📢 Sovereign Node Notice (16 Feb 2026)

To the 210+ Sovereign Nodes currently running ODGS (v3.0.0)

We have observed a significant spike in "Blind Clones" (direct CI/CD deployments) adhering to the EU AI Act (Article 10) requirements. We recognize that many of you are operating inside strict corporate firewalls (Banking/Gov/Logistics) and cannot interact publicly.

We respect your sovereignty and do not track you.

However, because this protocol enforces Administrative Recusal (Hard Stops), a Semantic Definition update can halt your production pipelines.

⚠️ OPERATIONAL ADVISORY: To prevent "Definition Drift" in your critical paths, please click the Watch button (top right) $\rightarrow$ select Releases Only.

• This ensures your Engineering Leads receive an immediate notification if a Schema Breaking Change is merged.
• This is the only channel we will use to broadcast critical compliance patches.

ODGS: Open Data Governance Standard

The Runtime Enforcement Standard for EU AI Act Article 10 & 12.

---

1. The Standard

The Open Data Governance Standard (ODGS) is a vendor-neutral protocol for Sovereign Data Governance. It resolves the "Definition-Execution Gap" in High-Risk AI Systems by creating a deterministic method for Administrative Recusal.

"Silence over Error." — The Core Philosophy. If the semantic definition of data drifts from its legal meaning, the system must execute a Hard Stop rather than process an invalid inference.

This repository contains the Reference Implementation (v3.0.0), demonstrating how to strictly decouple "The Law" (Legislative Plane) from "The Machine" (Physical Plane).

---

2. Regulatory Alignment

This standard is architected to satisfy the "Error-Free Data" and "Automatic Recording" mandates of the Digital State:

• 🇪🇺 EU AI Act (2024/1689)
  • Article 10: Validation of data provenance and semantic integrity.
  • Article 12: Generation of immutable, forensically sound event logs.
• 🇳🇱 NEN 381 525 (Data & Cloud)
  • Sovereignty: Ensures data processing logic remains portable and vendor-independent.
• 🌐 ISO/IEC 42001 (AI Management)
  • Control B.9: Operational control of AI systems via runtime enforcement.

3. The 5-Plane Architecture

ODGS implements a "Constitutional Stack" where mechanical execution is legally bound by semantic definitions.

4. Technical Implementation: A Polyglot Protocol

The Open Data Governance Standard is Language Agnostic. It defines the "What" (JSON Schemas), allowing the "How" (Interceptor) to be implemented in any language.

Core Privacy Feature: Git-as-Backend

• Sovereign Logger: A privacy-native audit engine that commits signed evidence directly to your private Git repository. You retain 100% custody of all your data as well as the forensic evidence.

This Reference Implementation provides a Dual-Stack approach:

1. Python (The Data Plane)

• Role: Heavy-duty Data Engineering, Airflow/dbt integration, and Runtime Enforcement.
• Location: src/odgs/executive/interceptor.py
• Install: pip install odgs

2. Node.js (The Developer Experience)

• Role: CLI tools, VS Code integrations, and Frontend Visualizers.
• Location: lib/
• Install: npm install odgs

---

Quick Start

1. Initialize a Sovereign Project

# Python
pip install odgs
odgs init my-project

# Node.js
npm install -g odgs
odgs init my-project

2. Define a Metric (The Law)

odgs add metric "Gross_Revenue" --definition "Sum(invoices) - VAT"

3. Run the Interceptor Start the API server to enforce rules on incoming data payloads.

odgs api --port 8000

5. Documentation & Contribution

This is a Coalition of the Willing. We invite Legal Scholars and Public Administrators to contribute to the Standard definitions.

• Technical Annex (Sovereignty): Detailed explanation of the "Sovereign Sidecar" pattern.
• Governance Manifesto: Principles of Regulatory Consensus.

• No Vendor Lock-in.
• No Cloud Dependency.
• 100% Data Sovereignty.
