To keep everyone in the loop:
There was a flurry of discussion on this proposal just now in IRC,
Some more use cases:
Books I've purchased (e.g. as done at AllConsuming)
(although Jim makes a good point that in that example the rating
is the interesting bit). Also:
Collectors (of stuff)
"Find me a friend, who has a copy of this book I want to read"

> Subject: [rdfweb-dev] Proposal: foaf:owns property
> We add a new property, foaf:owns, that can be used to indicate
> that an agent owns something. Initial use cases are to list
> a person's music and book collections.
> This property was recently proposed on this list  and
> briefly discussed  in the #foaf IRC channel.
> I recently proposed the addition of a new property to
> the FOAF namespace, foaf:owns, which would state that a
> given foaf:agent "owns" some other resource. Similarly to foaf:knows,
> the meaning of foaf:owns is deliberately general. I can therefore
> state that I own a house, dog, or book. E.g.:
> Other examples at:
> Which is a FOAF document that states that I own two albums.
> Inferences about what the ownership relationship will vary
> according to the type of foaf:Agent and the type of resource being
> There are many subtleties involved in modelling "ownership", complicated
> by jurisdictional boundaries, whether the item is a "spatial thing" or
> a "right". FOAF is not intended as a rights description language and
> therefore this kind of detailed modelling belongs in another vocabulary.
> However under the umbrella of creating "machine readable" homepages,
> in which people often list their music and book collections, whether
> they have any pets, etc., it seems worthwhile adding this general
> property to the FOAF namespace.
> Suggested Schema Changes
> Unless there are screams to the contrary, I suggest we add the following
> to the FOAF schema:
> <rdf:Property rdf:about="http://xmlns.com/foaf/0.1/owns"
> vs:term_status="unstable" rdfs:label="owns">
> <rdfs:domain rdf:resource="http://xmlns.com/foaf/0.1/Agent"/>
> <rdfs:range rdf:resource="http://www.w3.org/2000/01/rdf-schema#Resource"/>
> <rdfs:isDefinedBy rdf:resource="http://xmlns.com/foaf/0.1/"/>
