Schema & Compliance
Open, typed schemas for DeviceStamp events. Map lifecycle data to DPP and ESPR attributes with standardized JSON-LD structures.
Overview
DeviceStamp uses open, JSON-LD typed schemas to represent verifiable lifecycle events. Every record—from grading and repair to data wiping and resale—is captured in a standardized format that maps directly to EU Digital Product Passport (DPP) and ESPR compliance requirements.
Our schema is designed to be:
- Interoperable — Compatible with GS1 standards and vendor systems
- Verifiable — Each event is anchored on-chain with cryptographic proof
- Privacy-first — No personal data stored on-chain; only hashes and selectively disclosed fields
- Extensible — Support for custom attributes while maintaining compliance
Key Features
Event Types: Manufacturing origin, repair history, grading & testing, data wiping, sales & marketplace transfers, recycling & end-of-life.
Data Structure: Immutable records with timestamps, actor wallets, event signatures, and artifact references (IPFS CIDs for photos, reports, certificates).
Compliance Ready: Fields map to DPP lifecycle phases and ESPR transparency requirements for 2027+ regulations.
