I'm not sure what the problem is, but does this answer your question?

"The foaf:isPrimaryTopicOf property is inverse functional: for any  
document that is the value of this property, there is at most one thing in  
the world that is the primary topic of that document. This is useful, as  
it allows for data merging, as described in the documentation for its  
inverse, foaf:primaryTopic.: "
