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
