Publish Data NFTs
How to Mint and Publish Data NFTs Using the Ocean Market
Ocean Protocol has a convenient marketplace, called the Ocean Market, for publishers and consumers of data. What data, you ask? This data spans anything from .
XLSXfiles to images, audio, videos, algorithms in any language, or combinations of all these things! There is no exhaustive list of what type of data can be published on the Ocean Market.
The publishing process on the Ocean Market both mints (i.e. creates) a data NFT and a corresponding datatoken for your IP. The data NFT stores your IP, and the datatoken controls access to it. If you publish your music IP on the Ocean Market, for example, then a data NFT containing your music and its datatoken are minted during the publishing process. When consumers purchase the datatoken, then they gain access to download/use your data NFT's music.

Mandatory fields are marked with *
- Access Type*An asset can be either a downloadable file or a compute job on a dataset which buyers can run their algorithm. Through download, buyers will be able to download the data in the NFT. Through compute, buyers will be able to purchase a compute job on a dataset to see an output feed (see Compute-to-Data).
- Provider URL*The Provider server encrypts the URL to the data and allows for the asset to be downloaded by buyers or for compute jobs.
- File*The direct URL to the data. Provider encrypts this field before publishing the asset on-chain to hide the source of the data. The direct URL to the file needs to be publicly accessible so that the file can be downloaded by buyers (data hosted behind firewalls will not work!). If the file is hosted on services like Google Drive, then the URL needs to point directly to the data asset file. Also, the file needs to have the proper permissions to be downloaded by anybody.
- Sample fileAn optional field where publishers can provide a URL to a sample file of the data. Including a sample file helps to persuade buyers that the data is in a suitable format for their needs. The buyers can access it before buying the dataset. This field is editable after the asset publication.Provider encrypts this URL before publishing the asset on-chain.
- Timeout*This field specifies how long the buyer can access the dataset after the dataset is purchased. This field is editable after the asset publication.

The publisher needs to choose a pricing option - fixed or free - for the asset before publishing the data asset. The pricing schema is not editable after the asset publication.
There are 2 pricing option tabs for asset publication on Ocean Marketplace.
With the fixed pricing schema, the publisher sets the price that buyers will pay to download the data asset.
With the free pricing schema, the publisher provides an asset that is free to be downloaded by anyone.

To publish your NFT on-chain, you must go through three steps including signing two transactions with your wallet. Note: this will cost some gas fees!
Transaction Signature 1 - Deploy data NFT and datatoken
Transaction Signature 2 - Deploy data NFT and datatoken
Now, your data NFT is successfully published and available in the Ocean Market!
Your data or algorithm NFT is *published* on-chain once you complete the flow. However, you are not selling the actual NFT on-chain - you are selling datatokens that give buyers access to the NFT's data. More on this distinction in the Ocean Basics video tutorial.
