Multiple Types in Schema.org
This is a trivial-example showing the wiki markup structure for including pretty-printed HTML markup in a Wiki page:
<div itemscope="" itemtype="http://schema.org/SoftwareApplication http://schema.org/MobileApplication">
<p itemprop="operatingSystems">OSX 10.6</p>,
<p itemprop="operatingSystems">Windows 7</p>
It also (to stay on topic) shows a Microdata syntax for mentioning multiple types. In this case it is quite a redundant example, since every MobileApplication is already known to be a SoftwareApplication too.
- for types in another vocabulary, the http://schema.org/additionalType property can be used in Microdata. In RDFa, the @typeof attribute can use multiple schemas directly.
- the schema.org design has built-in multiple types for everything below LocalBusiness, since every LocalBusiness is both an Organization and a Place
- A common candidate for multiple-typing is Product, since many other type hierarchies are things that also serve as Products
