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.
