I think a simple solution is to widen the definition of a product to "any object or happening on which rights can be transferred" - this is exactly as GoodRelations understands products.


The advantage is that you can use the very same conceptual structures for various industries.

Also see http://www.productontology.org/#faq5 :

"The semantics of gr:ProductOrService is basically that of a tangible or intangible object on which rights can granted or transferred, so even if social conventions tell us that rain, love, health, longevity, or sex should not be traded, they are not necessarily invalid as subclasses of gr:ProductOrService, because in some environments, it may be perfectly valid to sell rain or seek health by means of RDF and GoodRelations."

However, it would be nice to markup the same "object" with both types (Residence as a Product, "residence for sale"). As such you take advantage of the Residence properties which I believe you like. Unfortunately by now this is not possible due to microdata restrictions (see itemscope/itemtype at http://www.w3.org/TR/html5/microdata.html  and the discussion at http://www.jenitennison.com/blog/node/161 ).
