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

urlschema:urlFormat '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).
