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.

Yes, it could. But actually I think there won't be a single namespace in which all model data will reside. Rather, there will be a mix of

- data from huge manufacturers, defined in their namespaces (http://www.sony.com/consumer/models/id/cellphone1234)
- data from third-party content providers (e.g. icecat.biz - note: the conversion is already being implemented by a group, so don't waste resources trying to do it)
- community platforms like product.db

And as said, some redundancy won't hurt and can be consolidated lateron easily. See for example the SPARQL CONSTRUCT rules at


CONSTRUCT {?u2 owl:sameAs ?u1.}
WHERE   {?u1 a gr:ProductOrServiceModel.
?u2 a gr:ProductOrServiceModel.
?u1 gr:hasEAN_UCC-13 ?ean1.
?u2 gr:hasEAN_UCC-13 ?ean2.
FILTER (?u1!=?u2 && ?ean1=?ean2 && ?ean1!="")}
