How EPCIS and CBV Benefit the Retail Industry?

EPCIS 2.0 is the GS1 standard for supply-chain event data, and epcis.dev is a capture gateway for it: post an event and the door validates it against GS1's own schema, stamps who captured it, hashes it by CBV 2.0, and appends. That is the ground the topic above stands on.

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 is written and under test.

Identity is the standard's own. The gateway computes the standardized EPCIS event hash from CBV 2.0 §8.9, with GS1 Digital Link normalisation, checked against pinned reference vectors, so the same event captured twice is the same event and a changed event is a different one.

Build state, 29 July 2026. The capture gateway is written and its conformance tests pass against GS1's normative artefacts. Nothing is hosted yet: there is no public endpoint, no key to hold, and no account to open. Today the interface answers on your own machine under wrangler dev; the full ledger is at What ships today.
