[Freebase-discuss] Querying Freebase for a relationship between nodes

[Spencer Kelly]

hey shahar, you've hit the nail on the head.
marriage in freebase is stored in a 'compound value type', so things
get a little more complicated.
its helpful maybe to think of this as a 1.5 ply connection
you can get the contents of a cvt by getting a topics incoming links,
then getting those outgoing links.
