Community-supported agriculture (CSA model) or cropsharing is a system that connects producers and consumers within the food system closer by allowing the consumer to subscribe to the harvest of a certain farm or group of farms.

CSA stands for AMAP in French.

To support this use case in the ontology needs to:

1. As a CSA Producer I need to represent a recurring subscription of a consumer so that I know how many products to harvest.

• The Onotology will include a Contract class, that has a startDate, frequency, endDate (optional) & NoOfOccurences (optional).
• Contracts will be linked a single managingAgent , a single contractedAgent, and one or more CataologItems.
• Contracts will generate Orders.

2. As a CSA Producer I need to represent the content of each Share (which will vary week on week) so that I can browse the history

• Share Products will be mapped via TransformationFlows to the individual Products they contain.
• A new Product must be created for each recurrence of the Share.

3. As a CSA Producer I need to represent a recurring distribution session to allow planning.

• A Contract will be linked to mutliple SaleSession detailing the recurring distributions of the Share Product

@Alcoz - does that cover it ?
