Master Core

It is a structure designed to fulfil the role of identification and on-chain registration of a Master intellectual property protected by Master Recording Rights. By the legal nature of music assets, part of this information is immutable over time, such as the title, the names of the performers, and the parameters of on-chain registration. Another part of the information included in the Master Core is mutable and is represented through standard parametric structures and custom parameters.

A generic IP Core structure is composed of the following fields:

Field	Description	Type
ISRC_code	It is the ISRC code of the registered musical work
title	Title of the song	String
performers	It contains all the names and IPI codes of the creators	Struct
IP_Core	It is the data structure containing the references of the IP cores of the music work being registered in the master	Time
registration_id	Registration id	String
registrant_identity	Verified identity of the registrant	String
registration_source	Execution layer identifier where the registration has been made	String
Ip_asset	The connection identifier with the execution layer where the file representing the asset is stored on-chain	Array
custom	Custom parameters that can be added to the IP Core	Array
