Property	Expected Type	Description
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: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.
