Canonical URL: http://schema.org/additionalType

Thing > Property > rdf:type > additionalType

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. In RDFa syntax, it is better to use the native RDFa syntax - the 'typeof' attribute - for multiple types. Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.

Usage: Between 10,000 and 50,000 domains
