URLs to check whether the content has been successfully uploaded. For instance, the four hashes in the attached screenshot represent the IPFS ePub file, IPFS book cover file, AR ePub file, and AR book cover file.
+Other settings: Click on it to fill in the URL and ISBN fields if required.
After confirming that everything is correct, click "Register".
The Keplr wallet will pop up a window several times; click "Approve" to sign. Be careful not to click "Retry"; just wait for a while.
Step 3: ISCN registration completed
The message "Completed! Here is your ISCN" appears, indicating that the ISCN has been successfully registered. The string of characters in the ISCN ID field will be used when listing the NFT eBook for sale; click to copy it. Note that the '/1' in the picture is the ISCN version number, which is not essential when creating NFT eBooks.
List the Book for Sale
Listing for sale is divided into two steps: minting the NFT eBook and listing it. An analogy to traditional publishing is printing manuscripts into books and placing them on bookshelves for sale.
Step 1: Mint the NFT eBook
Visit the LikeCoin NFT Book Press website, click "Mint NFT", enter the website, and click the "Connect Wallet" link in the upper right corner to connect with Keplr.
In the "Enter ISCN ID or NFT Class ID" field, input the ISCN ID previously registered on app.like.co, and please note that there is no need to include the ISCN version number. Afterward, click "Submit".
If you forget your ISCN ID, you can retrieve it in "My Works" at app.like.co.
The system will automatically extract the basic information of ISCN for you. Fill in other information required in the "By filling required information" tab.
Enter the number of NFTs to mint in the "Number of NFT to mint" field.
If your book file is in ePub format, the system will automatically extract the link to the AR cover and place it in the "Image URL" column.
"External URL (optional)", "URI (optional)", and "Max number of supply for this NFT Class (optional)" can be filled in as needed.
After filling in and confirming that everything is correct, click "Mint". The Keplr wallet will pop up windows several times. Click "Approve" to sign.
The π Success! screen appears, indicating that the NFT has been successfully minted. Click "Continue to publish NFT Book" to complete the listing. Click "View your NFT" to view minted NFT eBooks in Liker Land.
Since it is not yet available for sale, you will see the words "Sold Out".
Step 2: Book Listing
Return to LikeCoin NFT BookPress, click "Continue to publish NFT Book", and the NFT Book Store Management Page will appear.
If you accidentally closed the page, you can enter your NFT Class ID in Step 1 "Enter ISCN ID or NFT Class ID", and you will see "Continue to publish NFT Book". The Class ID is the string after the URL of your NFT eBook. For example, your NFT URL is https://liker.land/zh-Hant/nft/class/likenft1qq06n42guzvt087wxunaajvz3alx6wadq6mfz0yz57gffwsrgrasl2m59x, and the NFT Class ID is likenft1qq06n42guzvt087wxunaajvz3alx6wadq6mf z0yz57gffwsrgrasl2m59x.
