New FOAF Property : foaf:hasPersonalProfileDocument

While there exists a way, in FOAF, to say "There is a Personal Profile Document that has a primary topic of XXXX Person", there doesn't seem to be a way to say an inverse.

I wanted to say "Person XXXX has a Personal Profile Document at http://www.example.org/foaf/392j92j3".

There is a foaf:primaryTopic property, but there isn't an inverse. Also, it's domain is foaf:Document, which is too broad. I really want to link a foaf:Person to a foaf:PersonalProfileDocument.

So I've embedded the following RDF into all the Flickr FOAF:


<rdf:Property rdf:about="http://xmlns.com/foaf/0.1/hasPersonalProfileDocument">
<rdfs:domain rdf:resource="http://xmlns.com/foaf/0.1/Person" />
<rdfs:range rdf:resource="http://xmlns.com/foaf/0.1/PersonalProfileDocument" />
</rdf:Property>


Thoughts?
