-### Data Structures
-
-- **Owners Mapping**: A mapping from `tokenId` to an enumerable set of owner addresses.
-
-  ```solidity
-  mapping(uint256 => EnumerableSet.AddressSet) internal _owners;
-  ```
-
-- **Balances Mapping**: A mapping from owner addresses to the number of tokens they own.
-
-  ```solidity
-  mapping(address => uint256) private _balances;
-  ```
-
-- **Providers Mapping**: A mapping from `tokenId` to the provider's address.
-
-  ```solidity
-  mapping(uint256 => address) private _providers;
-  ```
-
-- **Transfer Values Mapping**: A mapping from `tokenId` to the `transferValue` fee.

    - Transferring ownership adds the new owner to the ownership list without removing current owners. This approach reflects the shared nature of digital assets.

-
-   - The smart contract tracks the list of owners for each MO-NFT using the `_owners` mapping.

    - During a transfer, the specified `transferValue` fee is transferred to the provider. The contract must have sufficient balance to cover this fee.

    - Owners can remove themselves from the ownership list using the `burn` function.

-### Value Depreciation
-
-1. **Value Model**:
-
-   - As the number of owners increases, the value of the MO-NFT may decrease to reflect the reduced exclusivity. This is an optional model and can be implemented at the application level.
-
-2. **Depreciation Mechanism**:
-
-   - The value depreciation model can be defined based on the asset type and distribution strategy. This standard does not enforce a specific depreciation mechanism but acknowledges its importance.
