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 François-Paul:

The modeling proposed turns your ontology into OWL Full, since 


is a subproperty of owl:ObjectProperty while


is a subproperty of owl:DatatypeProperty, and in OWL DL, no property can be both.

If you need to model the case that people should use RDF literals (text, number, whatsoever) and URIs of enumerated values, you could define a subproperty of 


and set the range to rdfs:Literal.

This would allow all typed and untyped RDF Literals, which includes xsd:anyURI for URIs.

A similar pattern can also be used when the values of URIs include classes and individuals and you don't want to break OWL DL.
