The High-Density, Token-Efficient Data Protocol for Large Language Models.

Arkadia Data Format (AKD) is a schema-first protocol designed specifically to optimize communication with LLMs. By stripping away redundant syntax (like repeated JSON keys) and enforcing strict typing, AKD offers up to 30% token savings, faster parsing, and a metadata layer invisible to your application logic but fully accessible to AI models.

This Python package includes the full core library and the akd CLI tool.

✨ Key Features

• 📉 Token Efficiency: Reduces context window usage by replacing verbose JSON objects with dense Positional Records (Tuples).
• 🛡️ Type Safety: Enforces types (int, float, bool, string) explicitly in the schema before data reaches the LLM.
• 🧠 Metadata Injection: Use #tags and $attributes to pass context (e.g., source confidence, deprecation warnings) to the LLM without polluting your data structure.
• 🖥️ Powerful CLI: Includes the akd terminal tool for encoding, decoding, and benchmarking files or streams.
• ⚡ Zero Dependencies: Pure Python implementation, lightweight and fast.

📦 Installation

Install directly from PyPI:

pip install arkadia-data

---

🚀 Quick Start (Library)

Basic Usage

import arkadia.data as akd

# 1. Encode: Python Dict -> AKD String
data = { "id": 1, "name": "Alice", "active": True }
encoded = akd.encode(data)

print(encoded)
# Output: <id:number,name:string,active:bool>(1,"Alice",true)


# 2. Decode: AKD String -> Python Dict
input_str = '<score:number>(98.5)'
result = akd.decode(input_str)

if not result.errors:
    print(result.node.value) # 98.5
else:
    print("Errors:", result.errors)

---

🛠 CLI Usage

The Python package installs the akd (alias: ak-data) command globally.

USAGE:
   akd / ak-data <command> [flags]

COMMANDS:
   enc             [ENCODE] Convert JSON/YAML to AK Data format
   dec             [DECODE] Parse AK Data format back to JSON
   benchmark       [BENCHMARK] Run performance and token usage tests

Examples

1. Pipe JSON to AKD (Compact Mode):

echo '{ "data": 2}' | akd enc - -c
# Output: <data:number>(2)

2. Decode AKD file to JSON:

akd dec payload.akd -f json

3. Run Benchmarks on a directory:

akd benchmark ./data_samples

---

⚡ Benchmarks

Why switch? Because every token counts. AKCD (Arkadia Compressed Data) consistently outperforms standard formats.

BENCHMARK SUMMARY:

   JSON  █████████████████████░░░░     6921 tok     0.15 ms
   AKCD  ████████████████░░░░░░░░░     5416 tok     4.40 ms
   AKD   ███████████████████░░░░░░     6488 tok     4.29 ms
   TOON  █████████████████████████     8198 tok     2.36 ms

   FORMAT     TOKENS       VS JSON
   ---------------------------------
   AKCD       5416         -21.7%
   AKD        6488         -6.3%
   JSON       6921         +0.0%
   TOON       8198         +18.5%

CONCLUSION: Switching to AKCD saves 1505 tokens (21.7%) compared to JSON.

📖 Syntax Specification

AKD separates structure (Schema) from content (Data).

1. Primitives

Primitive values are automatically typed. Strings are quoted, numbers and booleans are bare.

Type	Input	Encoded Output
Integer	123	<number>123
String	"hello"	<string>"hello"
Boolean	true	<bool>true
Null	null	<null>null

2. Schema Definition (@Type)

Define the structure once to avoid repeating keys.

/* Define a User type */
@User <
  id: number, 
  name: string, 
  role: string 
>

3. Data Structures

Positional Records (Tuples)

The most efficient way to represent objects. Values must match the schema order.

/* Schema: <x:number, y:number> */
(10, 20)

Named Records (Objects)

Flexible key-value pairs, similar to JSON, used when schema is loose or data is sparse.

{
  id: 1,
  name: "Admin"
}

Lists

Dense arrays. Can be homogenous (list of strings) or mixed.

[ "active", "pending", "closed" ]

4. Metadata System

AKD allows you to inject metadata that is visible to the LLM but ignored by the parser when decoding back to your application.

Attributes ($key=value) & Tags (#flag)

@Product <
  $version="2.0"
  sku: string,
  
  /* Tagging a field as deprecated */
  #deprecated
  legacy_id: int
>
