OTML is an object tree model language. It is a language that describes a tree of objects, which is easily readable by both man and machine. It is abstract, flexible and simple. There is no data standardization and no arrays in it. OTML supports comments and stream processing.

OTML targets

• To be easily understandable to a man
• To be minimalistic: have a syntax consisting of a minimum set of rules
• To be as abstract and flexible as possible, allowing to describe as many different data structures as possible
• To support data stream processing
• To develop and change easily, have a versioning system
• Forget about it: {}, this: [] and this: ()

OTML example:

@FooObject
	TestId : 252
	Amount : 226
	Comments : 
		string129
		string93
		string190
	Date : "2020-03-29T16:04:35.4042938"
	StatusId : 253
	IsReadOnly : False

	Code : Codestring48
	Values :

	MultilineStringValue : 
		"When an outburst occurs from gas very near the black hole," +
		"the ejected gas collides with material flowing away from the massive stars in winds," +
		"pushing this material backwards and causing it to glow in X-rays." +
		"When the outburst dies down the winds return to normal and the X-rays fade."

Serialization

The next class will be used in examples:

public class Foo
{
	public string Name { get; set; }
	public string StringValue { get; set; }
	public int IntValue { get; set; }
}

Serialization to string:

var fooClass = new Foo
{
	Name = "Name",
	StringValue =  "Value",
	IntValue = 123
};

var serializer = OtmlSerializer.Create();

string result = serializer.Serialize(fooClass);

Serialization to Stream:

var fooClass = new Foo
{
	Name = "Name",
	StringValue =  "Value",
	IntValue = 123
};

var serializer = OtmlSerializer.Create();

using (var stream = File.OpenWrite("C:\\result.otml"))
{
	serializer.Serialize(fooClass, stream);
}

Deserialization

Deserialization from string:

var serializer = OtmlSerializer.Create();

var source =
	"@Foo\n" +
	"\tName: Name\n" +
	"\tStringValue : Value\n" +
	"\tIntValue : 123";

Foo result = serializer.Deserialize<Foo>(source);

Deserialization from Stream:

var source =
	"@Foo\n" +
	"\tName: Name\n" +
	"\tStringValue : Value\n" +
	"\tIntValue : 123";

using (var stream = new MemoryStream(Encoding.UTF8.GetBytes(source)))
{
	Foo result = serializer.Deserialize<Foo>(stream);
}
