Vehicle Lifecycle Network
This network tracks the Lifecycle of Vehicles from manufacture to being scrapped involving private owners, manufacturers and scrap merchants. A regulator is able to provide oversight throughout this whole process.
This business network defines:
Participants
AuctionHouse Company Manufacturer PrivateOwner Regulator ScrapMerchant
Assets
Order Vehicle
Transactions
PlaceOrder UpdateOrderStatus ApplicationForVehicleRegistrationCertificate PrivateVehicleTransfer ScrapVehicle UpdateSuspicious ScrapAllVehiclesByColour SetupDemo
Events
PlaceOrderEvent UpdateOrderStatusEvent ScrapVehicleEvent
A PriavteOwner participant would submit a PlaceOrder transaction, through a Manufacturer's application. A Manufacturer would submit an UpdateOrderStatus transaction which would be the Vehicle being manufactured. They would apply for a registration certificate by submitting an ApplicationForVehicleRegistrationCertificate transaction. After the vehicle has been manufactured they would submit a PrivateVehicleTransfer transaction. A Regulator would be able perform oversight over this whole process and submit an UpdateSuspicious transaction to view any suspicious vehicles that may be out of compliance with regulations. A ScrapMerchant would be able to submit a ScrapVehicle or a ScrapAllVehiclesByColour transaction to complete the lifecycle of a vehicle.
To test this Business Network Definition in the Test tab:
Submit a SetupDemo transaction:
{
"$class": "org.acme.vehicle.lifecycle.SetupDemo"
}
This transaction populates the Participant Registries with three Manufacturer participants, twenty-three PrivateOwner participants and a Regulator participant. The Vehicle Asset Registry will have thirteen Vehicle assets.
Submit a PlaceOrder transaction:
{
"$class": "org.acme.vehicle.lifecycle.manufacturer.PlaceOrder",
"orderId": "1234",
"vehicleDetails": {
"$class": "org.vda.VehicleDetails",
"make": "Arium",
"modelType": "Gamora",
"colour": "Sunburst Orange"
},
"manufacturer": "resource:org.acme.vehicle.lifecycle.manufacturer.Manufacturer#Arium",
"orderer": "resource:org.acme.vehicle.lifecycle.PrivateOwner#toby"
}
This PlaceOrder transaction creates a new order in the Order Asset Registry. It also emits a PlaceOrderEvent events.
Submit a UpdateOrderStatus transaction:
{
"$class": "org.acme.vehicle.lifecycle.manufacturer.UpdateOrderStatus",
"orderStatus": "SCHEDULED_FOR_MANUFACTURE",
"order": "resource:org.acme.vehicle.lifecycle.manufacturer.Order#1234"
}
This UpdateOrderStatus transaction updates the order status of orderId:1234 in the Order Asset Registry. It also emits a UpdateOrderStatusEvent event.
Congratulations!
