Syntax for boolean in schema.org?

Dear Dan:

I think the following issue is still open:

	http://lists.w3.org/Archives/Public/public-vocabs/2012Apr/0038.html
	http://www.w3.org/2011/webschema/track/issues/14

Is there, in the meantime, consensus on whether boolean values should 
use

- the URI of http://schema.org/True and http://schema.org/False
	<link itemprop="property_name" href="http://schema.org/True />

- the lower-caps literal values "true" and "false" or
	<meta itemprop="property_name content="true">

- the same literals with an initial capital letter, i.e. "True" and "False"?
	<meta itemprop="property_name content="True">

Even if the Google parsers are tolerant with this, I think developers would love to have a definite specification.

A simple solution would be to implement the proposal dated April 2012, i.e.

1. 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.
Example:
<div itemscope itemtype="
http://schema.org/Book
">
<span itemprop="name">The Catcher in the Rye</span>
 Family-friendly: <meta itemprop="isFamilyFriendly" content="true"> yes
</div>

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

Thanks!

Martin
