Freebase.com has an open API that can be used to access and update structured data. The RESTful http-based API is completely documented at Freebase.com along with some simple examples. This library provides a python interface to that API.

Usage should be as simple as:

>>> import freebase
>>> freebase.mqlread({"id": "/en/david_bowie", "name": None})
{u'id': u'/en/david_bowie', u'name': u'David Bowie'}

Discussion of this project is hosted at Freebase developers mailing list.
