EPCIS and CBV for Cold Chain Management
The gateway framing matters for this topic: epcis.dev accepts an event only after validating it against GS1's own schema, stamps the capturing account — capturedBy, the warrantor, kept distinct from who, the attested observer — identifies it by its CBV 2.0 hash, and appends it to a store nothing rewrites. What follows stands on those mechanics.
Whatever the setting, the mechanics underneath this topic are the same four moves: an event is captured at a door, validated against GS1's official EPCIS 2.0 schema, identified by the CBV 2.0 §8.9 hash of its own content, and appended to a store nothing can rewrite. The variations between industries and use cases are vocabulary — the CBV's business steps and dispositions — not architecture.
Ten years of vendor XML has a path forward: EPCIS 1.1, 1.2 and 2.0 XML in, EPCIS 2.0 JSON-LD out, with a round-trip fidelity report per job so the translation is something you review rather than something you trust. That translator answers at POST /translate on this origin.
The same door answers people and agents. Capture, query, get_event, trace and translate are exposed over MCP, so a logistics agent captures and queries with the same key a person would use, without a human copying values between two systems.

Proof, not adjectives. The gateway's conformance tests pass against GS1's normative artifacts, and the calculators answer on this origin — POST /translate, /validate, /hash, no key. The dated ledger is What ships today.
