Totum Universal File Format Library

A comprehensive .NET Standard 2.0 / 2.1 library for working with Totum Universal File Format (.totum) archives.

What is Totum?

Totum is a ZIP-based archive format with a JSON manifest that provides:

Structured metadata via manifest.json
Version-aware reading and writing
Extensible through JSON ExtensionData
Forward-compatible design
Dual JSON support (System.Text.Json and Newtonsoft.Json)

Quick Start

Installation

# Meta-package with all common dependencies
dotnet add package Totum.Universal

# Or install specific packages
dotnet add package Totum.Universal.Core
dotnet add package Totum.Universal.Json.SystemTextJson

Basic Usage

using Totum.Universal.Abstractions;
using Totum.Universal.Core;
using Totum.Universal.Json.SystemTextJson;

// Set up services
var jsonSerializer = new SystemTextJsonSerializer();
var archiveWriter = new TotumArchiveWriter(jsonSerializer);

// Create a manifest
var manifest = new Manifest
{
    Version = "1.0",
    Created = DateTime.UtcNow,
    Title = "My Archive"
};

manifest.Files.Add(new FileDescriptor 
{ 
    Path = "data.txt", 
    Type = "text/plain" 
});

// Write archive
await archiveWriter.WriteAsync("output.totum", manifest, files);

With Dependency Injection

services.AddTotumUniversal(); // Uses System.Text.Json by default
// or
services.AddTotumUniversalWithNewtonsoft(); // Uses Newtonsoft.Json

Features

✅ Version-aware - Automatic compatibility checks
✅ Validation - Comprehensive manifest validation with 3 modes
✅ Extensibility - ExtensionData for custom fields
✅ Async/await - Full async support throughout
✅ DI-ready - Built-in dependency injection support
✅ Well-tested - 100+ unit tests with 100% pass rate
✅ .NET Standard 2.0 / 2.1 - Compatible with .NET Framework, .NET Core, .NET 5+
