[Developers] [Data-modeling] is everyone married to themselves?

[John Giannandrea]

spouse is symmetric, so its hard to eliminate the thing that you are  
constraining by without a forward reference.
this gets you close, but it wont deal with Hillary if she wins:

   "query" : [
     {
       "p:spouse" : [
         {
           "name" : null,
           "type" : "/government/us_president"
         }
       ],
       "spouse" : [
         {
           "education" : [
             {
               "institution" : null
             }
           ],
           "name" : null,
           "type" : {
             "id" : "/government/us_president",
             "optional" : "forbidden"
           }
         }
       ],
       "type" : "/people/marriage"
     }
   ]
