Re: Generic Property-Value Proposal for Schema.org

Following your suggestion, I have just changed the range of value to include StructuredValue instead of PropertyValue (anf fixed this for valueReference, too).

This allows using the mechanism in such cases when the property does not have a URI but the value has one (e.g. im DBPedia), or when you want the value to be an entity for linking to it lateron. 

Examples:

<div itemtype="http://schema.org/Product">
  <span itemprop="name">Digital Camera 123</span>
  <div itemprop="additionalProperty" itemscope itemtype="http://schema.org/PropertyValue">
	  <span itemprop="name">Interface</span>:
  	  <div itemprop="value" itemscope itemtype="http://schema.org/QualitativeValue">
	  	<span itemprop="name">RS232</span
		<link itemprop="sameAs" href="http://dbpedia.org/resource/RS232" />
       </div>   
  </div>  
</div>


<div itemtype="http://schema.org/Product">
  <span itemprop="name">Digital Camera 123</span>
  <div itemprop="additionalProperty" itemscope itemtype="http://schema.org/PropertyValue">
	  <span itemprop="name">Interface</span>:
  	  <link itemprop="value" href="http://dbpedia.org/resource/RS232" />
       </div>   
  </div>  
</div>

The Wiki page and the Mercurial repository are already up-to-date.

My only concern is the following: it must allow to use a URI for the object of the property (the "feature") when we have one, (and minting one should be encouraged otherwise), because this allows to publish data as they are, and to lift them later.
