Anumati Project

Ownership & Information Flow Primitives for DPIs

Anumati Project is a reference implementation of Digital Public Infrastructure (DPI) primitives enabling legitimate, governed, transparent, and purpose-bound data sharing.
It provides a Locker-based architecture, Connection Types, Terms, and X-Node Structure for Maintaing the Flow Control for Transfer of Ownership

✨ Core Features

1. User Management

Sign Up

Endpoint: /signup-user (form-data)
Example:

• username: iiitb
• description: Deemed University
• password: iiitb

Login

Endpoint: /login-user (form-data)

---

2. Locker Management

Users can create multiple lockers.
Lockers organize user resources (documents, files, certificates).

API: /create-locker
Example form-data:

name: Education
description: Education records locker

---

3. Resource Sharing via Connections

Connections link two lockers (host ↔ guest).

API: /create-new-connection
Example form-data:

connection_name: Connection No.1
connection_type_name: MTech 2024 Admissions
guest_username: Rohith
guest_lockername: Education
host_username: iiitb
host_lockername: Admissions

---

4. Connection Types

Define:

• Obligations
• Permissions
• Rules
• Validity
• Purpose of sharing

API: /create-connection-type-and-terms
Example JSON:

{
  "connectionName": "Alumni Networks",
  "connectionDescription": "Connection type for alumni communication.",
  "lockerName": "Transcripts",
  "obligations": [{
      "labelName": "Graduation Batch",
      "typeOfAction": "Add Value",
      "typeOfSharing": "Share",
      "labelDescription": "Mandatory to enter graduation batch",
      "hostPermissions": ["Re-share", "Download"]
  }],
  "permissions": {
      "canShareMoreData": true,
      "canDownloadData": false
  },
  "validity": "2024-12-31"
}

---

5. Admin Functions

• Freeze lockers
• Manage global connections
• Control connection types and terms

📘 Workflow Overview

Step 1 — Create Connection Type

Defines:

• Purpose
• Terms
• Obligations
• Permissions
• Validity

Step 2 — Create Lockers

Users create lockers to store their documents/resources.

Step 3 — Create Connection

Connect host ↔ guest lockers using a connection type.

Step 4 — Enforce Terms

System enforces:

• Obligations
• Permissions
• Validity rules
• Sharing restrictions

---

📜 Project Goals

• Standardized primitives for legitimate data sharing
• User-controlled data governance
• Transparent & auditable access
• DPI-aligned design (similar to UPI but for data)
• Scalable for cross-border consented sharing

---

🛠 Tech Stack

Backend

• Python
• Django 5.x
• Django REST Framework
• SQLite

Frontend

• React
• Node.js
• HTML/CSS/JS
