Property value specification
A Property value specification.
Class Axioms
Declared Properties
PropertyType(s)Description and Constraints
schema:defaultValueschema:Thing, xsd:stringThe 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:maxValuexsd:floatThe upper value of some characteristic or property.
schema:minValuexsd:floatThe lower value of some characteristic or property.
schema:multipleValuesxsd:booleanWhether multiple values are allowed for the property. Default is false.
schema:readonlyValuexsd:booleanWhether 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:stepValuexsd:floatThe stepValue attribute indicates the granularity that is expected (and required) of the value in a PropertyValueSpecification.
schema:valueMaxLengthxsd:floatSpecifies the allowed range for number of characters in a literal value.
schema:valueMinLengthxsd:floatSpecifies the minimum allowed range for number of characters in a literal value.
schema:valueNamexsd:stringIndicates the name of the PropertyValueSpecification to be used in URL templates and form encoding in a manner analogous to HTML's input@name.
schema:valuePatternxsd:stringSpecifies a regular expression for testing literal values according to the HTML spec.
schema:valueRequiredxsd:booleanWhether the property must be filled in to complete the action. Default is false.

PropertyType(s)Description and Constraints
schema:additionalTypexsd:anyURIAn 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. tools may have only weaker understanding of extra types, in particular those defined externally.
schema:alternateNamexsd:stringAn alias for the item.
schema:descriptionxsd:stringA description of the item.
schema:disambiguatingDescriptionxsd:stringA 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.
schema:imageschema:ImageObject, xsd:anyURIAn image of the item. This can be a [[URL]] or a fully described [[ImageObject]].
schema:mainEntityOfPageschema:CreativeWork, xsd:anyURIIndicates a page (or other CreativeWork) for which this thing is the main entity being described. See [background notes](/docs/datamodel.html#mainEntityBackground) for details.
schema:namexsd:stringThe name of the item.
schema:potentialActionschema:ActionIndicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
schema:sameAsxsd:anyURIURL 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:urlxsd:anyURIURL of the item.
