The Product Registry pallet provides functionality for registering and managing master data (aka class-level) about products / trade items exchanged in a supply chain between various stakeholders. This data is typically registered once by the product's manufacturer / supplier to be shared with other network participants.

When this pallet is added to a Subtrate runtime, other custom Substrate pallets can then implement additional business logic leveraging this Product Registry pallet as a reference for known products and their owning organizations.

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 product, one must send a transaction with a productRegistry.registerProduct extrinsic with the following arguments:

• id as the Product ID, typically this would be a GS1 GTIN (Global Trade Item Number), or ASIN (Amazon Standard Identification Number), or similar, a numeric or alpha-numeric code with a well-defined data structure.
• owner as the Substrate Account representing the organization owning this product, as in the manufacturer or supplier providing this product within the value chain.
• props which is a series of properties (name & value) describing the product. Typically, there would at least be a textual description, and SKU. It could also contain instance / lot master data e.g. expiration, weight, harvest date.

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

frame_support::traits::EnsureOrigin;

This pallet depends on on the FRAME Timestamp pallet.

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-registry]
default_features = false
package = 'pallet-product-registry'
version = '2.0.0'

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

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

You should implement it's trait like so:

impl product_registry::Trait for Runtime {
	type Event = Event;
	type CreateRoleOrigin = Origin;
}

and include it in your construct_runtime! macro:

ProductRegistry: product_registry::{Module, Call, Storage, Event<T>},

This template pallet does not have any genesis configuration.
