Generates the EPCIS 2.0 event hash (hash ID) for EPCIS documents and events in XML or JSON/JSON-LD, following the GS1 CBV 2.0 and 2.1 canonical pre-hash rules. The same event in either format produces the same hash, so duplicates are easy to detect. Java library, CLI, REST API and Quarkus extension.

Java models for GS1 EPCIS 2.0 and CBV 2.0 supply chain traceability: documents, events, master data, queries and subscriptions, with Jackson (JSON/JSON-LD) and JAXB (XML) bindings, GS1 Web Vocabulary classes and a Quarkus extension.

Generate valid EPCIS 2.0 and CBV 2.0 test events in JSON/JSON-LD or XML; GS1 Digital Link and EPC URIs, randomized serials and timestamps, event hash IDs. Available as a Java/Quarkus library, a REST API and a free online tool.
