The Product Tracking pallet provides functionality for registering and tracking shipments, and monitoring their storage and transportation conditions, within a fictitious supply chain between various stakeholders. The high-level flow is shown below.

This pallet is part of the Substrate Enterprise sample.

It is inspired by existing projects & standards:

• IBM Food Trust
• Hyperledger Grid
• GS1 Standards

NOTE: This pallet implements the aforementionned process in a simplified way, thus it is intended for demonstration purposes and is not audited or ready for production use.

To register a shipment, one must send a transaction with a productTracking.registerShipment extrinsic with the following arguments:

• id as the Shipment ID, an arbitrary numeric or alpha-numeric code that uniquely identifies the shipment.
• owner as the Substrate Account representing the person (or function within an organization) responsible for the shipping process of the given shipment.
• products which is a series of product IDs associated with the given shipment.

When a shipment has been registered, shippting events occuring during the shipment's lifecycle can be recorded on-chain by sending a productTracking.trackShipment extrinsic with the following argmuments:

• id is the Shipment ID which identifies which shipment is being tracked.
• operation as the business operation that took place during the shipping process: Pickup, Scan or Deliver.
• timestamp as time (represented as UNIX time) at which the event was captured by an external system or sensor.
• location is an optional ReadPoint which contains the geographic position (latitude and longitude) where the event was captured.
• readings which is an optional series of Reading that represent data captured by various sensors (humidity, Temperature, vibration, etc). A Reading includes a device_id (unique idenfitier of the device), a reading_type (type of sensor / measurement, see ReadingType enum), a timestamp (time at which the reading was recorded), and a value as the actual measurement recorded by the sensor.

This pallet depends on on the [FRAME EnsureOrigin System trait]

frame_support::traits::EnsureOrigin;

This pallet depends on on the FRAME Timestamp & Product registry pallets.

Run the tests with:

```
cargo test
```

To add this pallet to your runtime, simply include the following to your runtime's Cargo.toml file:

[dependencies.product-tracking]
default_features = false
package = 'pallet-product-tracking'
version = '2.0.0'

and update your runtime's std feature to include this pallet:

std = [
    # --snip--
    'product-tracking/std',
]

You should implement it's trait like so:

/// Used for test_module
impl product_tracking::Trait for Runtime {
    type Event = Event;
    type CreateRoleOrigin = Origin;
}

and include it in your construct_runtime! macro:

ProductTracking: product_tracking::{Module, Call, Storage, Event<T>},

This template pallet does not have any genesis configuration.
