PropertyValueSpecification

schema:Thing > schema:Intangible > schema:PropertyValueSpecification

A Property value specification.
PropertyExpected TypeDescription
Properties from schema:PropertyValueSpecification
schema:defaultValue schema:Text  or
schema:Thing 
The default value of the input. For properties that expect a literal, the default is a literal value, for properties that expect an object, it's an ID reference to one of the current values.
schema:maxValue schema:Number The upper value of some characteristic or property.
schema:minValue schema:Number The lower value of some characteristic or property.
schema:multipleValues schema:Boolean Whether multiple values are allowed for the property. Default is false.
schema:readonlyValue schema:Boolean Whether or not a property is mutable. Default is false. Specifying this for a property that also has a value makes it act similar to a "hidden" input in an HTML form.
schema:stepValue schema:Number The stepValue attribute indicates the granularity that is expected (and required) of the value in a PropertyValueSpecification.
schema:valueMaxLength schema:Number Specifies the allowed range for number of characters in a literal value.
schema:valueMinLength schema:Number Specifies the minimum allowed range for number of characters in a literal value.
schema:valueName schema:Text Indicates the name of the PropertyValueSpecification to be used in URL templates and form encoding in a manner analogous to HTML's input@name.
schema:valuePattern schema:Text Specifies a regular expression for testing literal values according to the HTML spec.
schema:valueRequired schema:Boolean Whether the property must be filled in to complete the action. Default is false.
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:URL  or
schema:ImageObject 
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.
