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](https://en.wikipedia.org/wiki/Amazon_Standard_Identification_Number)'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.

A color swatch image, visualizing the color of a [Product](https://schema.org/Product). Should match the textual description specified in the [color](https://schema.org/color) property. This can be a URL or a fully described ImageObject.

The place where the product was assembled.

The place where the item (typically [Product](https://schema.org/Product)) was last processed and tested before importation.

The country of origin of something, including products as well as creative works such as movie and TV content. In the case of TV and movie, this would be the country of the principle offices of the production company or individual responsible for the movie. For other kinds of [CreativeWork](https://schema.org/CreativeWork) it is difficult to provide fully general guidance, and properties such as [contentLocation](https://schema.org/contentLocation) and [locationCreated](https://schema.org/locationCreated) may be more applicable. In the case of products, the country of origin of the product. The exact interpretation of this may vary by context and product type, and cannot be fully enumerated here.

The location at which an item can be viewed or experienced in-person.

A [Grant](https://schema.org/Grant) that directly or indirectly provide funding or sponsorship for this item. See also [ownershipFundingInfo](https://schema.org/ownershipFundingInfo).

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](https://schema.org/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](https://schema.org/gtin) property generalizes the earlier [gtin8](https://schema.org/gtin8), [gtin12](https://schema.org/gtin12), [gtin13](https://schema.org/gtin13), and [gtin14](https://schema.org/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](https://schema.org/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.

Used to tag an item to be intended or suitable for consumption or use by adults only.

Certification information about a product, organization, service, place, or person.

Defines the energy efficiency Category (also known as "class" or "rating") for a product according to an international energy efficiency standard.

The [GS1 digital link](https://www.gs1.org/standards/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](https://schema.org/Product) or an [Organization](https://schema.org/Organization), and for the correct granularity. In particular, for products: - A Digital Link that contains a serial number (AI `21`) should only be present on instances of [IndividualProduct](https://schema.org/IndividualProduct) - A Digital Link that contains a lot number (AI `10`) should be annotated as [SomeProducts](https://schema.org/SomeProducts) if only products from that lot are sold, or [IndividualProduct](https://schema.org/IndividualProduct) if there is only a specific product. - A Digital Link that contains a global model number (AI `8013`) should be attached to a [Product](https://schema.org/Product) or a [ProductModel](https://schema.org/ProductModel). Other item types should be adapted similarly.

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.

Specifies a MerchantReturnPolicy that may be applicable.

Indicates a ProductReturnPolicy that may be applicable.

Indicates the [productGroupID](https://schema.org/productGroupID) for a [ProductGroup](https://schema.org/ProductGroup) that this product [isVariantOf](https://schema.org/isVariantOf).

Indicates whether this content is family friendly.

Indicates the kind of product that this is a variant of. In the case of [ProductModel](https://schema.org/ProductModel), this is a pointer (from a ProductModel) to a base product from which this product is a variant. It is safe to infer that the variant inherits all product features from the base model, unless defined locally. This is not transitive. In the case of a [ProductGroup](https://schema.org/ProductGroup), the group description also serves as a template, representing a set of Products that vary on explicitly defined, specific dimensions only (so it defines both a set of variants, as well as which values distinguish amongst those variants). When used with [ProductGroup](https://schema.org/ProductGroup), this property can apply to any [Product](https://schema.org/Product) included in the group.

Keywords or tags used to describe some item. Multiple textual entries in a keywords list are typically delimited by commas, or by repeating the property.

The [mobileUrl](https://schema.org/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](https://schema.org/Product) and [Offer](https://schema.org/Offer), rather than [Thing](https://schema.org/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](https://schema.org/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](https://schema.org/url) markup to use [mobileUrl](https://schema.org/mobileUrl) for more mobile-oriented pages. The property is intended for the case when items (primarily [Product](https://schema.org/Product) and [Offer](https://schema.org/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.

Provides negative considerations regarding something, most typically in pro/con lists for reviews (alongside [positiveNotes](https://schema.org/positiveNotes)). For symmetry In the case of a [Review](https://schema.org/Review), the property describes the [itemReviewed](https://schema.org/itemReviewed) from the perspective of the review; in the case of a [Product](https://schema.org/Product), the product itself is being described. Since product descriptions tend to emphasise positive claims, it may be relatively unusual to find [negativeNotes](https://schema.org/negativeNotes) used in this way. Nevertheless for the sake of symmetry, [negativeNotes](https://schema.org/negativeNotes) can be used on [Product](https://schema.org/Product). The property values can be expressed either as unstructured text (repeated as necessary), or if ordered, as a list (in which case the most negative is at the beginning of the list).

Indicates the [NATO stock number](https://en.wikipedia.org/wiki/NATO_Stock_Number) (nsn) of a [Product](https://schema.org/Product).

A person or organization who owns this Thing.

A pattern that something has, for example 'polka dot', 'striped', 'Canadian flag'. Values are typically expressed as text, although links to controlled value schemes are also supported.

Provides positive considerations regarding something, for example product highlights or (alongside [negativeNotes](https://schema.org/negativeNotes)) pro/con lists for reviews. In the case of a [Review](https://schema.org/Review), the property describes the [itemReviewed](https://schema.org/itemReviewed) from the perspective of the review; in the case of a [Product](https://schema.org/Product), the product itself is being described. The property values can be expressed either as unstructured text (repeated as necessary), or if ordered, as a list (in which case the most positive is at the beginning of the list).

A standardized size of a product or creative work, specified either through a simple textual string (for example 'XL', '32Wx34L'), a QuantitativeValue with a unitCode, or a comprehensive and structured [SizeSpecification](https://schema.org/SizeSpecification); in other cases, the [width](https://schema.org/width), [height](https://schema.org/height), [depth](https://schema.org/depth) and [weight](https://schema.org/weight) properties may be more applicable.

A slogan or motto associated with the item.

A CreativeWork or Event about this Thing.

The identifier property represents any kind of identifier for any kind of [Thing](https://schema.org/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](https://schema.org/docs/datamodel.html#identifierBg) for more details.

The weight of the product or person.

The width of the item.
