Property

Description

Properties from [AggregateRating](https://schema.org/AggregateRating "AggregateRating")

`[itemReviewed](https://schema.org/itemReviewed "itemReviewed")`

[Thing](https://schema.org/Thing "Thing")

The item that is being reviewed/rated.

`[ratingCount](https://schema.org/ratingCount "ratingCount")`

[Integer](https://schema.org/Integer "Integer")

The count of total number of ratings.

`[reviewCount](https://schema.org/reviewCount "reviewCount")`

[Integer](https://schema.org/Integer "Integer")

The count of total number of reviews.

Properties from [Rating](https://schema.org/Rating "Rating")

`[author](https://schema.org/author "author")`

[Organization](https://schema.org/Organization "Organization")  or  
[Person](https://schema.org/Person "Person")

The author of this content or rating. Please note that author is special in that HTML 5 provides a special mechanism for indicating authorship via the rel tag. That is equivalent to this and may be used interchangeably.

`[bestRating](https://schema.org/bestRating "bestRating")`

[Number](https://schema.org/Number "Number")  or  
[Text](https://schema.org/Text "Text")

The highest value allowed in this rating system.

`[ratingExplanation](https://schema.org/ratingExplanation "ratingExplanation")`

[Text](https://schema.org/Text "Text")

A short explanation (e.g. one to two sentences) providing background context and other information that led to the conclusion expressed in the rating. This is particularly applicable to ratings associated with "fact check" markup using [ClaimReview](https://schema.org/ClaimReview).

`[ratingValue](https://schema.org/ratingValue "ratingValue")`

[Number](https://schema.org/Number "Number")  or  
[Text](https://schema.org/Text "Text")

The rating for the content.

Usage guidelines:

-   Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols.
-   Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.

`[reviewAspect](https://schema.org/reviewAspect "reviewAspect")`

[StructuredValue](https://schema.org/StructuredValue "StructuredValue")  or  
[Text](https://schema.org/Text "Text")

This Review or Rating is relevant to this part or facet of the itemReviewed.

`[worstRating](https://schema.org/worstRating "worstRating")`

[Number](https://schema.org/Number "Number")  or  
[Text](https://schema.org/Text "Text")

The lowest value allowed in this rating system.

Properties from [Thing](https://schema.org/Thing "Thing")

`[additionalType](https://schema.org/additionalType "additionalType")`

[Text](https://schema.org/Text "Text")  or  
[URL](https://schema.org/URL "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. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org [style guide](https://schema.org/docs/styleguide.html).

`[alternateName](https://schema.org/alternateName "alternateName")`

[Text](https://schema.org/Text "Text")

An alias for the item.

`[description](https://schema.org/description "description")`

[Text](https://schema.org/Text "Text")  or  
[TextObject](https://schema.org/TextObject "TextObject")

A description of the item.

`[disambiguatingDescription](https://schema.org/disambiguatingDescription "disambiguatingDescription")`

[Text](https://schema.org/Text "Text")

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.

`[identifier](https://schema.org/identifier "identifier")`

[PropertyValue](https://schema.org/PropertyValue "PropertyValue")  or  
[Text](https://schema.org/Text "Text")  or  
[URL](https://schema.org/URL "URL")

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.

`[image](https://schema.org/image "image")`

[ImageObject](https://schema.org/ImageObject "ImageObject")  or

[CreativeWork](https://schema.org/CreativeWork "CreativeWork")  or  
[URL](https://schema.org/URL "URL")

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.

`[sameAs](https://schema.org/sameAs "sameAs")`

[URL](https://schema.org/URL "URL")

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.
