#ChiefRAhi tantek, please have a look at http://microformats.org/wiki/hproduct-issues on HP-9 and HP-10 problems. tobyink also provided his point of view on HP-9. Guys, please feel free to comment on them.
#ChiefRAtantek, I do please you to think about one more particular aspect for Real Estate: Google "imposed" the use of a new parameter called "availability".. which for homes doesn't fit. However, if you don;t use it, Google won't show you rich snippes based on that particular hProduct.
#ChiefRAyou can see it implemented also in the example I pasted you above.
#ChiefRAI had no other choice but to implement it with the parameter: in stock
#tantekby capturing documentation about the specifics of what Google supports, and how it extends hProduct, we can then better inform iterating on hProduct itself
#ChiefRAplease when you finish re-arranging hProduct part, place the proper links here with a short description so for me to know which is which. thanks.
