PropertyValue

Thing > Intangible > StructuredValue > PropertyValue

A property-value pair, e.g. representing a feature of a product or place. Use the 'name' property for the name of the property. If there is an additional human-readable version of the value, put that into the 'description' property.

Always use specific schema.org properties when a) they exist and b) you can populate them. Using PropertyValue as a substitute will typically not trigger the same effect as using the original, specific property.

PropertyExpected TypeDescription
Properties from PropertyValue
maxValue Number The upper value of some characteristic or property.
minValue Number The lower value of some characteristic or property.
propertyID Text  or
URL 
A commonly used identifier for the characteristic represented by the property, e.g. a manufacturer or a standard code for a property. propertyID can be (1) a prefixed string, mainly meant to be used with standards for product properties; (2) a site-specific, non-prefixed string (e.g. the primary key of the property or the vendor-specific id of the property), or (3) a URL indicating the type of the property, either pointing to an external vocabulary, or a Web resource that describes the property (e.g. a glossary entry). Standards bodies should promote a standard prefix for the identifiers of properties from their standards.
unitCode Text  or
URL 
The unit of measurement given using the UN/CEFACT Common Code (3 characters) or a URL. Other codes than the UN/CEFACT Common Code may be used with a prefix followed by a colon.
unitText Text A string or text indicating the unit of measurement. Useful if you cannot provide a standard unit code for unitCode.
value Boolean  or
Number  or
StructuredValue  or
Text 
The value of the quantitative value or property value node.
For QuantitativeValue and MonetaryValue, the recommended type for values is 'Number'.
For PropertyValue, it can be 'Text;', 'Number', 'Boolean', or 'StructuredValue'.
valueReference Enumeration  or
PropertyValue  or
QualitativeValue  or
QuantitativeValue  or
StructuredValue 
A pointer to a secondary value that provides additional information on the original value, e.g. a reference temperature.
Properties from Thing
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.
image ImageObject  or
URL 
An image of the item. This can be a URL or a fully described ImageObject.
mainEntityOfPage CreativeWork  or
URL 
Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.
Inverse property: mainEntity.
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, Freebase page, or official website.
url URL URL of the item.


Instances of PropertyValue may appear as values for the following properties
PropertyOn TypesDescription
additionalProperty Place  or
Product  or
QualitativeValue  or
QuantitativeValue 
A property-value pair representing an additional characteristics of the entitity, 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. http://schema.org/width, http://schema.org/color, http://schema.org/gtin13, ...) will typically expect such data to be provided using those properties, rather than using the generic property/value mechanism.

exifData ImageObject exif data for this object.
valueReference PropertyValue  or
QualitativeValue  or
QuantitativeValue 
A pointer to a secondary value that provides additional information on the original value, e.g. a reference temperature.
