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.

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.

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

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

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

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.

Indicates whether this content is family friendly.

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).

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).

Indicates a page or other link involved in archival of a [CreativeWork](https://schema.org/CreativeWork). In the case of [MediaReview](https://schema.org/MediaReview), the items in a [MediaReviewItem](https://schema.org/MediaReviewItem) may often become inaccessible, but be archived by archival, journalistic, activist, or law enforcement organizations. In such cases, the referenced page may not directly publish the content.

Text of a notice appropriate for describing the copyright aspects of this Creative Work, ideally indicating the owner of the copyright for the Work.

Text that can be used to credit person(s) and/or organization(s) associated with a published Creative Work.

Used to indicate a specific claim contained, implied, translated or refined from the content of a [MediaObject](https://schema.org/MediaObject) or other [CreativeWork](https://schema.org/CreativeWork).

Thumbnail image for an image or video.

Indicates the primary entity described in some page or other CreativeWork.

Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See [background notes](https://schema.org/docs/datamodel.html#mainEntityBackground) for details.

A maintainer of a [Dataset](https://schema.org/Dataset), software package ([SoftwareApplication](https://schema.org/SoftwareApplication)), or other [Project](https://schema.org/Project). A maintainer is a [Person](https://schema.org/Person) or [Organization](https://schema.org/Organization) that manages contributions to, and/or publication of, some (typically complex) artifact. It is common for distributions of software and data to be based on "upstream" sources. When [maintainer](https://schema.org/maintainer) is applied to a specific version of something e.g. a particular version or packaging of a [Dataset](https://schema.org/Dataset), it is always possible that the upstream source has a different maintainer. The [isBasedOn](https://schema.org/isBasedOn) property can be used to indicate such relationships between datasets to make the different maintenance roles clear. Similarly in the case of software, a package may have dedicated maintainers working on integration into software distributions such as Ubuntu, as well as upstream maintainers of the underlying work.

The manufacturer of the product.

A material that something is made from, e.g. leather, wool, cotton, paper.

The quantity of the materials being described or an expression of the physical space they occupy.

Indicates that the CreativeWork contains a reference to, but is not necessarily about a concept.

The name of the item.

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

An offer to provide this item—for example, an offer to sell a product, rent the DVD of a movie, perform a service, or give away tickets to an event. Use [businessFunction](https://schema.org/businessFunction) to indicate the kind of transaction offered, i.e. sell, lease, etc. This property can also be used to describe a [Demand](https://schema.org/Demand). While this property is listed as expected on a number of common types, it can be used in others. In that case, using a second type, such as Product or a subtype of Product, can clarify the nature of the offer.

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.

The position of an item in a series or sequence of items.

Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.

The publishingPrinciples property indicates (typically via [URL](https://schema.org/URL)) a document describing the editorial principles of an [Organization](https://schema.org/Organization) (or individual, e.g. a [Person](https://schema.org/Person) writing a blog) that relate to their activities as a publisher, e.g. ethics or diversity policies. When applied to a [CreativeWork](https://schema.org/CreativeWork) (e.g. [NewsArticle](https://schema.org/NewsArticle)) the principles are those of the party primarily responsible for the creation of the [CreativeWork](https://schema.org/CreativeWork). While such policies are most typically expressed in natural language, sometimes related information (e.g. indicating a [funder](https://schema.org/funder)) can be expressed using schema.org terminology.

The date the item, e.g. vehicle, was purchased by the current owner.

The Event where the CreativeWork was recorded. The CreativeWork may capture all or part of the event.

The release date of a product or product model. This can be used to distinguish the exact variant of a product.

The place and time the release was issued, expressed as a PublicationEvent.

A review of the item.

Review of the item.

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.

Indicates (by URL or string) a particular version of a schema used in some CreativeWork. This property was created primarily to indicate the use of a specific schema.org release, e.g. `10.0` as a simple string, or more explicitly via URL, `https://schema.org/docs/releases.html#v10.0`. There may be situations in which other schemas might usefully be referenced this way, e.g. `http://dublincore.org/specifications/dublin-core/dces/1999-07-02/` but this has not been carefully explored in the community.

Indicates the date on which the current structured data was generated / published. Typically used alongside [sdPublisher](https://schema.org/sdPublisher).

A license document that applies to this structured data, typically indicated by URL.

Indicates the party responsible for generating and publishing the current structured data markup, typically in cases where the structured data is derived automatically from existing published content but published on a different site. For example, student projects and open data initiatives often re-publish existing content with more explicitly structured metadata. The [sdPublisher](https://schema.org/sdPublisher) property helps make such practices more explicit.

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.

The Stock Keeping Unit (SKU), i.e. a merchant-specific identifier for a product or service, or the product to which the offer refers.

A slogan or motto associated with the item.

The Organization on whose behalf the creator was working.

The "spatial" property can be used in cases when more specific properties (e.g. [locationCreated](https://schema.org/locationCreated), [spatialCoverage](https://schema.org/spatialCoverage), [contentLocation](https://schema.org/contentLocation)) are not known to be appropriate.

The spatialCoverage of a CreativeWork indicates the place(s) which are the focus of the content. It is a subproperty of contentLocation intended primarily for more technical and detailed materials. For example with a Dataset, it indicates areas that the dataset describes: a dataset of New York weather would have spatialCoverage which was the place: the state of New York.

A person or organization that supports a thing through a pledge, promise, or financial contribution. E.g. a sponsor of a Medical Study or a corporate sponsor of an event.

A CreativeWork or Event about this Thing.

The item being described is intended to help a person learn the competency or learning outcome defined by the referenced term.

The "temporal" property can be used in cases where more specific properties (e.g. [temporalCoverage](https://schema.org/temporalCoverage), [dateCreated](https://schema.org/dateCreated), [dateModified](https://schema.org/dateModified), [datePublished](https://schema.org/datePublished)) are not known to be appropriate.

The temporalCoverage of a CreativeWork indicates the period that the content applies to, i.e. that it describes, either as a DateTime or as a textual string indicating a time period in [ISO 8601 time interval format](https://en.wikipedia.org/wiki/ISO_8601#Time_intervals). In the case of a Dataset it will typically indicate the relevant time period in a precise notation (e.g. for a 2011 census dataset, the year 2011 would be written "2011/2012"). Other forms of content, e.g. ScholarlyArticle, Book, TVSeries or TVEpisode, may indicate their temporalCoverage in broader terms - textually or via well-known URL. Written works such as books may sometimes have precise temporal coverage too, e.g. a work set in 1939 - 1945 can be indicated in ISO 8601 interval format format via "1939/1945". Open-ended date ranges can be written with ".." in place of the end date. For example, "2015-11/.." indicates a range beginning in November 2015 and with no specified final date. This is tentative and might be updated in future when ISO 8601 is officially updated.

This property is applicable both to works that are freely available and to those that require payment or other transactions. It can reference additional information, e.g. community expectations on preferred linking and citation conventions, as well as purchasing details. For something that can be commercially licensed, usageInfo can provide detailed, resource-specific information about licensing options. This property can be used alongside the license property which indicates license(s) applicable to some piece of content. The usageInfo property can provide information about other licensing options, e.g. acquiring commercial usage rights for an image that is also available under non-commercial creative commons licenses.
