Description Usage Arguments Value

A monetary value or range. This type can be used to describe an amount of money such as $50 USD, or a range as in describing a bank account being suitable for a balance between £1,000 and £1,000,000 GBP, or the value of a salary, etc. It is recommended to use [[PriceSpecification]] Types to describe the price of an Offer, Invoice, etc.

`id`	identifier for the object (URI)
`value`	(Text or StructuredValue or Number or Boolean or Text or StructuredValue or Number or Boolean or Text or StructuredValue or Number or Boolean type.) The value of the quantitative value or property value node.* For [[QuantitativeValue]] and [[MonetaryAmount]], the recommended type for values is 'Number'.* For [[PropertyValue]], it can be 'Text;', 'Number', 'Boolean', or 'StructuredValue'.
`validThrough`	(DateTime or DateTime or DateTime or DateTime or DateTime or DateTime or DateTime type.) The date after when the item is not valid. For example the end of an offer, salary period, or a period of opening hours.
`validFrom`	(DateTime or DateTime or DateTime or DateTime or DateTime or DateTime or DateTime type.) The date when the item becomes valid.
`minValue`	(Number or Number or Number or Number type.) The lower value of some characteristic or property.
`maxValue`	(Number or Number or Number or Number type.) The upper value of some characteristic or property.
`currency`	(Text or Text type.) The currency in which the monetary amount is expressed.Use 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 Tradings Systems](https://en.wikipedia.org/wiki/Local_exchange_trading_system) (LETS) and other currency types e.g. "Ithaca HOUR".
`url`	(URL type.) URL of the item.
`sameAs`	(URL type.) 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.
`potentialAction`	(Action type.) Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
`name`	(Text type.) The name of the item.
`mainEntityOfPage`	(URL or CreativeWork type.) 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.
`image`	(URL or ImageObject type.) An image of the item. This can be a [[URL]] or a fully described [[ImageObject]].
`identifier`	(URL or Text or PropertyValue type.) 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.
`disambiguatingDescription`	(Text type.) 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.
`description`	(Text type.) A description of the item.
`alternateName`	(Text type.) An alias for the item.
`additionalType`	(URL type.) 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.
