Odin.Core

Official .NET SDK for ODIN (Open Data Interchange Notation) — a canonical data model for transporting meaning between systems, standards, and AI.

Install

dotnet add package Odin.Core

Targets: netstandard2.0, net8.0

Quick Start

using Odin.Core;

var doc = Odin.Parse(@"
{policy}
number = ""PAP-2024-001""
effective = 2024-06-01
premium = #$747.50
active = ?true
");

Console.WriteLine(doc.Get("policy.number")); // "PAP-2024-001"
Console.WriteLine(doc.Get("policy.premium")); // 747.50

var text = Odin.Stringify(doc);

Core API

Method	Description	Example
`Odin.Parse(text)`	Parse ODIN text into a document	`var doc = Odin.Parse(src);`
`Odin.Stringify(doc)`	Serialize document to ODIN text	`var text = Odin.Stringify(doc);`
`Odin.Canonicalize(doc)`	Deterministic bytes for hashing/signatures	`var bytes = Odin.Canonicalize(doc);`
`Odin.Validate(doc, schema)`	Validate against an ODIN schema	`var result = Odin.Validate(doc, schema);`
`Odin.ParseSchema(text)`	Parse a schema definition	`var schema = Odin.ParseSchema(src);`
`Odin.Diff(a, b)`	Structured diff between two documents	`var changes = Odin.Diff(docA, docB);`
`Odin.Patch(doc, diff)`	Apply a diff to a document	`var updated = Odin.Patch(doc, changes);`
`Odin.ParseTransform(text)`	Parse a transform specification	`var tx = Odin.ParseTransform(src);`
`Odin.ExecuteTransform(tx, source)`	Run a transform on data	`var result = Odin.ExecuteTransform(tx, doc);`
`doc.ToJson()`	Export to JSON	`var json = doc.ToJson();`
`doc.ToXml()`	Export to XML	`var xml = doc.ToXml();`
`doc.ToCsv()`	Export to CSV	`var csv = doc.ToCsv();`
`Odin.Stringify(doc)`	Export to ODIN	`var odin = Odin.Stringify(doc);`
`Odin.Builder()`	Fluent document builder	`Odin.Builder().Section("policy")...`
`Odin.CreateStreamingParser(handler)`	Streaming/SAX-style parser	`Odin.CreateStreamingParser(handler);`

Schema Validation

using Odin.Core;

var schema = Odin.ParseSchema(@"
{policy}
!number : string
!effective : date
!premium : currency
active : boolean
");

var doc = Odin.Parse(source);
var result = Odin.Validate(doc, schema);

if (!result.Valid)
{
    foreach (var error in result.Errors)
        Console.WriteLine(error);
}

Transforms

using Odin.Core;

var transform = Odin.ParseTransform(@"
map policy -> record
  policy.number -> record.id
  policy.premium -> record.amount
");

var result = Odin.ExecuteTransform(transform, doc);

Export

var odin = Odin.Stringify(doc); // ODIN string
var json = doc.ToJson();       // JSON string
var xml  = doc.ToXml();        // XML string
var csv  = doc.ToCsv();        // CSV string

Builder

var doc = Odin.Builder()
    .Section("policy")
    .Set("number", "PAP-2024-001")
    .Set("effective", new DateOnly(2024, 6, 1))
    .Set("premium", new OdinCurrency(747.50m))
    .Set("active", true)
    .Build();

Streaming Parser

Odin.CreateStreamingParser(new OdinStreamHandler
{
    OnSectionStart = name => Console.WriteLine($"Section: {name}"),
    OnField = (key, value) => Console.WriteLine($"{key} = {value}"),
    OnSectionEnd = name => { }
});
