Digital Thread BOM Mapping Framework (UML + JSON Schema)
The Digital Thread BOM Mapping Framework is a standardized, model-driven approach that establishes bidirectional traceability and semantic interoperability between heterogeneous Bill of Materials representations across the product lifecycle—from design (EBOM) to manufacturing (MBOM) to service (SBOM). It leverages UML-based modeling for structural and behavioral specification and defines a rigorous JSON Schema to enforce data fidelity, versioning, and context-aware linkage in digital thread implementations.

📖 Overview
At its core, the Digital Thread BOM Mapping Framework bridges siloed engineering domains by formalizing how BOM artifacts—each governed by distinct semantics, ownership, and granularity—are related, transformed, and synchronized. It employs UML class diagrams to define domain-specific BOM metamodels (e.g., Part, ItemRevision, BOMStructure, RelationshipType), sequence diagrams to capture transformation workflows (e.g., EBOM-to-MBOM release), and profiled stereotypes (e.g., <<Traceable>>, <<Versioned>>) to annotate traceability constraints. The accompanying JSON Schema provides machine-readable validation rules for serialized BOM mappings—including required identifiers (e.g., globalPartId, revisionId), relationship cardinalities (1:1, 1:N, N:M), lifecycle BOM Version Control Best Practices
