CTEs

The following are the basic Critical Tracking Events for Seafood Traceability:

Common Name for Event EPCIS Event Type - ACTION - bizstep - objects

BOLD Indicates Minimum External CTEs Required by Next Point in Supply Chain

Receive Feed ObjectEvent - OBSERVE - receiving - QR URL or GTIN/Lot, GTIN/Serial containers of feed
Fertilize Eggs ObjectEvent - ADD - commissioning - QR URL or GTIN/Lot for fish eggs
Raise Fish on Fish Farm TransformationEvent - ADD - commissioning - inputs (fish eggs, feed) outputs (mature fish)
ID Harvest Container ObjectEvent - ADD - commissioning - QR URL or GRAI for container
Harvest Fish into Container AggregationEvent - ADD - packing - container (parent) fish (children)
Send Container of Fish to Processor ObjectEvent - OBSERVE - shipping - container - sourceList & destinationList
Receive Fish at Processor ObjectEvent - OBSERVE - receiving - container - sourceList & destinationList
Unpack Container of Fish at Processor ObjectEvent - DELETE - unpacking - container
Process Fish and Label with GS1-128 Barcoded Case Label TransformationEvent - ADD - commissioning - inputs (mature fish) outputs (processed fish GTIN+Lot) - Required KDEs listed under Instance Level Master Data (ILMD)
Create Pallet Label with GS1-128 Barcode ObjectEvent - ADD - commissioning - Pallet SSCC
Pack and ship cases to Customer AggregationEvent - ADD - shipping - Pallet (parent) Cases (children) - sourceList & destinationList

BOLD Indicates Minimum External CTEs Required by Next Point in Supply Chain

ID Harvest Container ObjectEvent - ADD - commissioning - QR URL or GRAI for container
Catch Fish ObjectEvent - ADD - commissioning - QR URL, GTIN/Lot or GTIN/Serial for catch event, Required KDEs listed under Instance Level Master Data (ILMD)
Harvest Fish into Container AggregationEvent - ADD - packing - container (parent) fish (children)
Landing at Dock - unload fish from container ObjectEvent - DELETE - unpack - container where the readPoint is the dock geo location and bizLocation is the globally unique dock identity
- alternatively, container may be shipped to next buyer as is, then unloaded by buyer
Send Fish to Processor ObjectEvent - OBSERVE - shipping - catch ID - sourceList & destinationList
Receive Fish at Processor ObjectEvent - OBSERVE - receiving - catch ID - sourceList & destinationList
Process Fish and Label with GS1-128 Barcoded Case Label TransformationEvent - ADD - commissioning - inputs (mature fish) outputs (processed fish GTIN+Lot) - Required KDEs listed under Instance Level Master Data (ILMD)
Create Pallet Label with GS1-128 Barcode ObjectEvent - ADD - commissioning - Pallet SSCC
Pack and Ship Cases to Customer AggregationEvent - ADD - shipping - Pallet (parent) Cases (children) - sourceList & destinationList

Treat the transship as the dock and processor.
Capture the unload point from GPS (where in the ocean) and store it in readPoint ObjectEvent - DELETE - unpacking - container.
Then use ObjectEvent - OBSERVE - shipping - sourceList & destinationList to capture the original and new vessel information.
