What is PropertyValueSpecification?
A Property value specification.

This minimal example only identifies a Schema.org type. It is not a complete entity, a Google rich-result test, or a claim about a real business.

}Full parent hierarchy
Each chain starts at a root type. Multiple paths are shown when Schema.org defines more than one parent. For very complex types, up to 256 paths are displayed; consult the official definition for the full graph.

This list includes properties whose domainIncludes names PropertyValueSpecification or one of its ancestors. DomainIncludes is advisory; it is not an exhaustive set of permitted properties.
| Property | Expected value types | Description |
|---|---|---|
| additionalType | Text, 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. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org <a href="https://schema.org/docs/styleguide.html">style guide</a>. |
| alternateName | Text | An alias for the item. |
| defaultValue | Text, 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. |
| description | Text, TextObject | 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, Text, URL | The identifier property represents any kind of identifier for any kind of [[Thing]], such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See [background notes](/docs/datamodel.html#identifierBg) for more details. |
| image | ImageObject, URL | An image of the item. This can be a [[URL]] or a fully described [[ImageObject]]. |
| mainEntityOfPage | CreativeWork, URL | Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See [background notes](/docs/datamodel.html#mainEntityBackground) for details. |
| maxValue | Number | The upper value of some characteristic or property. |
| minValue | Number | The lower value of some characteristic or property. |
| multipleValues | Boolean | Whether multiple values are allowed for the property. Default is false. |
| name | Text | The name of the item. |
| owner | Organization, Person | A person or organization who owns this Thing. |
| potentialAction | Action | Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role. |
| readonlyValue | 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. |
| 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. |
| stepValue | Number | The stepValue attribute indicates the granularity that is expected (and required) of the value in a PropertyValueSpecification. |
| subjectOf | CreativeWork, Event | A CreativeWork or Event about this Thing. |
| url | URL | URL of the item. |
| valueMaxLength | Number | Specifies the allowed range for number of characters in a literal value. |
| valueMinLength | Number | Specifies the minimum allowed range for number of characters in a literal value. |
| valueName | 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. |
| valuePattern | Text | Specifies a regular expression for testing literal values according to the HTML spec. |
| valueRequired | Boolean | Whether the property must be filled in to complete the action. Default is false. |
