Version: 1.0 Effective Date: January 15, 2026, 09:00 GMT Status: Technical Article - Integration Standards
Framework Integration: ISO/IEC 42001 AI Management System, CEN-CENELEC Harmonized Standards, NIST AI RMF GOVERN Function
This Article establishes comprehensive interoperability standards for AI systems. AI systems do not exist in isolation—they integrate with other systems, share data, and must comply with diverse regulatory frameworks. Interoperability enables ecosystem, compliance, and safety.
Core Principle: Open standards, seamless integration, regulatory harmony.
Representational State Transfer:
Mandatory for All AI Systems with External Interfaces:
Design Principles:
URL Structure: ``` https://api.company.com/v{version}/{resource}/{id}/{action}
Examples: GET /v1/models # List models GET /v1/models/{id} # Get specific model POST /v1/models/{id}/predict # Make prediction GET /v1/models/{id}/metrics # Get performance metrics POST /v1/compliance/verify # Verify compliance ```

Alerting:
Interoperability is the connective tissue of the AI ecosystem. Without standards:
CSOAI interoperability standards enable:
Open standards accelerate safety. When systems can communicate, oversight becomes possible. When data formats are standard, auditing becomes automated. When APIs are consistent, integration becomes seamless.
Interoperability is not just technical—it is enabling infrastructure for global AI governance.
