# Knowledge Graph Builder
## Advanced Knowledge Graph Construction for Enhanced BMAD System
The Knowledge Graph Builder creates comprehensive, interconnected knowledge representations that capture relationships between code, concepts, patterns, decisions, and outcomes across all development activities.
### Knowledge Graph Architecture
#### Multi-Dimensional Knowledge Representation
```yaml
knowledge_graph_structure:

concept_nodes:
- code_concepts: "Functions, classes, modules, patterns"
- domain_concepts: "Business logic, requirements, features"
- technical_concepts: "Architectures, technologies, frameworks"
- process_concepts: "Workflows, methodologies, practices"
- team_concepts: "Roles, skills, collaboration patterns"
artifact_nodes:
- code_artifacts: "Files, components, libraries, APIs"
- documentation_artifacts: "READMEs, specs, comments"
- decision_artifacts: "ADRs, meeting notes, rationale"
- test_artifacts: "Test cases, scenarios, coverage data"
- deployment_artifacts: "Configs, scripts, environments"
relationship_nodes:
- dependency_relationships: "Uses, imports, calls, inherits"
- semantic_relationships: "Similar to, implements, abstracts"
- temporal_relationships: "Before, after, during, triggers"
- causality_relationships: "Causes, prevents, enables, blocks"
- collaboration_relationships: "Authored by, reviewed by, approved by"
context_nodes:
- project_contexts: "Project phases, milestones, goals"
- team_contexts: "Team structure, skills, availability"
- technical_contexts: "Environment, constraints, limitations"
- business_contexts: "Requirements, priorities, deadlines"
- quality_contexts: "Standards, criteria, metrics"
edge_types:
structural_edges:
- composition: "Part of, contains, includes"
- inheritance: "Extends, implements, derives from"
- association: "Uses, references, calls"
- aggregation: "Composed of, made from, built with"
semantic_edges:
- similarity: "Similar to, related to, analogous to"
- classification: "Type of, instance of, category of"
- transformation: "Converts to, maps to, becomes"
- equivalence: "Same as, alias for, identical to"
temporal_edges:
- sequence: "Followed by, preceded by, concurrent with"
- causality: "Causes, results in, leads to"
- lifecycle: "Created, modified, deprecated, removed"
- versioning: "Previous version, next version, variant of"
contextual_edges:
- applicability: "Used in, applies to, relevant for"
- constraint: "Requires, depends on, limited by"
- optimization: "Improves, enhances, optimizes"
- conflict: "Conflicts with, incompatible with, blocks"
