Rating

schema:Thing > schema:Intangible > schema:Rating

A rating is an evaluation on a numeric scale, such as 1 to 5 stars.

Property	Expected Type	Description
Properties from schema:Rating
`schema:bestRating`	schema:Number or schema:Text	The highest value allowed in this rating system. If bestRating is omitted, 5 is assumed.
`schema:ratingValue`	schema:Text	The rating for the content.
`schema:worstRating`	schema:Number or schema:Text	The lowest value allowed in this rating system. If worstRating is omitted, 1 is assumed.
Properties from schema:Thing
`schema:additionalType`	schema:URL	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.
`schema:alternateName`	schema:Text	An alias for the item.
`schema:description`	schema:Text	A short description of the item.
`schema:image`	schema:ImageObject or schema:URL	An image of the item. This can be a URL or a fully described ImageObject.
`schema:name`	schema:Text	The name of the item.
`schema:potentialAction`	schema:Action	Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
`schema:sameAs`	schema:URL	URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Freebase page, or official website.
`schema:url`	schema:URL	URL of the item.

Instances of schema:Rating may appear as values for the following properties

Property	On Types	Description
`schema:reviewRating`	schema:Review	The rating given in this review. Note that reviews can themselves be rated. The `reviewRating` applies to rating given by the review. The `aggregateRating` property applies to the review itself, as a creative work.
