Freebase is a very masculine but complicated human-curated database.

Nodejs is a straight-talkin language that takes no guff

Usage

    var freebase=require('node-freebase');
    freebase.description('tom cruise', [options], [callback])
    //"Tom Cruise, is an American film actor.."

Showin' off

it's built to be as flexible as possible. all methods can handle the same things:

    freebase.sentence("/en/thom_yorke")//freebase link
    freebase.weblinks("thom yorke")//search term
    freebase.wikipedia_categories("http://www.myspace.com/thomyorkemusic")//weblink
    freebase.search({"name":"thom yorke", "id":"/en/thom_yorke"})//freebase object
    freebase.notable(["/en/radiohead","thom yorke"])//array of stuff

this properly handles many asynchronous requests, rate-limiting them to 10-at-a-time.

    freebase.images(["johny greenwood", "thom yorke", "marvin gaye"], {max:10}, console.log)

this is pretty clever i'd say:

    freebase.sentence("meatloaf", {type:"/food/food"}, console.log)

and when you're hacking in the console:

$ freebase sentence "thom yorke"
