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 provides an upper ontology for types of products and 
services, and their features. It is not an ontology for products and 
services. If you are looking for compatible ontologies for products and 
services, please check

a) eClassOWL. It defines >30,000 classes for products and >5,000 
properties of exactly the specificity you desire.
b) http://www.ebusiness-unibw.org/ontologies/consumerelectronics/v1
c) http://www.freeclass.eu/freeclass_v1



for a current list and


for background information.

The properties used in the primer / example are "toy" by purpose in 
order to explain the generic principle.

The primer states this clearly:

"In the following, we will use a toy ontology available at


for reasons of simplicity. That ontology defines four types of products, 
namely the classes. ..."

I can understand some annoyance by practitioners that early Semantic Web 
research did not live up to its bold statements. But frankly, I am the 
wrong audience for such complaints. I have been fighting for more than 
six years to develop practical solutions and applications of the 
Semantic Web vision in e-commerce.
