EDI.
Legacy exchange lives in XML. The gateway's translator takes EPCIS 1.1, 1.2 and 2.0 XML in and returns EPCIS 2.0 JSON-LD, with a round-trip fidelity report per job so the translation is reviewable rather than trusted. That translator is built and under test. A hosted EDI-exchange product is not something this site claims; the migration path is what ships.

Build state, 29 July 2026. The capture gateway is written and passing its conformance tests; nothing is hosted yet. See How for the dimension, and What ships today for the dated ledger.
