Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.

image	URL  or ImageObject	URL of an image of the item.
name	Text	The name of the item.
potentialAction	Action	Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
sameAs	URL	URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Freebase page, or official website.
