GENErAL DATA APPLICATIoNS
A growing number of general data-supplying applications are available.
Some applications provide large data files that you can download for free
or for a fee. Others are built with developers in mind with data accessible
via Application Programming Interface (API). This lets you use data from a
service, such as Twitter, and integrate the data with your own application.
Following are a few suggested resources:

a

Freebase ( www.freebase.com) —A community effort that mostly pro-

vides data on people, places, and things. It's like Wikipedia for data
but more structured. Download data dumps or use it as a backend
for your application.
Infochimps (

a

http://infochimps.org) —A data marketplace with free
and for-sale datasets. You can also access some datasets via
their API.
Numbrary (

a

http://numbrary.com) —Serves as a catalog for (mostly
government) data on the web.
AggData (

a

http://aggdata.com) —Another repository of for-sale data-
sets, mostly focused on comprehensive lists of retail locations.
Amazon Public Data Sets (

a

http://aws.amazon.com/publicdatasets) —
There's not a lot of growth here, but it does host some large scien-
tific datasets.
Wikipedia (

a

http://wikipedia.org) —A lot of smaller datasets in the
form of HTML tables on this community-run encyclopedia.

Outside more general data suppliers, there's no shortage of subject-
specific sites offering loads of free data.
