Publish

Once you've configured the RPC environment variable, you're ready to publish a new dataset on the connected network. The flexible setup allows you to switch to a different network simply by substituting the RPC endpoint with one corresponding to another network. 🌐

For setup configuration on Ocean CLI, please consult first install section

To initiate the dataset publishing process, we'll start by updating the helper DDO(Decentralized Data Object) example named "SimpleDownloadDataset.json." This example can be found in the ./metadata folder, located at the root directory of the cloned Ocean CLI project.

The provided example creates a consumable asset with a predetermined price of 2 OCEAN. If you wish to modify this and create an asset that is freely accessible, you can do so by replacing the value of "stats.price.value" with 0 in the JSON example mentioned above.

Now, let's run the command to publish the dataset:

npm run cli publish metadata/simpleDownloadDataset.json

Publish dataset

Executing this command will initiate the dataset publishing process, making your dataset accessible and discoverable on the Ocean Protocol network. 🌊
