[Developers] Built With Freebase: Creative Commons Car Pictures

I fused data from dbpedia and freebase to construct a taxonomy of 
automobiles to build the following site:

http://carpictures.cc/

I've still got some work to do on the site,  but I'm already starting 
the o.e. work for a project that's going to be a hundred times larger.

One of the interesting things that came out of the project was that 
there were pretty big holes in both the freebase and dbpedia taxonomy of 
cars:  in particular,  there are a lot of cars in Freebase that don't 
have types on them.  (Freebase's car data seems to be strongest for 
recent cars that are covered in fueleconomy.gov.)   When it comes to 
older cars,   I had to use a crawl & filter strategy to expand the car 
categories to get a good list.  Once I get the last few false positives 
out,  I'd be interested in using the Freebase API to push the missing 
types into fbase.  I'm also interested in helping freebasers find the 
images that are in my system.

The big picture is to make something like the Flickr Wrapper that 
actually works.  I'd like to create a resolver where people can feed  
dbpedia,  freebase and other identifiers that point to named entities 
and get creative commons multimedia resources with very high precision.

Any feedback?
