These examples demonstrate how the Winter Protocol metadata format can be used to capture and represent different events in the Ceylon Cinnamon supply chain. The object event represents the harvesting of Ceylon Cinnamon by farmers, capturing relevant details such as location, quality, weight, and batch number. The transformation event represents the processing of the harvested cinnamon into finished products, such as cinnamon quills, by processors. It includes information about the processing facility, quality, weight, and processing details. Finally, the transaction event represents the sale of the processed Ceylon Cinnamon to buyers, including details about the buyer, sale price, and sale date.
