One platform to find, translate, and explore Digital Product Passports across every industry standard.
This research designs, implements, and evaluates a DPP Interoperability Platform as a Design Science Research artifact. The platform normalises passports from Battery Pass, Tractus-X, and food initiatives into a Shared Core Schema v0.2, resolves 11 identifier types, and exposes 21 REST endpoints. Evaluation confirms cross-initiative round-trip fidelity and SHACL conformance.
A Master's thesis evaluating interoperability across European Digital Product Passport frameworks using a shared core schema and two microservices.
Legal Mandate
ESPR Article 4 requires all regulated product categories to carry a machine-readable DPP from 2027 onwards.
19 Core Fields
A Shared Core Schema v0.2 defines 19 mandatory leaf fields covering identity, manufacturer, product, and data carrier.
Per-Item Tracking
Each physical product unit gets its own passport — not just a model — enabling lot, batch, and item-level traceability.
Persistent Identity
Passports are identified by durable URIs (UUID, GTIN, DID, DPP_URN) resolved across 11 identifier types.
Paste a product passport payload or enter an identifier. The platform accepts JSON and JSON-LD from any supported initiative.
Paste a product passport payload or enter an identifier. The platform accepts JSON and JSON-LD from any supported initiative.
The platform resolves the identifier, matches it across registries, and normalizes the passport into the Shared Core Schema with confidence scoring and provenance tracking.
Your translated passport becomes part of a connected knowledge graph. Query with SPARQL, compare products, and discover relationships across initiatives.
Browse example Digital Product Passports across fashion, battery, furniture, and electronics categories.
