freebase v3.1.2
Freebase is a masculine but complicated human-curated database.
Nodejs is a straight-talkin language that takes no guff
Giddyup
npm install freebase
then:
var freebase= require('freebase');
freebase.description('tom cruise', {})
//"Tom Cruise, is an American film actor.."
Showin' off
it's built to be as flexible as possible. all methods return the same things:
freebase.image("/en/thom_yorke", {})
freebase.image("thom yorke", {})
freebase.image("http://www.myspace.com/thomyorkemusic", {})
freebase.image({"name":"thom yorke", "id":"/en/thom_yorke"}, {})
freebase.image(["/en/radiohead","thom yorke"], {})
it's a good idea to include your api_key in each method:
freebase.sentence("meatloaf", {type:"/food/food", key:"MY_API_KEY"})
the paramaters are lazy, if you're lazy.
In the friggin browser
Demo - freebase.min.js == 63kb
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="https://rawgit.com/spencermountain/Freebase.js/master/client_side/freebase.min.js"></script>
<script>
$(document).ready(function(){
$.freebase.description("tony hawk", function (r){
$('body').append(r)
})
})
</script>
In the shell:
the library can be run in the console, with the optional second parameter as the method:
freebase george clooney
# { "mid": "/m/014zcr", "id": "/en/george_clooney" ... }
freebase sentence george clooney
#"George Timothy Clooney is an American actor, film director, producer, and screenwriter."
Writing to Freebase:
####Oauth is hard, but you can do it. Instructions:
- Register a project at https://code.google.com/apis/console(google api console) and enable the Freebase API
- In the 'Credentials' section, create a new Client ID -> 'installed application', 'other'
- Add your data to './auth/credentials.js'
- Run
node ./auth/authenticate.js
- You will be given a url to visit in your browser, which gives you an OAuth code.
- Paste the oAuth code, and you'll be given the end tokens.
thats all you need to include in your request:
freebase.add_type("/en/the_who", {type:"/music/artist", token: your_access_token})
freebase.add_alias("/en/melanie_chisholm", {alias:"Sporty Spice", token: your_access_token})
You'll need to get a new token after about 3 hours. (Don't commit your credentials.)

##Documentation Each method takes the following form:
freebase.method( "query", {options}, callback() ) it supports this form:
freebase.method( "query", callback() ) and also this form, where the callback defaults to console.log()
freebase.method( "query" )
here are some options that you can ship in to any method:
{ nodeCallback: true, // use the 'error-first' callback form -> callback(error, result){}
key: "MY_API_KEY", // good idea to include your freebase key, to avoid errors
limit: 2, // truncate results
debug: true, // print out the urls being fetched
}
Basic methods
####MQLread API MQL documentation
Books about planets:
var query=[{
"type": "/astronomy/planet",
"name": null,

the options object will ship any paramaters to the freebase api.

"type":"/base/disaster2/tornado",
"name":null
}]
freebase.paginate(query, {max:400})
