How to Choose the Right EPCIS and CBV Solution Provider?

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 the capturing account — capturedBy, the warrantor, kept distinct from who, the attested observer — hashes it by CBV 2.0, and appends. That is the ground the topic above stands on.

The implementation order that works: validate first — every event against the official GS1 schema, failures refused in the standard's own exception types — then bring the archive along, EPCIS 1.1/1.2 XML through translation with a per-job fidelity report, then make the store append-only so custody is structural rather than promised. Each step is checkable on its own before the next begins, and this gateway implements all three.

The part epcis.dev makes concrete is validation. Every event is machine-checked against the official GS1 EPCIS 2.0 JSON schema before it is accepted, and a capture that does not validate is refused as application/problem+json carrying the standard's own exception types, not a vendor error string.

Reads are minimally scoped. You see your own scope; what is outside it is absent, not greyed out and not redacted, so there is no shape left behind to argue about. Recording an event is $0 by policy — intent, until published terms bind it — because a stream that charges per event is one you stop feeding the month the bill grows with volume.
