Steps
Reference the EPCIS 2.0 standard, which added JSON/JSON-LD support and a standardized RESTful capture/query API alongside the original XML format
Model traceability events around the 'what/when/where/why' structure — object identifiers (e.g., GTIN, lot/serial), event time, location (GLN), and business step/disposition
Capture events (e.g., an ObjectEvent for a garment shipment) to an EPCIS-conformant capture endpoint, using JSON-LD for web-native interoperability
Query event history through the standardized REST query interface to reconstruct a product's chain-of-custody
Pair EPCIS events with GS1 Digital Link identifiers so a single scanned code resolves to both product info and its traceability history
Known gotchas
EPCIS defines the data model and API pattern, not a single hosted service — you still need an EPCIS-conformant repository (open-source implementation or vendor platform) to actually store/query events
XML-based EPCIS 1.x events and JSON/JSON-LD EPCIS 2.0 events are not automatically interchangeable — a mixed-format supply chain needs an explicit conversion step
Business step/disposition ('why') values come from a controlled Core Business Vocabulary — free-text values break interoperability with trading partners
