FoodFast Basic Business Network

(Developed in Composer)

When ordering food online, punctuality is a big part of the experience. You don't want your meetings get interrupted because of a late arriving food order. The customers of online food ordering portals can now see the "promised delivery times" and the "actual delivery times" of the restaurants, along with the experience-based user ratings.

• Entrepreneurs can offer services to the slow-delivering restaurants
• Customers can have a better understanding of when their food will arrive: better satisfaction
• Encourages restaurants to plan better. New restaurants will have more chances of competing with older, bigger restaurants
• Paid ratings will be less misleading

This business network defines:

Participant Restaurant

Asset FoodORder

Transaction FoodTransaction

Event FoodEvent

FoodOrders are created by a Restaurant, and the value property on a FoodOrder can be modified by submitting a FoodTransaction. The FoodTransaction emits a FoodEvent that notifies applications of the old and new values for each modified FoodOrders.

To test this Business Network Definition in the Test tab:

Create a Restaurant participant:

{
  "$class": "org.foodfast.reputation.Restaurant",
  "restaurantId": "restaurantId:0001",
  "restaurantName": "Tisch&Tschips"
}

Create a FoodOrder asset:

{
  "$class": "org.foodfast.reputation.FoodOrder",
  "orderId": "orderId:1001",
  "owner": "resource:org.foodfast.reputation.Restaurant#restaurantId:0001",
  "orderTime": 40,
  "deliveryTime": -1,
  "deliveryStatus": "RECEIVED"
}

Submit a FoodTransaction transaction:

{
  "$class": "org.foodfast.reputation.FoodTransaction",
  "order": "resource:org.foodfast.reputation.FoodOrder#orderId:1001",
  "deliveryTime": 35,
  "deliveryStatus": "DELIVERED"
}

After submitting this transaction, you should now see the transaction in the Transaction Registry and that a FoodEvent has been emitted. As a result, the value of the orderId:1001 should now be deliveryTime = 35 in the Asset Registry.
