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 it is difficult to provide fully general guidance, and properties such as contentLocation and 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.
`creativeWorkStatus`	DefinedTerm or Text	The status of a creative work in terms of its stage in a lifecycle. Example terms include Incomplete, Draft, Published, Obsolete. Some organizations define a set of terms for the stages of their publication lifecycle.

Since schema.org types like Movie and TVEpisode can be used for both works and their multiple expressions, it is possible to use titleEIDR alone (for a general description), or alongside editEIDR for a more edit-specific description.
`editor`	Person	Specifies the Person who edited the CreativeWork.
`educationalAlignment`	AlignmentObject	An alignment to an established educational framework. This property should not be used where the nature of the alignment can be described using a simple property, for example to express that a resource teaches or assesses a competency.

`exampleOfWork`	CreativeWork	A creative work that this work is an example/instance/realization/derivation of. Inverse property: workExample
`expires`	Date or DateTime	Date the content expires and is no longer useful or available. For example a VideoObject or NewsArticle whose availability or relevance is time-limited, a ClaimReview fact check whose publisher wants to indicate that it may no longer be relevant (or helpful to highlight) after some date, or a Certification the validity has expired.

`mainEntity`	Thing	Indicates the primary entity described in some page or other CreativeWork. Inverse property: mainEntityOfPage
`maintainer`	Organization or Person	A maintainer of a Dataset, software package (SoftwareApplication), or other Project. A maintainer is a Person or 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 is applied to a specific version of something e.g. a particular version or packaging of a Dataset, it is always possible that the upstream source has a different maintainer. The 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.
`material`	Product or Text or URL	A material that something is made from, e.g. leather, wool, cotton, paper.
`materialExtent`	QuantitativeValue or Text	The quantity of the materials being described or an expression of the physical space they occupy.
`mentions`	Thing	Indicates that the CreativeWork contains a reference to, but is not necessarily about a concept.
`offers`	Demand or Offer	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 to indicate the kind of transaction offered, i.e. sell, lease, etc. This property can also be used to describe a 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. Inverse property: itemOffered
`pattern`	DefinedTerm or Text	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.
`position`	Integer or Text	The position of an item in a series or sequence of items.
`producer`	Organization or Person	The person or organization who produced the work (e.g. music album, movie, TV/radio series etc.).
`provider`	Organization or Person	The service provider, service operator, or service performer; the goods producer. Another party (a seller) may offer those services or goods on behalf of the provider. A provider may also serve as the seller. Supersedes carrier.
`publication`	PublicationEvent	A publication event associated with the item.
`publisher`	Organization or Person	The publisher of the creative work.
`publisherImprint`	Organization	The publishing division which published the comic.
`publishingPrinciples`	CreativeWork or URL	The publishingPrinciples property indicates (typically via URL) a document describing the editorial principles of an Organization (or individual, e.g. a Person writing a blog) that relate to their activities as a publisher, e.g. ethics or diversity policies. When applied to a CreativeWork (e.g. NewsArticle) the principles are those of the party primarily responsible for the creation of the CreativeWork. While such policies are most typically expressed in natural language, sometimes related information (e.g. indicating a funder) can be expressed using schema.org terminology.
`recordedAt`	Event	The Event where the CreativeWork was recorded. The CreativeWork may capture all or part of the event. Inverse property: recordedIn
`releasedEvent`	PublicationEvent	The place and time the release was issued, expressed as a PublicationEvent.
`review`	Review	A review of the item. Supersedes reviews.
`schemaVersion`	Text or URL	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.
`sdDatePublished`	Date	Indicates the date on which the current structured data was generated / published. Typically used alongside sdPublisher.
`sdLicense`	CreativeWork or URL	A license document that applies to this structured data, typically indicated by URL.
`sdPublisher`	Organization or Person	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 property helps make such practices more explicit.
`size`	DefinedTerm or QuantitativeValue or SizeSpecification or Text	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; in other cases, the width, height, depth and weight properties may be more applicable.
`sourceOrganization`	Organization	The Organization on whose behalf the creator was working.
`spatial`	Place	The "spatial" property can be used in cases when more specific properties (e.g. locationCreated, spatialCoverage, contentLocation) are not known to be appropriate.
`spatialCoverage`	Place	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.
`sponsor`	Organization or Person	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.
`teaches`	DefinedTerm or Text	The item being described is intended to help a person learn the competency or learning outcome defined by the referenced term.
`temporal`	DateTime or Text	The "temporal" property can be used in cases where more specific properties (e.g. temporalCoverage, dateCreated, dateModified, datePublished) are not known to be appropriate.
`temporalCoverage`	DateTime or Text or URL	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. 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. Supersedes datasetTimeInterval.
`text`	Text	The textual content of this CreativeWork.
`thumbnail`	ImageObject	Thumbnail image for an image or video.
`thumbnailUrl`	URL	A thumbnail image relevant to the Thing.
`timeRequired`	Duration	Approximate or typical time it usually takes to work with or through the content of this work for the typical or target audience.
`translationOfWork`	CreativeWork	The work that this work has been translated from. E.g. 物种起源 is a translationOf “On the Origin of Species”. Inverse property: workTranslation
`translator`	Organization or Person	Organization or person who adapts a creative work to different languages, regional differences and technical requirements of a target market, or that translates during some event.
`typicalAgeRange`	Text	The typical expected age range, e.g. '7-9', '11-'.
`usageInfo`	CreativeWork or URL	The schema.org usageInfo property indicates further information about a CreativeWork. 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.
`version`	Number or Text	The version of the CreativeWork embodied by a specified resource.
`video`	Clip or VideoObject	An embedded video object.
`workExample`	CreativeWork	Example/instance/realization/derivation of the concept of this creative work. E.g. the paperback edition, first edition, or e-book. Inverse property: exampleOfWork
`workTranslation`	CreativeWork	A work that is a translation of the content of this work. E.g. 西遊記 has an English workTranslation “Journey to the West”, a German workTranslation “Monkeys Pilgerfahrt” and a Vietnamese translation Tây du ký bình khảo. Inverse property: translationOfWork
Properties from Product
`additionalProperty`	PropertyValue	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. Note: 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.
`aggregateRating`	AggregateRating	The overall rating, based on a collection of reviews or ratings, of the item.
`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.
`audience`	Audience	An intended audience, i.e. a group for whom something was created. Supersedes serviceAudience.
`award`	Text	An award won by or for this item. Supersedes awards.
`brand`	Brand or Organization	The brand(s) associated with a product or service, or the brand(s) maintained by an organization or business person.
`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.
`color`	Text	The color of the product.
`colorSwatch`	ImageObject or URL	A color swatch image, visualizing the color of a Product. Should match the textual description specified in the color property. This can be a URL or a fully described ImageObject.

`countryOfLastProcessing`	Text	The place where the item (typically Product) was last processed and tested before importation.
`countryOfOrigin`	Country	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 it is difficult to provide fully general guidance, and properties such as contentLocation and 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.
`depth`	Distance or QuantitativeValue	The depth of the item.
`funding`	Grant	A Grant that directly or indirectly provide funding or sponsorship for this item. See also ownershipFundingInfo. Inverse property: fundedItem
`gtin`	Text or URL	A Global Trade Item Number (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 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. The GS1 digital link specifications 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.
`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.
`hasCertification`	Certification	Certification information about a product, organization, service, place, or person.
`hasEnergyConsumptionDetails`	EnergyConsumptionDetails	Defines the energy efficiency Category (also known as "class" or "rating") for a product according to an international energy efficiency standard.
`hasGS1DigitalLink`	URL	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: A Digital Link that contains a serial number (AI `21`) should only be present on instances of IndividualProduct A Digital Link that contains a lot number (AI `10`) should be annotated as SomeProduct if only products from that lot are sold, or 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 or a ProductModel. Other item types should be adapted similarly.
`hasMeasurement`	QuantitativeValue	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.
`hasMerchantReturnPolicy`	MerchantReturnPolicy	Specifies a MerchantReturnPolicy that may be applicable. Supersedes hasProductReturnPolicy.
`height`	Distance or QuantitativeValue	The height of the item.
`inProductGroupWithID`	Text	Indicates the productGroupID for a ProductGroup that this product isVariantOf.
`isAccessoryOrSparePartFor`	Product	A pointer to another product (or multiple products) for which this product is an accessory or spare part.
`isConsumableFor`	Product	A pointer to another product (or multiple products) for which this product is a consumable.
`isFamilyFriendly`	Boolean	Indicates whether this content is family friendly.
`isRelatedTo`	Product or Service	A pointer to another, somehow related product (or multiple products).
`isSimilarTo`	Product or Service	A pointer to another, functionally similar product (or multiple products).
`isVariantOf`	ProductGroup or ProductModel	Indicates the kind of product that this is a variant of. In the case of 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, 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, this property can apply to any Product included in the group. Inverse property: hasVariant
`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.
`keywords`	DefinedTerm or Text or URL	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.
`logo`	ImageObject or URL	An associated logo.
`manufacturer`	Organization	The manufacturer of the product.
`material`	Product or Text or URL	A material that something is made from, e.g. leather, wool, cotton, paper.
`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.
`model`	ProductModel or Text	The model of the product. Use with the URL of a ProductModel or a textual representation of the model identifier. The URL of the ProductModel can be from an external source. It is recommended to additionally provide strong product identifiers via the gtin8/gtin13/gtin14 and mpn properties.
`mpn`	Text	The Manufacturer Part Number (MPN) of the product, or the product to which the offer refers.
`negativeNotes`	ItemList or ListItem or Text or WebContent	Provides negative considerations regarding something, most typically in pro/con lists for reviews (alongside positiveNotes). For symmetry In the case of a Review, the property describes the itemReviewed from the perspective of the review; in the case of a Product, the product itself is being described. Since product descriptions tend to emphasise positive claims, it may be relatively unusual to find negativeNotes used in this way. Nevertheless for the sake of symmetry, negativeNotes can be used on 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).
`nsn`	Text	Indicates the NATO stock number (nsn) of a Product.
`offers`	Demand or Offer	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 to indicate the kind of transaction offered, i.e. sell, lease, etc. This property can also be used to describe a 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. Inverse property: itemOffered
`pattern`	DefinedTerm or Text	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.
`positiveNotes`	ItemList or ListItem or Text or WebContent	Provides positive considerations regarding something, for example product highlights or (alongside negativeNotes) pro/con lists for reviews. In the case of a Review, the property describes the itemReviewed from the perspective of the review; in the case of a 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).
`productID`	Text	The product identifier, such as ISBN. For example: `meta itemprop="productID" content="isbn:123-456-789"`.
