Endorsement Rating

An EndorsementRating is a rating that expresses some level of endorsement, for example inclusion in a "critic's pick" blog, a "Like" or "+1" on a social network. It can be considered the result of an EndorseAction in which the object of the action is rated positively by some agent. As is common elsewhere in schema.org, it is sometimes more useful to describe the results of such an action without explicitly describing the Action.
An EndorsementRating may be part of a numeric scale or organized system, but this is not required: having an explicit type for indicating a positive, endorsement rating is particularly useful in the absence of numeric scales as it helps consumers understand that the rating is broadly positive.

Properties from Rating

Property	Expected Type	description
author	Organization 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	Text Number	The highest value allowed in this rating system. If bestRating is omitted, 5 is assumed.
ratingExplanation	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.
ratingSource	Text	The source provider who the ratings were conducted by. For example, google or tmpc.
ratingValue	Number Text	The rating for the content.\n\nUsage guidelines:\n\n Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols.\n Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.
reviewAspect	Text	This Review or Rating is relevant to this part or facet of the itemReviewed.
worstRating	Text Number	The lowest value allowed in this rating system. If worstRating is omitted, 1 is assumed.

Properties from Thing

Property	Expected Type	description
additionalType	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.
alternateName	Text	An alias for the item.
description	Text	A description of the item.
disambiguatingDescription	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	PropertyValue URL Text	The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc.
image	URL ImageObject	An image of the item. This can be a URL or a fully described ImageObject.
instanceOf	Enumeration	Type to which this subject belongs. Use for membership in a value set (Enumeration), not inheritance. Example: K2 instanceOf mountain; volcano subClassOf mountain.
mainEntityOfPage	URL CreativeWork	Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.
name	Text	The name of the item.
potentialAction	Action	Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
sameAs	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.
subjectOf	Event CreativeWork	A CreativeWork or Event about this Thing.
url	URL	URL of the item.
