Leveraging EPCIS for efficient supply chain management

Underneath this topic sits one mechanism: an EPCIS 2.0 capture gateway. epcis.dev is one — every posted event is validated against GS1's own schema, stamped with the capturing account (capturedBy, the warrantor, kept distinct from who, the attested observer), hashed by CBV 2.0, and appended, never edited. Hold the topic above against that ground and it stays concrete.

The concrete gain is evidentiary, not cosmetic. Events validated at capture cannot drift from the standard; the CBV §8.9 hash makes a duplicate the same event and an edit a different one; and an append-only store means the answer to a later dispute, recall or audit is a chain of records that nobody — including the operator — could rewrite. The cost that disappears is the reconciliation meeting.

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.

Custody is structural, not promised. No service identity holds an UPDATE or DELETE grant; the write path has exactly one writer and it can only append. You can add an event; you cannot un-write one, which is what makes a later trace evidentiary rather than merely stored.
