oximedia-archive

Media archive verification and long-term preservation system for OxiMedia. Provides checksumming, fixity checking, OAIS compliance, PREMIS event logging, quarantine management, and comprehensive verification reporting.

Part of the oximedia workspace — a comprehensive pure-Rust media processing framework.

Version: 0.1.7 — 2026-05-16 — 799 tests

Features

Multi-algorithm Checksums — BLAKE3, SHA-256, MD5, and CRC32 verification
Sidecar Files — Generate checksum sidecar files alongside media
Fixity Checking — Scheduled periodic integrity verification
Container Validation — Validate media file structure and metadata
PREMIS Logging — Digital preservation event logging
BagIt Support — BagIt package creation and verification
Quarantine Management — Isolate corrupted or suspect files
SQLite Database — Persistent verification history via sqlx
Parallel Verification — Multi-threaded verification for large archives via rayon
Catalog Management — Archive catalog with search and indexing
Migration Support — Format migration planning and execution
Retention Scheduling — Configurable retention policies
Tape Support — LTO tape archive management
Deduplication — Content-based deduplication

Usage

Add to your Cargo.toml:

[dependencies]
oximedia-archive = "0.1.7"

use oximedia_archive::{ArchiveVerifier, VerificationConfig};
use std::path::Path;

let config = VerificationConfig {
    enable_blake3: true,
    enable_sha256: true,
    generate_sidecars: true,
    ..Default::default()
};

let mut verifier = ArchiveVerifier::with_config(config);
verifier.initialize().await?;

// Verify a file
let result = verifier.verify_file(Path::new("media.mkv")).await?;
println!("Status: {:?}", result.status);
println!("BLAKE3: {:?}", result.checksums.blake3);

// Run scheduled fixity checks
verifier.run_fixity_checks().await?;
