Nodes

{
	nodeLabel: "{PaymentMethodGenericLib.PAYMENTMETHOD_GRAPH_NODE_LABEL}", // "paymentMethod"
	schema: {
		identifier: true,
		restrictProperties: true,
		restrictRelationships: true,
		properties: {
			paymentMethodId: {
				identifier: true, // create unique id from translation
			},
			currencyId: {
				immutable: true, // currently not have data model for allowing this to be changed, is immutable
			},
		},
	}
}

{
	nodeLabel: "{PaymentMethodGenericLib.USERPAYMENTMETHOD_GRAPH_NODE_LABEL}", // "userPaymentMethod"
	schema: {
		identifier: true,
		restrictProperties: true,
		restrictRelationships: true,
		properties: {
			userPaymentMethodId: {
				identifier: true, // create unique id from user and uniqueMessageId
			},
			paymentMethodId: { // stored here to reduce queries finding matching methods, eg sellOffers
				immutable: true,
			},
			userPaymentMethodTag: { // users reference name for this userPaymentMethod
			},
		},
	}
}

• adds a node between a user and a payment method
• this is the node linked to by sellOfferPlans

{
	nodeLabel: "{PaymentMethodGenericLib.PAYMENTMETHOD_GRAPH_NODE_LABEL}PropertyLabel",
}
{
	nodeLabel: "{PaymentMethodGenericLib.PAYMENTMETHOD_GRAPH_NODE_LABEL}Property",
}

{
	nodeLabel: "{PaymentMethodGenericLib.USERPAYMENTMETHOD_GRAPH_NODE_LABEL}PropertyLabel",
}
{
	nodeLabel: "{PaymentMethodGenericLib.USERPAYMENTMETHOD_GRAPH_NODE_LABEL}Property",
}

{
	nodeLabel: "{PaymentMethodGenericLib.USERPAYMENTMETHOD_SALE_PROPERTIES_GRAPH_TAG}PropertyLabel", // userPaymentMethodSalePropertyLabel
}
{
	nodeLabel: "{PaymentMethodGenericLib.USERPAYMENTMETHOD_SALE_PROPERTIES_GRAPH_TAG}Property",
}

• see DataSchemaLib
• two sets of property nodes for userPaymentMethod, one for presentation properties (when browsing), paymentMethodSale for after sale, properties that get sent to the buyer, eg bank account number

Relationships

{
	relationshipType: "{PaymentMethodGenericLib.createIsPaymentMethodGraphRelationshipType()}", // "is_paymentMethod"
	schema: {
		elementCanBeRemoved: false,
		allPropertiesImmutable: true,
		restrictProperties: true,
		properties: {
			originTimestamp: //timestamp the request to create/change this relationship was sent
		},
	}
}

{
	relationshipType: "{PaymentMethodGenericLib.createIsUserPaymentMethodGraphRelationshipType()}", // "is_userPaymentMethod"
	schema: {
		elementCanBeRemoved: false,
		allPropertiesImmutable: true,
		restrictProperties: true,
		properties: {
			originTimestamp: //timestamp the request to create/change this relationship was sent
		},
	}
}

• not setup logic to disable userPaymentMethods at this time

{
	relationshipType: "has_{PaymentMethodGenericLib.PAYMENTMETHOD_GRAPH_NODE_LABEL}Property",
}
{
	relationshipType: "disabled_{PaymentMethodGenericLib.PAYMENTMETHOD_GRAPH_NODE_LABEL}Property",
}
{
	relationshipType: "is_{PaymentMethodGenericLib.PAYMENTMETHOD_GRAPH_NODE_LABEL}PropertyLabel",
}

{
	relationshipType: "has_{PaymentMethodGenericLib.USERPAYMENTMETHOD_GRAPH_NODE_LABEL}Property",
}
{
	relationshipType: "disabled_{PaymentMethodGenericLib.USERPAYMENTMETHOD_GRAPH_NODE_LABEL}Property",
}
{
	relationshipType: "is_{PaymentMethodGenericLib.USERPAYMENTMETHOD_GRAPH_NODE_LABEL}PropertyLabel",
}

{
	relationshipType: "has_{PaymentMethodGenericLib.USERPAYMENTMETHOD_SALE_PROPERTIES_GRAPH_TAG}Property",
}

Data structure notes

• Users can create new paymentMethods which are uniquely identified by their translation
• Users can create userPaymentMethod nodes for their account which connect to paymentMethods, one user can have multiple userPaymentMethod links to the same paymentMethod, eg different Bank Transfer nodes for different bank accounts, which can be applied to sell offers in any combination
