Datamodel.NET is a library which implements the Datamodel structure and Datamodel Exchange (DMX) file format.

Datamodel is a strongly-typed generic data structure designed by Valve Corporation. It is primarily used as a developer storage format for meshes, animations, and maps.

Usage

dotnet add package KeyValues2

using Datamodel;

// Load a file with unknown layout
using var dm = Datamodel.Load("my_file.dmx");
var element = dm.Root;
var value = element.Get<string>("my_property");

// Load a file with a known layout
using var map = Datamodel.Load<CMapRootElement>("fy_pool.vmap");
var root = (CMapRootElement)map.Root;
Debug.Assert(root.IsPrefab == false);

// Layout definition
// Full implementation can be found here:
// https://github.com/ValveResourceFormat/Datamodel.NET/blob/master/Tests/ValveMap.cs
[LowercaseProperties]
class CMapRootElement : Element
{
    public bool IsPrefab { get; set; }
    public int EditorBuild { get; set; } = 8600;
    public int EditorVersion { get; set; } = 400;
}

Features

• Support for all known versions of Valve's binary and keyvalues2 DMX encodings
• Inline documentation
• Binary codec supports just-in-time attribute loading
• Write your own codecs with the ICodec interface
• Serialize and deserialize support for Datamodel.Element subclasses

Serialization

var HelloWorld = new Datamodel.Datamodel("helloworld", 1); // must provide a format name (can be anything) and version

HelloWorld.Root = new Datamodel.Element(HelloWorld, "my_root");
HelloWorld.Root["Hello"] = "World"; // any supported attribute type can be assigned

var MyString = HelloWorld.Root.Get<string>("Hello");

HelloWorld.Save("hello world.dmx", "keyvalues2", 1); // must provide an encoding name and version

<--! dmx encoding keyvalues2 1 format helloworld 1>
{
    "Hello" "string" "World"
}

Attributes

The following .NET types are supported as Datamodel attributes:

• int
• float
• bool
• string
• byte
• byte[]
• Vector2
• Vector3
• Vector4 / Quaternion
• Matrix4x4
• ulong
• System.TimeSpan

Additionally, the following Datamodel.NET types are supported:

• Element (a named collection of attributes)
• QAngle

IList<T> collections of the above types are also supported. (This can be a bit confusing given that both byte and byte[] are valid attribute types; use the ByteArray type if you run into trouble.)
