You have to clarify the usage of  http://schema.org/Boolean. The schema.org sponsors should clarify whether to use the RDF-compatible text (true/false) or the
URIs http://schema.org/True and http://schema.org/False.
For now, one would assume that you use the two values as individuals, e.g.
<link itemprop=”propertyname” href=”http://schema.org/True” />
<link itemprop=”propertyname” href=”http://schema.org/False” />
which is incompatible with the RDFa patterns and also less concise.
I suggest
<meta itemprop=”propertyname” content=”true” >
<meta itemprop=”propertyname” content=”false” >

Proposed change:

A simple text amendment for http://schema.org/True, http://schema.org/False, and http://schema.org/Boolean would do the trick.:

Note: The recommended use of this datatype is with a string “true” or “false” indicating the value of the respective property.
<div itemscope itemtype="http://schema.org/Book">
<span itemprop="name">The Catcher in the Rye</span>
 Family-friendly: <meta itemprop="isFamilyFriendly" content="true"> yes

Proposed action: Add this note to  http://schema.org/Boolean
