Hi Seth:
Well at first blush this is good news. But then why do we want to use a vocabulary like product:listPrice which is locked to a specific yahoo domain: http://search.yahoo.com/searchmonkey/product/ ? Is Google going to come along with another different word for that? Then which one does a catalog owner choose?
Note that the Yahoo "product" vocabulary is a legacy from earlier vocabularies. You can use pure GoodRelations for 99% iof the current usages of that vocabulary and it will be equally honored by SearchMonkey, afaik. Make sure you click on the "RDFa + GoodRelations" tab at
http://developer.search.yahoo.com/help/objects/product So you can also use <div rel="gr:offers"> <div typeof="gr:Offering"> <!-- Two price specifications: a list price and a sale price --> <div rel="gr:hasPriceSpecification"> <span property="gr:hasCurrencyValue">34.99</span> <span property="gr:hasCurrency">USD</span> </div> etc. I will publish a more complete example at http://www.ebusiness-unibw.org/wiki/GoodRelations_Examples shortly.
Is Google going to come along with another different word for that? Then which one does a catalog owner choose?
I am currently in contact with Google and trying to communicate the advantages of using standard vocabularies for meta-data, and I think there are strong arguments.
Also note that it is fairly easy to transform any Google-specific mark-up into standardized GoodRelations mark-up, and that several related tools are in the making.

Previously, such data was only used within special applications developed in the Yahoo ecosystem. Now, every site owner can add meta-data to enhance the search results of offers in Yahoo. Just go to http://developer.search.yahoo.com/help/objects/product and click on the tab "RDFa - GoodRelation". The tool generates mark-up patterns for copy-and paste into xhtml page content. Thanks to Peter Mika and everybody at Yahoo for this initiative! It will for sure help lower the entrance barrier for any business to use Semantic Web technology in general and GoodRelations in particular.
