GoodRelations - The Web Vocabulary for E-Commerce

This is the archive of the goodrelations dicussion list

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.

[goodrelations] Breaking News: GoodRelations data now shows up in Yahoo!

Dear all:

I can report on the first confirmed page with GoodRelations + RDFa rich 
meta-data that shows up in Yahoo with additional details:

URI: http://tr.im/yahooproduct2

Screenshot attached. The price of $ 34.99 comes directly from the RDFa 
markup, as described in the recipe at


Thanks to Peter Mika, Evan Goer, and Kevin Haas for their hard work in 
fine-tuning the parsing & processing. Theoretically, there should also 
be the product image next to the search result; we are currently working 
on fixing that, too.

But the good news is: There is now a crystal-clear, easy-to-communicate 
incentive for any webmaster in the world to add price and product 
descriptions using GoodRelations in RDFa to all pages.

Please spread the word!
