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.

Dear all:

The amount of real-world GoodRelations data is growing substantially! Here is a shortlist of major examples. 

1. BestBuy stores (ca. 1000)

Simply fetch all URIs listed in


2. BestBuy offers (430,000)

Simply fetch all URIs listed in


3. O'Reilly Offers

O'Reilly has started to add GoodRelations in RDFa to their production Web site, see e.g. 


Their sitemap is t


As far as we know, only pages of the pattern


do contain relevant RDFa.

4. SaveOnVideo.com (8,000 products) 
SaveOnVideo.com exposes its full catalog of 8,000 items using GoodRelations in RDFa.

Fetch all pages from


5. There is model data about the 500 most relevant camcorders at


6. http://productdb.org/ exposes product descriptions and reviews from 
ProductWiki using a blend of GoodRelations, FOAF and OpenVocab. There 
is also a SPARQL endpoint at 


I don't know of a sitemap, but you can query the endpoint at


for all gr:ProductOrServiceModels

   SELECT ?m WHERE {m a 

and then retrieve them as RDF/XML files by adding ".rdf" to the URIs 
from the result set:

   <binding name="m"

--> fetch


7. http://www.universum-shop.de has added GoodRelations + RDFa to all individual items


Unfortunately, there is no sitemap.xml

8. OpenEAN: There is an RDF/XML transcript of 1 Mio product models 
and their EAN/UPC code at http://openean.kaufkauf.net/id/

The semantic (!) sitemap (mind the differing element names) is at


9. The oxid eSales Shop: http://www.waffen-frank-shop.de/ has GoodRelations markup in all item pages.

There is an RDF/XML dump at


The content in the dump is identical to the RDFa markup in all individual pages, e.g.



10. Magento Shop: http://www.la-mousson.de/ has GoodRelations markup in all item pages.




and extract the RDFa markup from all pages.

Most of those should be recrawled every 24 hours.

This is just a shortlist, and I am currently in contact with many major online retailers on adding GoodRelations to their sites.

Best wishes
