Reference architecture
Decouple identity, events and enterprise integration.
A conceptual architecture separates identifier management from event ingestion, query services and integration adapters.
1
Identity service
Namespaces, identifier issuance, aliases and resolution.
2
Event service
Append-only lifecycle and traceability event capture.
3
Query layer
Current state, history, provenance and relationship queries.
4
Connectors
ERP, MES, WMS, PLM, IoT, EPCIS and partner integrations.
Conceptual data flow
Operational systems remain systems of record while the API layer normalizes identity and traceability interactions.
Design principle: avoid making one global identifier format carry every business meaning. Keep identity stable and model business context in linked attributes and events.
