General Info
Property value
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.\n\n Always use specific 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.

Declared Properties
PropertyType(s)Description and Constraints
schema:maxValuexsd:floatThe upper value of some characteristic or property.
schema:minValuexsd:floatThe lower value of some characteristic or property.
schema:propertyIDxsd:anyURI, xsd:stringA 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.
schema:unitCodexsd:anyURI, xsd:stringThe 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.
schema:unitTextxsd:stringA string or text indicating the unit of measurement. Useful if you cannot provide a standard unit code for unitCode.
schema:valueschema:StructuredValue, xsd:boolean, xsd:float, xsd:stringThe value of the quantitative value or property value node.\n\n* For [[QuantitativeValue]] and [[MonetaryAmount]], the recommended type for values is 'Number'.\n* For [[PropertyValue]], it can be 'Text;', 'Number', 'Boolean', or 'StructuredValue'.
schema:valueReferenceschema:Enumeration, schema:PropertyValue, schema:QualitativeValue, schema:QuantitativeValue, schema:StructuredValueA pointer to a secondary value that provides additional information on the original value, e.g. a reference temperature.
Inherited Properties
From schema:Thing:
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.
