The High-Density, Token-Efficient Data Protocol for Large Language Models. Stop wasting context window on JSON braces. AI.DATA is a unified, schema-first data format designed specifically for AI understanding. It offers up to 25% token savings, faster parsing, and human-readable structure that LLMs love.

---

📦 Installation

Get started immediately with pip:

pip install arkadia-ai-data-format

🚀 Fast Example

Encoding to AI.DATA:

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

Decoding back to JSON:

echo '<data:number>(2)' | aid dec - -f json
# Output: { "data": 2 }

⚡ Performance & Token Savings

Why switch? Because every token counts. AICD (Arkadia Compressed Data) consistently outperforms standard formats in both token efficiency.

📖 Syntax Specification (Current Version)

This section describes the actual, currently implemented syntax of AI.DATA-FORMAT.

1. Type Definition

A type defines a name and an ordered list of fields. Comments are allowed within the definition to assist the LLM.

User</comment/ ={(23,"A",3) #tag1 #tag2} %[{ id: 4, b: "a", c: 43}]: id:number,
b: string , c:number, >
@Users
<
 @list 
 a: number,
 b: string
>
[
  @size=5
  /example list of values/

  (1,`text`,5)
  (2,`Text can be

multiline
`,5)
  {
    id:3,
    b: "text"
  }
]

Key Rules:

• The type name (@Name) is optional but recommended.
• The header <...> defines field names and their order.
• Comments (/ ... /) are allowed in the header.

2. Data Structures

The format supports compact positional records and explicit named records.

Structure	Syntax	Description
Positional Record	(a,b,c)	Must follow the exact order of fields in the type header.
Named Record	{key:value}	Keys must match field names. No spaces allowed in keys/values.
List	[ ... ]	Contains positional or named records.
Multiline Text	text	Ends with a line containing only a backtick.

3. Comments

/ this is a comment /

• Allowed only inside type definitions.
• Forbidden in raw data blocks to save space.

4. General Rules

1. Data must contain NO spaces. (Compactness is priority).
2. Schema/Type definitions may contain spaces and comments.
3. Named fields always use key:value without spaces.
4. Positional order must exactly match the declared order.

5. Inline Type Usage

You can declare a type and immediately use it:

@User<id:number name:string desc:string>

value:@User(2,"Alice","Hello")
value2:@User(3,"Bob","World")

6. Nested Types

Currently, nested types are allowed as structural definitions:

@User<
  id:string
  name:string
  profile: < level:number, score:number >
>
[
  ("u1","Aga",{level:5,score:82})
  ("u2","Marek",{level:7,score:91})
]

---

🔮 Futures / Roadmap

The following features are planned for future releases and are not yet implemented.

• Modifiers:

• !required - field must be included.

• ?empty - field must not be empty.

• =value - default value.

• N..M - numeric range validation.

• Binary Data Types:

• Hex: ~[hex]1A0F4F~

• Base64: ~[b64]ADFKDXKZK...~

• Pointers/References:

• Reference existing objects by ID: (1, "Alex", *User[2])
