schema:PropertyValue

Definition

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.

Scope

Parent class(es): StructuredValue (https://schema.org/StructuredValue).

CDIF

Definition

Schema.org PropertyValue-based variableMeasured. Defines properties for a measured variable in a dataset, typed as schema:PropertyValue.

Scope

A measured variable described as a schema:PropertyValue. Lightweight discovery-level shape: name, description, optional measurement technique, optional value range (min/maxValue) and unit (unitCode/unitText). Richer per-variable structure is added by cdifDataDescription.

Attributes

Name	Type	Multiplicity	Description
identifier	XsdAnyUri	[0..1]	Documentation Original Reference schema:identifier Definition 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. Scope Domain: Thing (https://schema.org/Thing). Range: PropertyValue (https://schema.org/PropertyValue), Text (https://schema.org/Text), URL (https://schema.org/URL). CDIF Definition The primary identifier for the dataset; other identifiers should be listed in the sameAs field. Schema.org has three ways of encoding identifiers-- a text description, a URL, or by using the schema:PropertyValue field. The Science on Schema.org guidance strongly recommends using the PropertyValue approach. see https://github.com/ESIPFed/science-on-schema.org .... Dataset.md#identifier. Ideally, for any given data provided they would provide identifiers either all as strings or all as identifier_type. Scope @id - resolvable URI for the variable.
name	string	[0..1]	Documentation Original Reference schema:name Definition The name of the item. Scope Domain: Thing (https://schema.org/Thing). Range: Text (https://schema.org/Text). CDIF Definition string label associated with the variable in the dataset serialization Scope schema:name - label associated with the variable in the dataset.
description	string	[0..1]	Documentation Original Reference schema:description Definition A description of the item. Scope Domain: Thing (https://schema.org/Thing). Range: Text (https://schema.org/Text), TextObject (https://schema.org/TextObject). CDIF Definition A short summary describing a dataset. This text will be indexed by search applications, so the more information here, the better. Scope schema:description - free-text description of what the variable measures.
alternateName	string	[0..*]	Documentation Original Reference schema:alternateName Definition An alias for the item. Scope Domain: Thing (https://schema.org/Thing). Range: Text (https://schema.org/Text). CDIF Definition Alternate or abbreviated name(s) for this place. Scope schema:alternateName - additional human-readable name(s) for the variable.
minValue	string	[0..1]	Documentation Original Reference schema:minValue Definition The lower value of some characteristic or property. Scope Domain: MonetaryAmount (https://schema.org/MonetaryAmount), PropertyValue (https://schema.org/PropertyValue), PropertyValueSpecification (https://schema.org/PropertyValueSpecification), QuantitativeValue (https://schema.org/QuantitativeValue). Range: Number (https://schema.org/Number). CDIF Definition minimum numeric value in the dataset Scope schema:minValue - the lower bound of the values this variable can take (string for generality; concrete numeric type varies).
maxValue	string	[0..1]	Documentation Original Reference schema:maxValue Definition The upper value of some characteristic or property. Scope Domain: MonetaryAmount (https://schema.org/MonetaryAmount), PropertyValue (https://schema.org/PropertyValue), PropertyValueSpecification (https://schema.org/PropertyValueSpecification), QuantitativeValue (https://schema.org/QuantitativeValue). Range: Number (https://schema.org/Number). CDIF Definition maximum numeric value in the dataset Scope schema:maxValue - the upper bound of the values this variable can take.
unitCode	string	[0..1]	Documentation Original Reference schema:unitCode Definition 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. Scope Domain: PropertyValue (https://schema.org/PropertyValue), QuantitativeValue (https://schema.org/QuantitativeValue), TypeAndQuantityNode (https://schema.org/TypeAndQuantityNode), UnitPriceSpecification (https://schema.org/UnitPriceSpecification). Range: Text (https://schema.org/Text), URL (https://schema.org/URL). CDIF Definition URI or code identifying the unit of measure Scope schema:unitCode - URL/code identifying the unit of measure (e.g. UN/CEFACT Common Code, QUDT URI).
unitText	string	[0..1]	Documentation Original Reference schema:unitText Definition A string or text indicating the unit of measurement. Useful if you cannot provide a standard unit code for <a href='unitCode'>unitCode</a>. Scope Domain: PropertyValue (https://schema.org/PropertyValue), QuantitativeValue (https://schema.org/QuantitativeValue), TypeAndQuantityNode (https://schema.org/TypeAndQuantityNode), UnitPriceSpecification (https://schema.org/UnitPriceSpecification). Range: Text (https://schema.org/Text). CDIF Definition unit of measurement as text Scope schema:unitText - text label for the unit of measure (free form, complements unitCode).
