[Developers] how to determine a topic has been merged with another one?

[Augusto Callejas]

hi-

there is a guid that looks like it was merged with another one.
i query the guid for type information, and get nothing back:

query/response:
===
{
  "guid" : "#9202a8c04000641f8000000000544767",
  "type" : []
}
---
{
  "guid" : "#9202a8c04000641f8000000000544767",
  "type" : []
}
===

when i visit that guid through the url:

 http://www.freebase.com/view/guid/9202a8c04000641f8000000000544767

it redirects to a new page:

 http://www.freebase.com/view/authority/imdb/name/nm1939267

i determined the new guid is:

query/response:
===
{
  "guid" : null,
  "name" : "T.I.",
  "type" : "/people/person"
}
---
{
  "guid" : "#9202a8c04000641f8000000006d3caa0",
  "name" : "T.I.",
  "type" : "/people/person"
}
===

so my question is how do i determine via mql that guid
9202a8c04000641f8000000000544767 was merged to guid
9202a8c04000641f8000000006d3caa0?  i know that the website knows how to
perform the redirect to the new guid, but how do i know via mql the new guid
i should be looking at?

thanks,
augusto.
