On this page, we summarize examples of GoodRelations RDFa markup that goes beyond the basic Google and Yahoo recipes but should be accepted by parsers and validation tools.

As of 2011-04-26, there are only minor problems: Yahoo and Google use differing formats for reviews and image information, and if a gr:Offering is linked with a gr:BusinessEntity via gr:seeks, it should not be displayed in search results, because it represents demand, not supply. However, this is only a small problem, since the amount of such data is very small on a Web scale, and RDFa syntax is not likely to be the main format for such demand data. The original Yahoo recipe from 2008 does not validate with Google's tool, but the other testcases show that it is possible to create mark-up that validates with both Yahoo and Google, and that adding richer GoodRelations patterns, e.g. by using the VSO or TIO extensions for cars or tickets, does not conflict with being Google- and Yahoo-compatible.
