| additionalProperty | A property-value pair representing an additional characteristic of the entity, e.g. a product feature or another characteristic for which there is no matching property in schema.org.\n\nNote: Publishers should be aware that applications designed to use specific schema.org properties (e.g. https://schema.org/width, https://schema.org/color, https://schema.org/gtin13, ...) will typically expect such data to be provided using those properties, rather than using the generic property/value mechanism. | PropertyValue |
| itemCondition | 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. | OfferItemCondition |

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. | Text, URL |
| review | A review of the item. | Review |
| isFamilyFriendly | Indicates whether this content is family friendly. | Boolean |
| gtin13 | 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](http://www.gs1.org/barcodes/technical/idkeys/gtin) for more details. | Text |
| hasMerchantReturnPolicy | Specifies a MerchantReturnPolicy that may be applicable. | MerchantReturnPolicy |
| priceCurrency | The currency of the price, or a price component when attached to [[PriceSpecification]] and its subtypes.\n\nUse standard formats: [ISO 4217 currency format](http://en.wikipedia.org/wiki/ISO_4217), e.g. "USD"; [Ticker symbol](https://en.wikipedia.org/wiki/List_of_cryptocurrencies) for cryptocurrencies, e.g. "BTC"; well known names for [Local Exchange Trading Systems](https://en.wikipedia.org/wiki/Local_exchange_trading_system) (LETS) and other currency types, e.g. "Ithaca HOUR". | Text |
| eligibleRegion | 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]]. | Place, Text, GeoShape |
| eligibleTransactionVolume | 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. | PriceSpecification |
| hasGS1DigitalLink | The GS1 digital link associated with the object. This URL should conform to the particular requirements of digital links. The link should only contain the Application Identifiers (AIs) that are relevant for the entity being annotated, for instance a [[Product]] or an [[Organization]], and for the correct granularity. In particular, for products:
| URL |
| acceptedPaymentMethod | The payment method(s) that are accepted in general by an organization, or for some specific demand or offer. | PaymentMethod, LoanOrCredit, Text |
| gtin14 | The GTIN-14 code of the product, or the product to which the offer refers. See [GS1 GTIN Summary](http://www.gs1.org/barcodes/technical/idkeys/gtin) for more details. | Text |
| mobileUrl | 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](https://en.wikipedia.org/wiki/Responsive_web_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. | Text |
| itemOffered | 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. | MenuItem, Trip, Event, CreativeWork, Product, Service, AggregateOffer |
| priceValidUntil | The date after which the price is no longer available. | Date |
| validFrom | The date when the item becomes valid. | DateTime, Date |
| aggregateRating | The overall rating, based on a collection of reviews or ratings, of the item. | AggregateRating |
| availabilityStarts | The beginning of the availability of the product or service included in the offer. | Date, DateTime, Time |
| price | The offer price of a product, or of a price component when attached to PriceSpecification and its subtypes.\n\nUsage guidelines:\n\n* Use the [[priceCurrency]] property (with standard formats: [ISO 4217 currency format](http://en.wikipedia.org/wiki/ISO_4217), e.g. "USD"; [Ticker symbol](https://en.wikipedia.org/wiki/List_of_cryptocurrencies) for cryptocurrencies, e.g. "BTC"; well known names for [Local Exchange Trading Systems](https://en.wikipedia.org/wiki/Local_exchange_trading_system) (LETS) and other currency types, e.g. "Ithaca HOUR") instead of including [ambiguous symbols](http://en.wikipedia.org/wiki/Dollar_sign#Currencies_that_use_the_dollar_or_peso_sign) such as '$' in the value.\n* Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.\n* Note that both [RDFa](http://www.w3.org/TR/xhtml-rdfa-primer/#using-the-content-attribute) and Microdata syntax allow the use of a "content=" attribute for publishing simple machine-readable values alongside more human-friendly formatting.\n* Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols. | Text, Number |
| availableDeliveryMethod | The delivery method(s) available for this offer. | DeliveryMethod |
| eligibleQuantity | 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. | QuantitativeValue |
| gtin | A Global Trade Item Number ([GTIN](https://www.gs1.org/standards/id-keys/gtin)). GTINs identify trade items, including products and services, using numeric identification codes. 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](https://www.gs1.org/services/check-digit-calculator) and meet the other rules for valid GTINs. See also [GS1's GTIN Summary](http://www.gs1.org/barcodes/technical/idkeys/gtin) and [Wikipedia](https://en.wikipedia.org/wiki/Global_Trade_Item_Number) 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. The GS1 [digital link specifications](https://www.gs1.org/standards/Digital-Link/) expresses GTINs as URLs (URIs, IRIs, etc.). Digital Links should be populated into the [[hasGS1DigitalLink]] attribute. 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. | Text, URL |
| seller | An entity which offers (sells / leases / lends / loans) the services / goods. A seller may also be a provider. | Person, Organization |
| availabilityEnds | The end of the availability of the product or service included in the offer. | DateTime, Time, Date |

| hasAdultConsideration | Used to tag an item to be intended or suitable for consumption or use by adults only. | AdultOrientedEnumeration |
| hasMeasurement | A measurement of an item, For example, the inseam of pants, the wheel size of a bicycle, the gauge of a screw, or the carbon footprint measured for certification by an authority. Usually an exact measurement, but can also be a range of measurements for adjustable products, for example belts and ski bindings. | QuantitativeValue |
| areaServed | The geographic area where a service or offered item is provided. | GeoShape, AdministrativeArea, Place, Text |
| includesObject | This links to a node or nodes indicating the exact quantity of the products included in an [[Offer]] or [[ProductCollection]]. | TypeAndQuantityNode |
| Property | Description | Range |
|---|---|---|
| potentialAction | Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role. | Action |
| image | An image of the item. This can be a [[URL]] or a fully described [[ImageObject]]. | URL, ImageObject |
| sameAs | URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website. | URL |

| additionalType | 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. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org style guide. | Text, URL |
| disambiguatingDescription | 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. | Text |
| alternateName | An alias for the item. | Text |
| name | The name of the item. | Text |
| identifier | 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](/docs/datamodel.html#identifierBg) for more details. | Text, URL, PropertyValue |
| mainEntityOfPage | Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See [background notes](/docs/datamodel.html#mainEntityBackground) for details. | CreativeWork, URL |
