• controls ownership of a rateTable, many deliveryMethods can point to one rateTable but only one deliveryMethod controls it (RBAC for that deliveryMethods allows control over the rateTable)

}

Data structure notes

• Users can create new deliveryMethods which are uniquely identified by their translation
• deliveryMethods have RBAC structure, default to creator having admin permissions, but admin can add other roles etc..
• Any user can attach any deliveryMethod to a SellOfferPlan
• deliveryMethods do not set a currency, that will come from the paymentMethod chosen in a sellOffer plan, deliveryMethods just return a value that is added into a pricing total, assumed to be the currency of the paymentMethod however we could get more complicated in sellOfferPlanDeliveryMethodLinks to do conversions etc
