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

See

http://www.ebusiness-unibw.org/wiki/GoodRelations#Vocabularies_for_Products_and_Services_Types_and_Features

for a current list and

http://www.ebusiness-unibw.org/wiki/Own_GoodRelations_Vocabularies

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

http://www.heppnetz.de/ontologies/examples/toy

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.

Best wishes
