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:PropertyValue form of schema:identifier. Used when the codelist needs a structured identifier (propertyID + value + url) instead of a plain URI string.

JSON serialization: In a JSON instance, a property typed as Identifier may also be supplied as a plain string (the bare identifier value) or as an object reference ({"@id": ...}) instead of a full schema:PropertyValue object.

Attributes

Name	Type	Multiplicity	Description
propertyId	XsdAnyUri	[1]	Documentation Original Reference schema:propertyID Definition 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. Scope Domain: PropertyValue (https://schema.org/PropertyValue). Range: Text (https://schema.org/Text), URL (https://schema.org/URL). CDIF Definition schema:propertyID - URI of the identifier scheme (e.g. doi:, orcid:).
value	string	[1]	Documentation Original Reference schema:value Definition 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. Scope Domain: MonetaryAmount (https://schema.org/MonetaryAmount), PropertyValue (https://schema.org/PropertyValue), QuantitativeValue (https://schema.org/QuantitativeValue). Range: Boolean (https://schema.org/Boolean), Number (https://schema.org/Number), StructuredValue (https://schema.org/StructuredValue), Text (https://schema.org/Text). CDIF Definition schema:value - the identifier value within that scheme.
url	XsdAnyUri	[0..1]	Documentation Original Reference schema:url Definition URL of the item. Scope Domain: Thing (https://schema.org/Thing). Range: URL (https://schema.org/URL). CDIF Definition Web location of a page describing the codelist. Scope schema:url - resolvable URL form of the identifier.
