Class Property
2 typesschema.org
An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org [style guide](https://schema.org/docs/styleguide.html).
Class Property
1 typeschema.org
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.
Class Property
3 typesschema.org
The identifier property represents any kind of identifier for any kind of [Thing](https://schema.org/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](https://schema.org/docs/datamodel.html#identifierBg) for more details.
Class Property
1 typeschema.org
This can be marked 'true' to indicate that some published [DeliveryTimeSettings](https://schema.org/DeliveryTimeSettings) or [ShippingRateSettings](https://schema.org/ShippingRateSettings) are intended to apply to all [OfferShippingDetails](https://schema.org/OfferShippingDetails) published by the same merchant, when referenced by a [shippingSettingsLink](https://schema.org/shippingSettingsLink) in those settings. It is not meaningful to use a 'true' value for this property alongside a transitTimeLabel (for [DeliveryTimeSettings](https://schema.org/DeliveryTimeSettings)) or shippingLabel (for [ShippingRateSettings](https://schema.org/ShippingRateSettings)), since this property is for use with unlabelled settings.

Class Property
1 typeschema.org
Label to match an [OfferShippingDetails](https://schema.org/OfferShippingDetails) with a [DeliveryTimeSettings](https://schema.org/DeliveryTimeSettings) (within the context of a [shippingSettingsLink](https://schema.org/shippingSettingsLink) cross-reference).
