GoodRelations is a standardized vocabulary for product, price, and company data that can (1) be embedded into existing static and dynamic Web pages and that (2) can be processed by other computers. This increases the visibility of your products and services in the latest generation of search engines, recommender systems, and other novel applications.

Dear all:
I have often been asked in which countries Google Rich Snippets will show when you are using GoodRelations in RDFa syntax in your site.
As of today, I can confirm this for
google.com
google.de
google.co.uk
google.ru
So you can see that the number of countries with GoodRelations support is already much bigger than what Google officially communicates.
Google does not seem to show rich snippets for other countries yet.
There are a few things to note in here:
1. The fact that Google is not yet showing rich snippets in your country does not mean that respective markup is ignored, because
a) it also sends relevance signals to Google and
b) it may already been cached so that rich snippets can be shown immediately once a new country is added to the list. If you add rich markup only at the moment support for your country is officially announced, it may take 8 - 10 weeks for your site to be reindexed completely.
2. Depending on your site relevance and the quality of your sitemap.xml, it will take anything between a few weeks and several months for rich snippets to show for your page. So don't be frustrated if you add the markup and nothing happens for a few weeks. Just be patient! If the Google validator [1] confirms the markup, you are all set.
3. Google uses a component to judge whether a snippet should be shown for your page or not. While they do not reveal details on this component, the general experience is that highly ranked / highly reputable sites will show rich snippets more often than rather unknown or low-ranked sites.
Attached, find a few screenshots that show rich snippets based on GoodRelations for the query
"Rachael Ray Enamel on Steel 16.75x13.25-in. Roaster with Rack: Orange"
in various countries. I also attach one example of a country without support at this moment (Spain).
Best wishes
