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

Constructors

SchemaPropertyValue.new({int? maxValue, dynamic measurementMethod, dynamic measurementTechnique, int? minValue, String? propertyID, String? unitCode, String? unitText, dynamic value, dynamic valueReference, String? additionalType, String? alternateName, dynamic description, String? disambiguatingDescription, dynamic identifier, dynamic image, dynamic mainEntityOfPage, String? name, SchemaAction? potentialAction, String? sameAs, dynamic subjectOf, String? url})
Create a new instance of SchemaPropertyValue

Properties

additionalType String?
//schema.org/docs/styleguide.html">style guide. Supported 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, String
getter/setter pair
image ↔ dynamic
An image of the item This can be a [URL] or a fully described [ImageObject]. Supported types: ImageObject, String
getter/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, String
getter/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, String
getter/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, String
getter/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, Event
getter/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, int
getter/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
