Clients consuming schema.org markup in RDF environments should translate the additionalType property to rdf:type, at least if the value of this property is a valid URI that identifies a class (e.g. if it comes from the http://www.productontology.org/id/* namespace).

> Dear all:
> I am happy to announce that the sponsors of schema.org, i.e. Google, Yahoo, Bing, and Yandex, have just implemented my proposal (from September 2011) to add a new property additionalType to http://schema.org/Thing and thus also to http://schema.org/Product.
> This allows using the more than 300,000 precise product type identifiers from our http://www.productontology.org service for telling search engines very, very precise the type of products or services you are selling.
> For example, a racing bike should now be marked up as follows:
> <div itemscope itemtype="http://schema.org/Product">
>    <link itemprop="additionalType" href="http://www.productontology.org/id/Racing_bicycle" />
>    <!-- other schema.org properties go in here -->
> </div>	
> You can use any reasonable Wikipedia entry for that.
> See 
>    http://www.productontology.org/doc/Racing_bicycle#microdata
> for more details.
> This is also the first step in the ongoing effort to make the GoodRelations vocabulary fully available from the schema.org namespace.
> Best wishes
> Martin
