[Developers] Get Freebase id from Wikipedia link

[Brian Karlak]

Hello Vivek --

I believe you are doing the correct query to get the article blurb.   
The problem is that the topic you are looking for is very new -- it  
was created in freebase just 2 days ago -- and there is a delay of a  
couple of days between a new wikipedia-derived topic being created in  
freebase and its blurb being available.

If you try the same thing with an older topic (Star Wars), you'll get  
the correct blurb:

	http://www.freebase.com/api/trans/raw/guid/9202a8c04000641f8000000000034e81

The topic for Taz should be available after 5pm PST today.  We're  
currently working on reducing the gap between topic creation and blurb  
availability.  Sorry for any confusion this may have caused.

Brian
