Perishable Goods Network
Example business network that shows growers, shippers and importers defining contracts for the price of perishable goods, based on temperature readings received for shipping containers.
The business network defines a contract between growers and importers. The contract stipulates that: On receipt of the shipment the importer pays the grower the unit price x the number of units in the shipment. Shipments that arrive late are free. Shipments that have breached the low temperate threshold have a penalty applied proportional to the magnitude of the breach x a penalty factor. Shipments that have breached the high temperate threshold have a penalty applied proportional to the magnitude of the breach x a penalty factor.
This business network defines:

TemperatureReading ShipmentReceived SetupDemo
To test this Business Network Definition in the Test tab:
Submit a SetupDemo transaction:
{
"$class": "org.acme.shipping.perishable.SetupDemo"
}
This transaction populates the Participant Registries with a Grower, an Importer and a Shipper. The Asset Registries will have a Contract asset and a Shipment asset.
Submit a TemperatureReading transaction:
{
"$class": "org.acme.shipping.perishable.TemperatureReading",
"centigrade": 8,
"shipment": "resource:org.acme.shipping.perishable.Shipment#SHIP_001"
}
If the temperature reading falls outside the min/max range of the contract, the price received by the grower will be reduced. You may submit several readings if you wish. Each reading will be aggregated within SHIP_001 Shipment Asset Registry.
Submit a ShipmentReceived transaction for SHIP_001 to trigger the payout to the grower, based on the parameters of the CON_001 contract:
{
"$class": "org.acme.shipping.perishable.ShipmentReceived",
"shipment": "resource:org.acme.shipping.perishable.Shipment#SHIP_001"
}
If the date-time of the ShipmentReceived transaction is after the arrivalDateTime on CON_001 then the grower will no receive any payment for the shipment.
Congratulations!
