[Developers] Counting mediated links

[Benjamin Goldenberg]

I'm working on a project to analyze Freebase as a social network. To  
do so, I would like to count the number of links between /people/ 
person topics, which I can do easily with the following query:

{
   "return" : "count",
   "source" : {
     "id" : "/en/bob_dylan"
   },
   "target" : {
     "type" : "/people/person"
   },
   "type" : "/type/link"
}

But this doesn't count links through CVTs, such as marriages. Is it  
possible to construct such a query? I've been playing with queries  
like the one below, but haven't been successful.

{
   "return" : "count",
   "source" : {
     "id" : "/en/bob_dylan"
   },
   "target" : {
     "/type/reflect/any_master" : {
       "type" : "/people/person"
     },
     "type" : {
       "/freebase/type_hints/mediator" : true
     }
   },
   "type" : "/type/link"
}
