@ -69,6 +69,16 @@ Here's an example.
* In step 1, Alice **publishes** her dataset with Ocean: this means deploying an ERC721 data NFT contract (claiming copyright/base IP), then an ERC20 datatoken contract (license against base IP).
* In step 2, she **mints** some ERC20 datatokens and **transfers** 1.0 of them to Bob's wallet; now he has a license to be able to download that dataset.
### Revenue
By default revenue is sent to the owner of the data NFT and this automatically updates when the data NFT is sent to a new owner. Owning a data NFT therefore has an explicit value - the revenue stream associated with selling the digital asset.
In some situations, you may want the revenue to be sent to another account rather than the owner. This can be done by setting a new **payment collector**. Changing the payment collector can be particularly useful when the data NFT is owned by an organization or enterprise, rather than an individual.
In order to set a new payment collector, you need to visit the asset detail page and then click on “Edit Asset” and then scroll down to the field call “New Payment Collector”. You need to add the new Ethereum address and then click “Submit“. You will then need to sign two transactions to finalize the update.

### TemplateIds
Each data NFT or a datatoken is cloned from pre-defined template contracts. The _templateId_ parameter refers to the template from which a data NFT or datatoken is created. The templateId can be set while creating data NFT/datatoken. The templateId is stored in the code of the smart contract and can be retrived using `getId()` function. Currently, Ocean protocol supports 1 template type for data NFT and 2 template variants for datatokens, namely: **regular template** and **enterprise template**. Each template supports the same interfaces but differs in the underlying implementation and can have additional features.
