​In March 2022, we in the project team began testing the hypothesis about the rights to RIA (the Result of Intellectual Activity) objects in the NFT wrapper, came to the conclusion that it is necessary to integrate two types of licenses into the metadata for each work (this is in our case, if it’s just a collection with the creator’s rights, then. .1 is sufficient and necessary).
1. To the object. Example for collection TON Fingerprints
2. For derivative works (in our case, these are source files for our NFTs, in vector format, inside each svg there is also a license from clause 1, + a permissive license), example:

...
xmlns:cc = "http://creativecommons.org/ns#">
<cc:license rdf:resource="http://creativecommons.org/publicdomain/zero/1.0/deed.en"/>
<cc:permits rdf:resource="http://creativecommons.org/ns#Reproduction"/>

Permissive license (not fully implemented, only as an addition to json, with some general information about this):
1. In Creative Commons Zero (CC0) format, allows you to create creative remixes with benefits for both the original and derivatives.
2. Emphasis on low accuracy + metadata. Low fidelity allows you to remix with high fidelity (Pixel Art -> 3D Graphics).
3. Classification of metadata by source packages in CID. Assembly from ipfs(x1+x2+...xn) (it is necessary to open part of the template, or generation algorithms)

Subtotal: The owner of the NFT is independent of the copyright of the resulting image that is referenced. Copyright is assigned to the creator. This limits the owner (buyer) to only use the link. The owner is not allowed to use the image in any way, especially for commercial purposes. the immutable time series mechanism in the TON network helps legitimize this link. Everything is logical for the creator, as well. he does not lose control over his RIA, because if derivative works of the original carry a negative connotation, it will harm the original creator. CC0 enhances value because: the creator can profit not only from the original work, but also from derivative works, along the value chain.

Model: The original author chooses CC0, for a reason

1. Author A creates a content under the CC0 license
2. Sells NFT #1 CC0 content to person B
3. Person B decides to create derivative content CC0
4. Person B sells NFT derivative #2 of CC0 content to person D
5. Person G liked the derivative work and decides to buy the original NFT #1
6. Thus, Person A receives a role from the sale. Person B receives income from the sale of the derivative work + the (re)sale of the original NFT. Person G is a happy collector of both the original work and the derivative.
7. Person G decides to create a derivative work of NFT #2 or NFT #1...etc.
