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] Excellent News: Yahoo Provides Tool for GoodRelations for Website Owners

Dear all:

Great news for GoodRelations:

As of now, Yahoo will display price and offering details and other 
meta-data of any e-commerce Web page if the site owner uses the free 
GoodRelations vocabulary.

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 his offers in Yahoo.

Just go to


and click on the tab "RDFa - GoodRelation".

The tool generates mark-up patterns for you to insert into your page.

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.

PS: We will shortly publish an step-by-step recipe in the GoodRelations 
Wiki at


Stay tuned!

Best wishes
