Hi Soheila,
in general, it is possible to import Goodrelations and create 
specializations of existing conceptual elements. for example, you can 
create additional instances of gr:PaymentMethod or gr:DeliveryMode classes.

However, it is usually much better to specify concrete feature requests 
using the mailing list goodrelations at ebusiness-unibw.org, because any 
specializations of GoodRelations elements may have weaker application 
support. For example, if you create an individual representing a 
national mail delivery service instead of gr:DeliveryModeMail, such may 
be more specific, but will on the other hand reduce application support 
and the recall of other users' queries, because your extensions will not 
be as widely known as the core vocabulary.

Also, note that extending an ontology in a consistent way requires a 
deep understanding of the underlying conceptual choices and of 
conceptual modeling in general.

So in a nutshell, I would discourage such extensions.

An exeception is the creation of domain-specific vocabularies for the 
*types* and *properties* of products or services. A recipe for that is 
given at
