Nodes

{
	nodeLabel: "{SellOfferStandardLib.SELL_OFFER_GRAPH_NODE_LABEL}",
	schema: {
		identifier: true,
		restrictProperties: true,
		restrictRelationships: true,
		properties: {
			sellOfferId: {
				identifier: true, //(random uuid)
			},
			productId: {
				immutable: true,
			},
			sellOfferHandlerServiceNameTag: {
				immutable: true,
			},
			currencyId: {
				immutable: true, // matches the sellOfferPlan's currencyId
			},
		},
	}
}

Relationships

{
	relationshipType: "{SellOfferStandardLib.createHasSellOfferGraphRelationshipType()}", //"has_sellOffer"
	schema: {
		elementCanBeRemoved: true,
		allPropertiesImmutable: true,
		restrictProperties: true,
		properties: {
			originTimestamp: //timestamp the request to create/change this relationship was sent
		},
	}
}

{
	relationshipType: "{SellOfferStandardLib.createDisabledSellOfferGraphRelationshipType()}", //"disabled_sellOffer"
	schema: {
		elementCanBeRemoved: true,
		allPropertiesImmutable: true,
		restrictProperties: true,
		properties: {
			originTimestamp: //timestamp the request to create/change this relationship was sent
		},
	}
}

• SellOffer relationship links the sell offer with it's parent product, the sell offer can be enabled (hasSellOffer) or disabled (disabledSellOffer)
• when enabling/disabling we remove the old relationship and replace it with the new setting

{
	relationshipType: "{SellOfferPlanLib.createUsesSellOfferPlanGraphRelationshipType()}", // "uses_sellOfferPlan"
	schema: {
		elementCanBeRemoved: true,
		allPropertiesImmutable: true,
		restrictProperties: true,
		properties: {
			originTimestamp: //timestamp the request to create/change this relationship was sent
		},
	}
}

• links a sell offer to a sell offer plan
• a sell offer has only one sell offer plan

Complex Filter requests

// Not sure if moving all to sellOfferManager
{
	filterType: "sellOffer" //unique id is sellOfferId
	type: "group",
	elements:
	[
		// ...
		{
			type: "complexFilter",
			complexFilter: {
				filterType: "sellOfferPlan",
				// see [[Service - Sell Offer Plan|Complex Filter requests]]
			}
		},		
		{
			type: "complexFilter",
			complexFilter: {
				filterType: "sellOfferTermLink",
				// see [[Service - Sell Offer Terms|Complex Filter requests]]
			}
		},		
		...
	]
}

SellOffer currency

• When creating a sellOffer it's currency will be set to the same as the sellOfferPlan chosen
• All deliveryMethods added to the sellOfferPlan must be the same currency as the sellOfferPlan, so total price can be calculated accurately
• paymentMethod does not need to match the sellOfferPlan currency, seller can have sellOfferTerms to explain currency conversion when making payment
