Re: How to find a proper ontology for my classes and properties?

Hi Juri,

Just in case you are actually searching for a property for ownership  
in the legal sense: Please use

    http://purl.org/goodrelations/v1#owns

This property indicates that a particular person or business owns a  
particular product. It can be used to expose the products in one's  
posession in order to empower recommender systems to suggest matching  
offers.

Best
Martin
