Applying EPCIS to Humanitarian Aid and Disaster Relief

Start from the record, not the buzzword. An EPCIS 2.0 event is a validated, hashed, appended fact, and epcis.dev is a capture gateway that enforces exactly that: GS1's own schema at the door, the capturing account stamped — capturedBy, the warrantor, kept distinct from who, the attested observer — the CBV 2.0 hash as the event's identity, and no way to un-write. The topic above is read against that record.

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.

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

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.
