5.5 Updatable profile

This profile is defined in the circumstances where music metadata may change over time, that consequently the rights controllers will need to have the ability to update that metadata and that the rights controllers need the ability to take-down any Primary Resources. This profile is designed to also cater for cases where one or more of the controllers of the rights to the music contained in the NFT change after the NFT is minted.

When communicating to an NFT Minting Service that an NFT Issuer wishes to issue a release using this profile, the NFT Minting Service shall, subject to contractual obligations:

  • Place all data associated with the Music NFT such as the reference to the Smart Contract, any identifier(s) for the resources contained in the Music NFT, data describing the Music NFT and some of the commercial terms, for example, “this is NFT x of y” to express artificial scarcity on-chain or in a decentralised data store;

  • Place all available identifiers for the release, the resources and the underlying musical works contained in the Music NFT as defined in Clause 5.3.2 either on-chain or into a decentralised data store;

  • Place all descriptive metadata for the release, the resources and the underlying musical works contained in the Music NFT as defined in Clause 5.3.3 and all artist and contributor names and identifiers as defined in Clause 5.3.4, in a centralised data store where the NFT Issuer or other interested parties defined at the time of minting the Music NFT may, at a later stage, trigger an update of the data;

  • Place all rights metadata as defined in Clause 5.3.5, including the names and identifiers of rights controllers, in a centralised data store where the NFT Issuer or other interested parties defined at the time of minting the Music NFT may, at a later stage, trigger an update of the data;

  • Place a wallet for all rights controllers either on-chain or in a decentralised data store. This wallet may, as set out in Clause 6.1, be a multi-signatory wallet or an “escrow” wallet controlled by the NFT Minting Service;

  • Place all Primary Resource files (as defined in Clause 4 of Part 2 the ERN standard) in a centralised data store where the NFT Issuer or other interested parties defined at the time of minting the Music NFT may, at a later stage, trigger an update and/or take-down the resource; and

  • Place all Secondary Resource files (as defined in Clause 4 of Part 2 of the ERN standard) in a centralised or decentralised data store.

In addition, the NFT Minting Service shall update the rights controller information (including, if relevant, their wallets) of the Music NFT in accordance with this Clause 5.5 once it has received updated rights controller information.
