Open Data Governance Standard (ODGS)

The Universal Validation Engine for High-Risk Data.

---

Important

EU AI Act & CEN-CENELEC JTC 25 Candidate Standard (v5.2.0 Update) ODGS has been upgraded to a strict Polymorphic Execution Engine. It seamlessly evaluates your standard operational telemetry while natively ingesting authoritative W3C/JSON-LD legal ontologies (e.g., TNO FLINT) to enforce Administrative Recusal ("Hard Stop") in High-Risk AI pipelines.

🚀 What's New in v5.2.0: Minimalist Tier & Deployment Telemetry

v5.2.0 upgrades the ODGS initialization and runtime engine to support rapidly-scaling teams.

• Minimalist Execution: Initialize core Metric & Rule files via odgs init --tier minimalist without forcing complex ontology graphs or physical maps. Validations gracefully adapt to missing unrequired schemas.
• Deployment Status Telemetry: The CLI validation output and audit logs now surface the deployment's certification status, giving teams clear visibility into whether their active rule packs are cryptographically signed or running as standard local deployments.
• Dynamic Version Mapping: The CLI version and init commands dynamically extract the installed package version to ensure uniform synchronization across the standard.

🏢 Enterprise & Public Sector: EU AI Act Compliance

This open-source package connects your physical data infrastructure to the ODGS validation engine. However, if you are operating a High-Risk AI System and require strict liability indemnification under the EU AI Act (Articles 10 & 12), you need cryptographic provenance.

Metric Provenance offers the commercial Enterprise Infrastructure for ODGS:

• Certified Sovereign Packs: Pre-compiled, cryptographically signed Ed25519 rule bundles for DORA, EU AI Act, and Basel.
• The S-Cert Sovereign Registry: An air-gapped Enterprise Certificate Authority that natively ingests ODGS telemetry to mint immutable, JWS-sealed audit logs.

1. The Standard: Data Governance Without Compromise

The Open Data Governance Standard (ODGS) resolves the "Definition-Execution Gap" in data pipelines.

"Silence over Error." — The Core Philosophy. If data drifts from its legal, contractual, or internal definition, the pipeline must mathematically halt rather than process an invalid inference.

Semantic Certificate — Every sovereign definition carries a cryptographic fingerprint bound to its issuing authority. The data equivalent of a TLS certificate.

📊 More Screenshots — Compliance Matrix · Sovereign Brake

Sovereign Compliance Matrix — Real-time governance status across 72 business metrics, aligned with EU AI Act Art. 10 & 12.

Sovereign Brake — Live Interceptor — When data does not match its statutory definition, the system refuses to proceed. This is the "Administrative Recusal" principle.

2. Quick Start: The Data Engineer Workflow

Stop relying on passive analytics dashboards. Enforce statutory rules directly in your Python transforms.

Install

pip install odgs

Create a Governance Project

# Standard 5-Plane Topology
odgs init MyProject

# Minimalist Topology (Fast Start for small teams)
odgs init MyProject --tier minimalist

Example: Halting a Pipeline in Python/dbt

Inject ODGS directly into your data warehouse transforms, Airflow DAGs, or Databricks PySpark wrappers:

from odgs.executive.interceptor import OdgsInterceptor
from odgs.executive.exceptions import AdministrativeRecusal

engine = OdgsInterceptor()

# The physical payload (e.g., an AI applicant profile or standard telemetry)
payload = {"transaction_value": 150000, "aml_flag": False}

try:
    # Evaluate against your internal checks or mathematically hashed W3C JSON-LD ontologies
    engine.intercept("urn:odgs:sov:eu-ai-act:aml-threshold", payload)
    print("Payload Validated. Proceeding to inference.")
    
except AdministrativeRecusal as e:
    # The pipeline HALTS before an illegal decision is made.
    print(f"HARD STOP EXECUTED: Data Drift Detected. {e}")

3. The 5-Plane Semantic Architecture (v5)

ODGS v5 implements a strict 5-Plane topology to guarantee the absolute sovereignty of legislative intent over physical execution pipelines.

graph TD
    subgraph Legislative_Plane ["I. Legislative Plane (Semantic Truth)"]
        FLINT[TNO FLINT / W3C JSON-LD] --> |Semantic Hash| Definition(Statutory Definition)
    end
    
    subgraph Physical_Plane ["II. Physical Plane (ODGS Execution Engine)"]
        Definition -.-> |Cryptographic Tether| Boundary[Execution Boundary]
        Boundary --> Eval{Constraint Evaluation}
        
        Pipeline[IV. Data Pipeline Plane] --> |Payload| Eval
        
        Eval --> |Compliant| Approved[Execution Authorized]
        Eval --> |Data Drift Detected| Recusal[Administrative Recusal]
        
        Approved --> Audit[V. Forensic Audit Plane]
        Recusal --> Audit
        
        Audit --> |Generates| SCert[S-Cert: Immutable JWS Provenance Log]
    end

4. Platform Bridges

ODGS bridges connect your existing data governance platform to the Execution Engine, transforming passive data dictionaries into active runtime enforcement.

Bridge	Function	Status
odgs-flint-bridge	Legislative: Ingests TNO FLINT JSON-LD into ODGS schema.
odgs-collibra-bridge	Physical: Collibra Business Glossary integration.
odgs-databricks-bridge	Physical: Databricks Unity Catalog integration.
odgs-snowflake-bridge	Physical: Snowflake Data Dictionary integration.

5. Air-Gapped Execution & Stateless Cryptography (JWKS)

The ODGS Engine operates with Zero Telemetry and does not "phone home". It is designed for strict air-gapped enterprise environments.

To ensure metric authenticity, ODGS implements stateless cryptography using standard Ed25519 JWKS (JSON Web Key Set) public keys. When the Engine loads a Sovereign Pack, it cryptographically verifies the signature against the cached JWKS public key.

---

6. Audit Ledgers: Cryptographic Verifiability & Zero-Knowledge

ODGS outputs an agnostic cryptographic_attestation JSON schema to satisfy EU AI Act Article 12 (Forensic Logging) without exposing third-party data.

• Git-as-Backend: ODGS utilizes a privacy-native logging architecture. Forensic logs are written directly to your private enterprise Git repository. Zero data ever leaves your perimeter.
• The Tri-Partite Hash: The engine generates a cryptographic proof binding the Input Data Hash + Rule Definition Hash + Engine Configuration Hash. Independent auditors and regulatory bodies can mechanically verify the integrity of algorithmic decisions without exposing PII.

---

7. Enterprise Deployment (Kubernetes / Helm)

For organization-wide policy enforcement, Sovereign Nodes can deploy ODGS as an active sidecar container routing mesh traffic.

# Add the Official Metric Provenance Repository
helm repo add metricprovenance https://charts.metricprovenance.com
helm repo update

# Install the Engine
helm install odgs-cluster-agent metricprovenance/odgs-engine \
  --set configuration.namespace="urn:odgs:sov" \
  --set keys.jwks_url="https://platform.metricprovenance.com/.well-known/jwks.json"
