OfferForPurchase

A Schema.org Type

This term is proposed for full integration into Schema.org, pending implementation feedback and adoption from applications and websites.
An OfferForPurchase in Schema.org represents an Offer to sell something, i.e. an Offer whose businessFunction is sell. See Good Relations for background on the underlying concepts.
PropertyExpected TypeDescription
Properties from Offer
acceptedPaymentMethod LoanOrCredit  or
PaymentMethod
The payment method(s) accepted by seller for this offer.
addOn Offer An additional offer that can only be obtained in combination with the first base offer (e.g. supplements and extensions that are available for a surcharge).
advanceBookingRequirement QuantitativeValue The amount of time that is required between accepting the offer and the actual usage of the resource or service.

asin Text  or
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.
availability ItemAvailability The availability of this item—for example In stock, Out of stock, Pre-order, etc.
availabilityEnds Date  or
DateTime  or
Time
The end of the availability of the product or service included in the offer.
availabilityStarts Date  or

availableDeliveryMethod DeliveryMethod The delivery method(s) available for this offer.
businessFunction BusinessFunction The business function (e.g. sell, lease, repair, dispose) of the offer or component of a bundle (TypeAndQuantityNode). The default is http://purl.org/goodrelations/v1#Sell.
category CategoryCode  or
PhysicalActivityCategory  or
Text  or
Thing  or
URL
A category for the item. Greater signs or slashes can be used to informally indicate a category hierarchy.
checkoutPageURLTemplate Text A URL template (RFC 6570) for a checkout page for an offer. This approach allows merchants to specify a URL for online checkout of the offered product, by interpolating parameters such as the logged in user ID, product ID, quantity, discount code etc. Parameter naming and standardization are not specified here.
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 GeoShape  or
Place  or
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 valid.

See 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  or
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.
hasAdultConsideration AdultOrientedEnumeration Used to tag an item to be intended or suitable for consumption or use by adults only.
hasMeasurement QuantitativeValue A product measurement, for example the inseam of pants, the wheel size of a bicycle, or the gauge of a screw. Usually an exact measurement, but can also be a range of measurements for adjustable products, for example belts and ski bindings.
hasMerchantReturnPolicy MerchantReturnPolicy Specifies a MerchantReturnPolicy that may be applicable. Supersedes hasProductReturnPolicy.
includesObject TypeAndQuantityNode This links to a node or nodes indicating the exact quantity of the products included in an Offer or ProductCollection.
ineligibleRegion GeoShape  or
Place  or
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.

See also eligibleRegion.
inventoryLevel QuantitativeValue The current approximate inventory level for the item or items.
isFamilyFriendly Boolean Indicates whether this content is family friendly.
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 AggregateOffer  or
CreativeWork  or
Event  or
MenuItem  or
Product  or
Service  or
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.
Inverse property: offers
leaseLength Duration  or
QuantitativeValue
Length of the lease for some Accommodation, either particular to some Offer or in some cases intrinsic to the property.
mobileUrl Text The mobileUrl property is provided for specific situations in which data consumers need to determine whether one of several provided URLs is a dedicated 'mobile site'.

To discourage over-use, and reflecting intial usecases, the property is expected only on Product and Offer, rather than Thing. The general trend in web technology is towards responsive design in which content can be flexibly adapted to a wide range of browsing environments. Pages and sites referenced with the long-established url property should ideally also be usable on a wide variety of devices, including mobile phones. In most cases, it would be pointless and counter productive to attempt to update all url markup to use mobileUrl for more mobile-oriented pages. The property is intended for the case when items (primarily Product and Offer) have extra URLs hosted on an additional "mobile site" alongside the main one. It should not be taken as an endorsement of this publication style.
mpn Text The Manufacturer Part Number (MPN) of the product, or the product to which the offer refers.
offeredBy Organization  or
Person
A pointer to the organization or person making the offer.
Inverse property: makesOffer
price Number  or
Text
The offer price of a product, or of a price component when attached to PriceSpecification and its subtypes.

Usage guidelines:

  • Use the priceCurrency property (with standard formats: ISO 4217 currency format, e.g. "USD"; Ticker symbol for cryptocurrencies, e.g. "BTC"; well known names for Local Exchange Trading Systems (LETS) and other currency types, e.g. "Ithaca HOUR") instead of including ambiguous symbols such as '$' in the value.
  • Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.
  • Note that both RDFa and Microdata syntax allow the use of a "content=" attribute for publishing simple machine-readable values alongside more human-friendly formatting.
  • Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols.
priceCurrency Text The currency of the price, or a price component when attached to PriceSpecification and its subtypes.

Use standard formats: ISO 4217 currency format, e.g. "USD"; Ticker symbol for cryptocurrencies, e.g. "BTC"; well known names for Local Exchange Trading Systems (LETS) and other currency types, e.g. "Ithaca HOUR".
priceSpecification PriceSpecification One or more detailed price specifications, indicating the unit price and delivery or payment charges.
priceValidUntil Date The date after which the price is no longer available.
review Review A review of the item. Supersedes reviews.
seller Organization  or
Person
An entity which offers (sells / leases / lends / loans) the services / goods. A seller may also be a provider. Supersedes merchant, vendor.
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.
shippingDetails OfferShippingDetails Indicates information about the shipping policies and options associated with an 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.

warranty WarrantyPromise The warranty promise(s) included in the offer. Supersedes warrantyPromise.
Properties from Thing
additionalType URL An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. In RDFa syntax, it is better to use the native RDFa syntax - the 'typeof' attribute - for multiple types. Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.
alternateName Text An alias for the item.
description Text A description of the item.
disambiguatingDescription Text A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.
identifier PropertyValue  or
Text  or
URL
The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.
image ImageObject  or
URL
An image of the item. This can be a URL or a fully described ImageObject.
mainEntityOfPage CreativeWork  or
