8.1 WIA-PET-009 Certification Levels
The WIA-PET-009 standard defines three certification tiers, enabling organizations to demonstrate compliance appropriate to their role in the pet nutrition ecosystem.
+----------+------------------------+-------------------------------------------+ | Level | Requirements | Ideal For | +----------+------------------------+-------------------------------------------+ | Level 1 | - Data Format | - Pet food manufacturers | | Basic | Compliance | - Product databases | | | - JSON schema | - Simple tracking apps | | | validation | - Start-ups/MVPs | | | - Core entities only | | +----------+------------------------+-------------------------------------------+ | Level 2 | - Level 1 PLUS | - Veterinary clinics | | Advanced | - API implementation | - Diet planning apps | | | - Authentication | - Allergy management systems | | | - Extended entities | - Weight management platforms | | | - Allergy tracking | | +----------+------------------------+-------------------------------------------+ | Level 3 | - Level 2 PLUS | - Smart feeder manufacturers | | Full | - Real-time sync | - Comprehensive nutrition platforms | | | - IoT device | - Veterinary management systems | | | integration | - Enterprise solutions | | | - Security audit | | | | - Vet system | | | | interoperability | | +----------+------------------------+-------------------------------------------+
8.2 Certification Process
8.2.1 Application and Documentation
Step 1: Pre-Certification Assessment (Self-Service)
- Review WIA-PET-009 specification documents (Phases 1-4)
- Complete self-assessment checklist for target certification level
- Identify implementation gaps and remediation timeline
Step 2: Formal Application
- Submit online application via WIA portal (wia.org/pet-nutrition/certification)
- Specify certification level (1, 2, or 3)
- Provide organization details, technical contact, implementation scope
- Pay certification fee (sliding scale based on organization size and level)
Step 3: Documentation Submission
- API documentation (if Level 2/3): OpenAPI/Swagger specification
- Data model schemas: JSON Schema files for all implemented entities
- Security architecture (if Level 3): Encryption methods, authentication flows, access controls
- Test plan: Comprehensive test cases covering all requirements
- Sample data: Anonymized examples demonstrating each entity and use case
8.2.2 Technical Validation
Automated Testing (Level 1)
- JSON schema validation against official WIA-PET-009 schemas
- Data type verification
- Required field presence
- Format validation (dates, IDs, units)
API Testing (Level 2/3)
- Endpoint availability and response times
- Authentication and authorization mechanisms
- Rate limiting compliance
- Error handling and status codes
- Data consistency across create/read/update/delete operations
Integration Testing (Level 3)
- End-to-end workflow testing with reference implementations
- IoT device communication protocols
- Real-time data synchronization
- Multi-system interoperability scenarios
8.2.3 Security Audit (Level 3 Only)
Level 3 certification requires independent security assessment:
- Penetration Testing: Simulated attacks to identify vulnerabilities
- Data Privacy Review: GDPR-equivalent compliance for pet health data
- Encryption Verification: TLS 1.3+ for transport, AES-256 for storage
- Access Control Testing: Role-based permissions, owner consent flows
- Incident Response Plan: Data breach notification procedures

- MINOR (1.1.x → 1.2.x): New features, backwards compatible
- PATCH (1.1.1 → 1.1.2): Bug fixes, fully compatible
API Versioning Strategy:
- URL-based versioning: /api/v1/, /api/v2/
- Support N-1 version for 24 months post-new version release
- Deprecation warnings in API responses 12 months before sunset
- Migration guides provided for major version upgrades
