Documentation

🎼 Allfeat MIDDS

Music Industry Decentralized Data Structures (MIDDS) for the Allfeat blockchain ecosystem.

Overview

MIDDS provides standardized, type-safe data structures for music industry entities with full Substrate runtime compatibility.

Core Entities

Entity Description Standard ID
Musical Works Compositions and songs ISWC
Party Identifiers Artists, labels, publishers IPI/ISNI
Releases Albums, EPs, compilations EAN/UPC
Tracks Individual recordings ISRC

Quick Start

use allfeat_midds::{
    party_identifier::Ipi,
    musical_work::Iswc,
    shared::conversion::Validatable,
};
use std::str::FromStr;

// Create identifiers
let ipi: Ipi = 123456789;
let iswc = Iswc::from_str("T1234567890").unwrap();

// Validate (std feature required)
#[cfg(feature = "std")]
{
    assert!(iswc.validate().is_ok());
}

Features

  • 🔒 Type Safety: Strong typing with validation
  • ⚡ Performance: Optimized for on-chain storage
  • 🌐 Dual Types: SDK and Runtime type separation
  • 📏 Standards Compliant: Music industry standards
  • 🧪 Benchmarking: Built-in benchmark helpers

Benchmarking

use allfeat_midds::{benchmarking::BenchmarkHelperT, track::Track, Midds};

// Generate test data with varying complexity
let track = <Track as Midds>::BenchmarkHelper::variable_size(0.5);
let min_track = <Track as Midds>::BenchmarkHelper::min_size();
let max_track = <Track as Midds>::BenchmarkHelper::max_size();
