Dear all: http://www.productontology.org, a service that produces more than 300,000 precise class definitions for types of products and services, is now fully schema.org-compatible and can be used to add precision to the generic http://schema.org/Product class. Examples: http://www.productontology.org/doc/Racing_bicycle http://www.productontology.org/doc/Racing_bicycle#microdata http://www.productontology.org/doc/Pancake http://www.productontology.org/doc/Pancake#microdata http://www.productontology.org/doc/Vinegar http://www.productontology.org/doc/Vinegar#microdata http://www.productontology.org/doc/Retention_basin http://www.productontology.org/doc/Retention_basin#microdata For each definition, Turtle, RDF/XML, and HTML is available: http://www.productontology.org/doc/Racing_bicycle.ttl http://www.productontology.org/doc/Racing_bicycle.rdf http://www.productontology.org/doc/Racing_bicycle.html Note that we do not use the flawed schema.org extension mechanism, but instead recommend the RDF-style way of narrowing down the meaning by adding a second class membership: <div itemscope itemtype="http://schema.org/Product"> <a itemprop="http://www.w3.org/1999/02/22-rdf-syntax-ns#type" href="http://www.productontology.org/id/Retention_basin"></a> <!-- other schema.org properties go in here --> </div> Instead of the empty <a> element, you could also use <link> if the WHATWG eventually decides to accept <meta> and <link> in the document body, which would be a good thing.
