Properties from Demand

Property	Expected Type	description
acceptedPaymentMethod	PaymentMethod LoanOrCredit	The payment method(s) accepted by seller for this offer.
advanceBookingRequirement	QuantitativeValue	The amount of time that is required between accepting the offer and the actual usage of the resource or service.
areaServed	Text Place GeoShape AdministrativeArea	The geographic area where a service or offered item is provided.
asin	Text URL	An Amazon Standard Identification Number (ASIN) is a 10-character alphanumeric unique identifier assigned by Amazon.com and its partners for product identification within the Amazon organization (summary from Wikipedia's article). Note also that this is a definition for how to include ASINs in Schema.org data, and not a definition of ASINs in general - see documentation from Amazon for authoritative details. ASINs are most commonly encoded as text strings, but the asin property supports URL/URI as potential values too.
availabilityEnds	DateTime Time Date	The date and time after which the offered item, space, service, reward, or benefit is no longer available for use, redemption, access, pickup, or fulfillment.
availabilityStarts	Date Time DateTime	The date and time when the offered item, space, service, reward, or benefit becomes available for use, redemption, access, pickup, or fulfillment.
availabilityStatus	ItemAvailability	The current availability state of the offer, such as in stock, sold out, preorder, or limited availability.
availableAtOrFrom	Place	The place(s) from which the offer can be obtained (e.g. store locations).
availableDeliveryMethod	DeliveryMethod	The delivery method(s) available for this offer.
businessFunction	BusinessFunction	The transactional intent of an offer, such as selling, leasing, providing a service, giving something away, or raising funds.
deliveryLeadTime	QuantitativeValue	The typical delay between the receipt of the order and the goods either leaving the warehouse or being prepared for pickup, in case the delivery method is on site pickup.
eligibleCustomerType	BusinessEntityType	The type(s) of customers for which the given offer is valid.
eligibleDuration	QuantitativeValue	The duration for which the given offer is valid.
eligibleQuantity	QuantitativeValue	The interval and unit of measurement of ordering quantities for which the offer or price specification is valid. This allows e.g. specifying that a certain freight charge is valid only for a certain quantity.
eligibleRegion	Place Text GeoShape	The ISO 3166-1 (ISO 3166-1 alpha-2) or ISO 3166-2 code, the place, or the GeoShape for the geo-political region(s) for which the offer or delivery charge specification is valid.\n\nSee also ineligibleRegion.
eligibleTransactionVolume	PriceSpecification	The transaction volume, in a monetary unit, for which the offer or price specification is valid, e.g. for indicating a minimal purchasing volume, to express free shipping above a certain order volume, or to limit the acceptance of credit cards to purchases to a certain minimal amount.
gtin	Text URL	A Global Trade Item Number (GTIN). GTINs identify trade items, including products and services, using numeric identification codes. The GS1 digital link specifications express GTINs as URLs (URIs, IRIs, etc.). Details including regular expression examples can be found in, Section 6 of the GS1 URI Syntax specification; see also schema.org tracking issue for schema.org-specific discussion. A correct gtin value should be a valid GTIN, which means that it should be an all-numeric string of either 8, 12, 13 or 14 digits, or a "GS1 Digital Link" URL based on such a string. The numeric component should also have a valid GS1 check digit and meet the other rules for valid GTINs. See also GS1's GTIN Summary and Wikipedia for more details. Left-padding of the gtin values is not required or encouraged. The gtin property generalizes the earlier gtin8, gtin12, gtin13, and gtin14 properties. Note also that this is a definition for how to include GTINs in Schema.org data, and not a definition of GTINs in general - see the GS1 documentation for authoritative details.
gtin12	Text	The GTIN-12 code of the product, or the product to which the offer refers. The GTIN-12 is the 12-digit GS1 Identification Key composed of a U.P.C. Company Prefix, Item Reference, and Check Digit used to identify trade items. See GS1 GTIN Summary for more details.
gtin13	Text	The GTIN-13 code of the product, or the product to which the offer refers. This is equivalent to 13-digit ISBN codes and EAN UCC-13. Former 12-digit UPC codes can be converted into a GTIN-13 code by simply adding a preceding zero. See GS1 GTIN Summary for more details.
gtin14	Text	The GTIN-14 code of the product, or the product to which the offer refers. See GS1 GTIN Summary for more details.
gtin8	Text	The GTIN-8 code of the product, or the product to which the offer refers. This code is also known as EAN/UCC-8 or 8-digit EAN. See GS1 GTIN Summary for more details.
includesObject	TypeAndQuantityNode	This links to a node or nodes indicating the exact quantity of the products included in an Offer or ProductCollection.
ineligibleRegion	Place GeoShape Text	The ISO 3166-1 (ISO 3166-1 alpha-2) or ISO 3166-2 code, the place, or the GeoShape for the geo-political region(s) for which the offer or delivery charge specification is not valid, e.g. a region where the transaction is not allowed.\n\nSee also eligibleRegion.
inventoryLevel	QuantitativeValue	The current approximate inventory level for the offer, such as remaining seats, units, passes, or simple bookable capacity.
itemCondition	OfferItemCondition	A predefined value from OfferItemCondition specifying the condition of the product or service, or the products or services included in the offer. Also used for product return policies to specify the condition of products accepted for returns.
itemOffered	Accommodation AggregateOffer CreativeWork EducationalOccupationalProgram Event Fundraiser JobPosting MenuItem Product Service Trip	An item being offered (or demanded). The transactional nature of the offer or demand is documented using businessFunction, e.g. sell, lease etc. While several common expected types are listed explicitly in this definition, others can be used. Using a second type, such as Product or a subtype of Product, can clarify the nature of the offer.
mpn	Text	The Manufacturer Part Number (MPN) of the product, or the product to which the offer refers.
priceSpecification	PriceSpecification	One or more detailed price specifications, indicating the unit price and delivery or payment charges.
seller	Organization Person	An entity which offers (sells / leases / lends / loans) the services / goods. A seller may also be a provider.
serialNumber	Text	The serial number or any alphanumeric identifier of a particular product. When attached to an offer, it is a shortcut for the serial number of the product included in the offer.
sku	Text	The Stock Keeping Unit (SKU), i.e. a merchant-specific identifier for a product or service, or the product to which the offer refers.
validFrom	Date DateTime	The date and time when an offer, price, policy scope, recognition assertion, regulatory applicability claim, financial incentive, permit, agreement, or similar validity-bound item becomes valid, available, or applicable.

Properties from Thing

Property	Expected Type	description
additionalType	URL	An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax.

Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.

image	URL ImageObject	An image of the item. This can be a URL or a fully described ImageObject.
