# WIA-SOC-020: Labor Market Data - Phase 3: Protocol Implementation **Version:** 1.0 **Status:** Active **Last Updated:** 2025-12-26 --- ## 1. Overview Phase 3 of the WIA-SOC-020 Labor Market Data Standard defines Protocol Implementation specifications, enabling seamless integration and interoperability across labor market information systems globally. ### 1.1 Objectives - Establish standardized interfaces for data exchange - Enable real-time data synchronization and updates - Provide secure authentication and authorization mechanisms - Support multiple protocol patterns for diverse use cases - Ensure high performance and scalability ### 1.2 Scope This specification covers technical implementations, security requirements, performance benchmarks, and integration patterns necessary for production deployment. --- ## 2. Technical Specifications ### 2.1 Core Components The Phase 3 architecture includes: - RESTful API endpoints with OpenAPI 3.0 documentation - GraphQL schema for flexible data queries - WebSocket connections for real-time updates - gRPC interfaces for high-performance operations - Event-driven messaging for asynchronous processing ### 2.2 Authentication ``` Authentication Methods: - OAuth 2.0 with PKCE flow - OpenID Connect for identity federation - API keys for service-to-service communication - JWT tokens with RS256 signing - Multi-factor authentication support ``` ### 2.3 Authorization Role-based access control (RBAC) with granular permissions: | Role | Permissions | Use Case | |------|-------------|----------| | Admin | Full read/write access | System administrators | | Analyst | Read access, aggregated statistics | Data analysts, researchers | | Employer | Read/write own job postings | Hiring organizations | | Worker | Read/write own profile | Individual workers | | Public | Read public aggregate data | General public access | --- ## 3. API Endpoints ### 3.1 Worker Profiles ``` GET /api/v1/workers/{workerId} POST /api/v1/workers PUT /api/v1/workers/{workerId} PATCH /api/v1/workers/{workerId} DELETE /api/v1/workers/{workerId} ``` ### 3.2 Employment Data ``` GET /api/v1/employment/{employmentId} GET /api/v1/workers/{workerId}/employment POST /api/v1/employment PUT /api/v1/employment/{employmentId} ``` ### 3.3 Job Postings ``` GET /api/v1/jobs GET /api/v1/jobs/{postingId} POST /api/v1/jobs PUT /api/v1/jobs/{postingId} DELETE /api/v1/jobs/{postingId} Query Parameters: - location: Filter by geographic region - occupation: Filter by occupation code - skills: Filter by required skills - salary_min: Minimum salary - remote: Remote work availability ``` ### 3.4 Labor Market Statistics ``` GET /api/v1/statistics/employment ?region={region}&period={period} GET /api/v1/statistics/wages ?occupation={occupation}®ion={region} GET /api/v1/statistics/skills ?demand=true&trending=true ``` --- ## 4. Security Requirements ### 4.1 Transport Security - TLS 1.3 required for all connections - Certificate pinning for mobile applications - Perfect forward secrecy (PFS) enabled - HSTS headers with long max-age ### 4.2 Data Protection - Encryption at rest: AES-256 - Encryption in transit: TLS 1.3 - Personal data pseudonymization - Differential privacy for aggregate statistics - Secure key management with HSM ### 4.3 Access Control - IP whitelisting for sensitive operations - Rate limiting: 1000 requests/minute per client - DDoS protection and traffic filtering - Audit logging for all data access - Automated threat detection --- ## 5. Performance Requirements ### 5.1 Response Times | Operation | Target | Maximum | |-----------|--------|---------| | Simple GET | <100ms | 250ms | | Complex query | <500ms | 1000ms | | POST/PUT | <200ms | 500ms | | Batch operations | <2s | 5s | ### 5.2 Throughput - Minimum: 10,000 requests/second - Target: 50,000 requests/second - Peak capacity: 100,000 requests/second ### 5.3 Availability - Uptime SLA: 99.9% (8.76 hours downtime/year) - Planned maintenance windows: <4 hours/month - Disaster recovery RTO: <4 hours - Disaster recovery RPO: <1 hour --- ## 6. Error Handling ### 6.1 HTTP Status Codes ``` 200 OK - Successful request 201 Created - Resource created successfully 204 No Content - Successful deletion 400 Bad Request - Invalid input 401 Unauthorized - Authentication required 403 Forbidden - Insufficient permissions 404 Not Found - Resource doesn't exist 429 Too Many Requests - Rate limit exceeded 500 Internal Server Error - Server error 503 Service Unavailable - Temporary unavailability ``` ### 6.2 Error Response Format ```json { "error": { "code": "INVALID_OCCUPATION_CODE", "message": "The occupation code 'SOC-99-9999' is not valid", "details": { "field": "occupationCode", "value": "SOC-99-9999", "validFormat": "SOC-XX-XXXX" }, "timestamp": "2025-12-26T10:30:00Z", "requestId": "req-123456" } } ``` --- ## 7. Integration Patterns ### 7.1 Real-Time Streaming WebSocket connection for live updates: ```javascript const ws = new WebSocket('wss://api.wiastandards.com/labor-market/stream'); ws.onmessage = (event) => { const update = JSON.parse(event.data); console.log('New job posting:', update); }; ``` ### 7.2 GraphQL Queries ```graphql query LaborMarketInsights { region(code: "US-CA") { employment { rate trend } topOccupations(limit: 10) { code title demand medianWage } skillsInDemand { skillId name demandIndex } } } ``` --- ## 8. WIA Ecosystem Integration ### 8.1 Connected Standards - **WIA-EDU**: Educational credential verification - **WIA-CREDENTIAL**: Verifiable employment credentials - **WIA-SOCIAL**: Social services coordination - **WIA-MIGRATION**: Cross-border mobility data - **WIA-AI**: AI-powered workforce analytics ### 8.2 Cross-Standard Data Flow ``` Worker completes WIA-EDU certification ↓ Credential recorded in WIA-CREDENTIAL ↓ Skill added to WIA-SOC-020 worker profile ↓ Matched to job postings automatically ↓ Employment data feeds WIA-SOCIAL programs ``` --- ## 9. Compliance Checklist Organizations implementing Phase 3 must: - ✅ Implement all required API endpoints - ✅ Meet security and encryption standards - ✅ Achieve performance benchmarks - ✅ Provide comprehensive API documentation - ✅ Support real-time data streaming - ✅ Pass interoperability testing - ✅ Maintain 99.9% uptime SLA --- **弘益人間 (Benefit All Humanity)** © 2025 WIA - World Certification Industry Association | MIT License
