Modeling Supply Chain Evidence: Condition, Asset, and Custody Data Schemas for IoT Hardware
Short summary
IoT supply chain tracking requires three evidence schemas—condition (sensors with calibration metadata), asset (reusable container lifecycle), custody (handover chain)—to meet regulatory mandates like FSMA 204 and EU GDP. Raw data dumps fail compliance audits; structured, auditable evidence is required to prove product integrity and attribute excursions. Cold chain market projected to grow USD 8.3B (2025) to USD 15B (2030).
- •Three distinct evidence dimensions (condition, asset, custody) map to different operational and regulatory use cases
- •Calibration metadata, audit trails, and condition snapshots at handovers are mandatory for regulated industries
- •Regulators demand proof of control and conditions, not just location tracking; market growth follows compliance adoption
