[Developers] retrieving a type's description

[Augusto Callejas]

hi-

how can i retrieve the type description of a type?
for instance, on:

  http://freebase.com/view/filter?id=/location/location

i'd like to retrieve:

 The Location type is used for any topic with a fixed location.  It includes
 geographic features such as oceans and mountains, political enties like
 cities and man-made objects like buildings.

i don't see a property in "/type/type".

thanks,
augusto.
