PLAN: BOOST Relationship System Consolidation Enhancement (DEFERRED)

[pwt-cd]

BOOST Relationship System Consolidation Enhancement Plan

Executive Summary

The BOOST data standard currently maintains entity relationships in two separate, parallel systems that create critical architectural risks and maintenance burden. This enhancement plan addresses the consolidation of schema metadata relationships and ERD navigator configuration into a unified, schema-first approach.

Current Conformance Assessment

Architecture Consistency Score: 3/10

• Critical Gap: Dual relationship definition systems with divergent formats
• Maintenance Burden: Every relationship change requires updates in two locations
• Data Integrity Risk: Schema validation and ERD visualization may show different relationships

Enhancement Target: 10/10 - Single source of truth with automated ERD generation

Strategic Rationale

Drawing on comprehensive system analysis, the dual relationship system represents a fundamental architecture debt that impacts development velocity, system reliability, and data integrity. The proposed schema-first consolidation approach eliminates these risks while preserving existing ERD visualization capabilities and establishing a foundation for enhanced automation.

Current System Analysis

Dual System Architecture Issues

1. Relationship Definition Locations

• Schema Metadata: 35 entity schemas contain boost_metadata.relationships arrays
• ERD Configuration: Manual manual_relationships array with 134+ relationship definitions in erd-config.json
• Critical Risk: Systems can diverge, creating inconsistent relationship models

2. Format Inconsistencies

Stakeholder analysis reveals significant maintenance challenges:

• Schema metadata: "label": "headquartered at"
• ERD config: "label": "headquartered_at"
• Cardinality differences: "many-to-one" vs "from_cardinality": "many"

3. System Comparison Matrix

Table 1. Current Dual Relationship System Comparison

Aspect	Schema Metadata	ERD Configuration
Location	Distributed across entity schemas	Centralized in erd-config.json
Structure	Simple field→entity mapping	Full bidirectional relationship specs
Purpose	Validation and basic awareness	ERD visualization and layout
Maintenance	Per-entity updates	Central configuration management
Cardinality	Basic (many-to-one)	Detailed (from_cardinality, to_cardinality)
Visual Properties	None	Positioning, colors, labels

Phase-Based Implementation Strategy

Phase 1: System Analysis and Schema Enhancement

Timeline: Weeks 1-2
Focus: Foundation and standardization

1.1 Comprehensive Relationship Audit

• Compare all 35 schema metadata relationships against ERD manual relationships
• Identify missing, inconsistent, or duplicate definitions across systems
• Document discrepancies and establish resolution priorities
• Generate relationship coverage matrix for validation

1.2 Enhanced Schema Format Definition

Drawing on industry best practices, establish standardized schema format:

{
  "boost_metadata": {
    "relationships": [
      {
        "field": "equipmentIds",
        "targetEntity": "Equipment", 
        "relationshipType": "one-to-many",
        "required": false,
        "label": "owns_equipment",
        "erdProperties": {
          "type": "identifying",
          "from_cardinality": "one",
          "to_cardinality": "many",
          "visual_label": "owns equipment"
        }
      }
    ]
  }
}

1.3 Schema Metadata Enhancement

• Update all 35 entity schemas with complete relationship information
• Ensure bidirectional consistency (A→B implies B←A where appropriate)
• Add ERD-specific properties to existing relationship definitions
• Implement validation rules for relationship schema compliance

Phase 2: ERD Generation Tool Development

Timeline: Weeks 3-4
Focus: Automation infrastructure

2.1 ERD Configuration Generator Implementation

class ERDConfigGenerator:
    """Schema-first ERD configuration generation tool"""
    
    def generate_erd_config(self) -> dict:
        relationships = []
        
        for entity_name, entity_schema in self.entities.items():
            entity_relationships = self.extract_relationships(entity_schema)
            relationships.extend(entity_relationships)
        
        return {
            "areas": self.preserve_areas(),
            "entity_display": self.preserve_positioning(),  
            "manual_relationships": relationships,
            "field_mappings": self.generate_field_mappings()
        }

2.2 Visual Layout Preservation

• Maintain existing entity positioning and area configurations
• Support manual override capabilities for visual customization
• Preserve styling and layout preferences from current ERD configuration

2.3 Generation Tool Testing and Validation
