SchemaPropertyValue class
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 schema.org 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. See https://schema.org/PropertyValue

types: String, String
getter/setter pair
- alternateName ↔ String?
-
An alias for the item.
getter/setter pair
- description ↔ dynamic
-
A description of the item. Supported types: String,
TextObject
getter/setter pair - disambiguatingDescription ↔ String?
-
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.
getter/setter pair
- hashCode → int
-
The hash code for this object.
no setterinherited
- identifier ↔ dynamic
-
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 for more details Supported types:PropertyValue
, String, Stringgetter/setter pair - image ↔ dynamic
-
An image of the item This can be a [
URL
] or a fully described [ImageObject
]. Supported types:ImageObject
, Stringgetter/setter pair - mainEntityOfPage ↔ dynamic
-
Indicates a page (or other CreativeWork) for which this thing is
the main entity being described See background
notes for details.
Supported types:
CreativeWork
, Stringgetter/setter pair - maxValue ↔ int?
-
The upper value of some characteristic or property.
getter/setter pair
- measurementMethod ↔ dynamic
-
A subproperty of [measurementTechnique] that can be used for
specifying specific methods, in particular via
[
MeasurementMethodEnum
]. Supported types:DefinedTerm
,MeasurementMethodEnum
, String, Stringgetter/setter pair - measurementTechnique ↔ dynamic
-
"mass spectrometry" or "nmr spectroscopy" or "colorimetry" or
"immunofluorescence" If the [
variableMeasured
] is "depression rating", the [measurementTechnique] could be "Zung Scale" or "HAM-D" or "Beck Depression Inventory" If there are several [variableMeasured
] properties recorded for some given data object, use a [PropertyValue
] for each [variableMeasured
] and attach the corresponding [measurementTechnique] The value can also be from an enumeration, organized as a [MeasurementMetholdEnumeration
]. Supported types:DefinedTerm
,MeasurementMethodEnum
, String, Stringgetter/setter pair - minValue ↔ int?
-
The lower value of some characteristic or property.
getter/setter pair
- name ↔ String?
-
The name of the item.
getter/setter pair
- potentialAction ↔ SchemaAction?
-
Indicates a potential Action, which describes an idealized
action in which this thing would play an 'object' role.
getter/setter pair
- propertyID ↔ String?
-
A 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. Supported types: String, String
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- sameAs ↔ String?
-
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.
getter/setter pair
- subjectOf ↔ dynamic
-
A CreativeWork or Event about this Thing. Supported types:
CreativeWork
, Eventgetter/setter pair - unitCode ↔ String?
-
The 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. Supported types:
String, String
getter/setter pair
- unitText ↔ String?
-
A string or text indicating the unit of measurement Useful if
you cannot provide a standard unit code for unitCode.
getter/setter pair
- url ↔ String?
-
URL of the item.
getter/setter pair
- value ↔ dynamic
-
The value of a [
QuantitativeValue
] (including [Observation
]) 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'.\n* Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols.\n* Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point Avoid using these symbols as a readability separator. Supported types: String,StructuredValue
, bool, intgetter/setter pair - valueReference ↔ dynamic
-
A secondary value that provides additional information on the
original value, e.g a reference temperature or a type of
measurement. Supported types:
DefinedTerm
,Enumeration
,MeasurementTypeEnumeration
,PropertyValue
,QualitativeValue
,QuantitativeValue
, String,StructuredValue
getter/setter pair
