Freebase.com has an open API that can be used to access and update structured data. The API is completely documented at Freebase.com along with some simple examples of how to program for the API.

This project has two complete and usable Python client APIs.

• metaweb-py: This is a single-file interface based on the "metaweb.py" originally developed by David Flanagan and reproduced in our online documentation. This version has some updates and improvements over the original.

• freebase-api: This is a more ambitious and complete implementation originally developed by Nick Thompson for a number of projects we've been working on in-house.

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