Property Value

A property-value pair.

Always use specific properties when they exist and you can populate them. Using PropertyValue as a substitute will typically not convey as much semantic information as using the specific property. Most of the time a PropertyValue node will need a value property (e.g. most of the examples on https://schema.org/PropertyValue have one) so this schema make that property required. This type is mainly provided for use in Thing.identifiers (see the notes there).

Properties

Name	@id	Type	Description	Inherited from
value	schema:value	boolean or integer or number or string	The value of the property. See note 1.	PropertyValue
alternateNames	schema:alternateName	Array of string	Alternate names (aliases) for the item.	Thing
description	schema:description	Array of BlockContent or Array of InlineContent or string	A description of the item. See note 2.	Thing
id	schema:id	string	The identifier for this item.	Entity
identifiers	schema:identifier	Array of (PropertyValue or string)	Any kind of identifier for any kind of Thing. See note 3.	Thing
images	schema:image	Array of (ImageObject or Format 'uri')	Images of the item.	Thing
meta	stencila:meta	object	Metadata associated with this item.	Entity
name	schema:name	string	The name of the item.	Thing
propertyID	schema:propertyID	string	A commonly used identifier for the characteristic represented by the property.	PropertyValue
url	schema:url	Format 'uri'	The URL of the item.	Thing

Notes

1. value : This follows the expected types of https://schema.org/value except for StructuredValue, which at the time of writing was not implemented in this schema.
2. description : Allows for the description to be an array of nodes (e.g. an array of inline content, or a couple of paragraphs), or a string. The minItems restriction avoids a string being coerced into an array with a single string item.
3. identifiers : Some identifiers have specific properties e.g the issn property for the Periodical type. These should be used in preference to this property which is intended for identifiers that do not yet have a specific property. Identifiers can be represented as strings, but using a PropertyValue will usually be better because it allows for propertyID (i.e. the type of identifier).
