Re: Excellent News for LOD: Yahoo Provides Tool for RDFa+GoodRelations for Site Owners

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.

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.

Martin
