What are the rules for using data in Freebase?
The rules for using Freebase data depend on the type of content it is. Data is available for use under the Creative Commons Attribution Only (or CC-BY) license. This means you are free to use it on your site, as long as you credit the Freebase community appropriately. The Freebase attribution policy on the Wiki has all the details.
Many of the images in Freebase are also CC-BY, although some images are hosted under different license terms, such as the GFDL (which is similar to CC-BY), public domain, or Fair Use, and you can use the Freebase API to filter your results by license type. Finally, long descriptions that they have pulled in from Wikipedia are licensed under the GFDL.
Can I use Freebase data for my business?
Yes, you are allowed under the terms of Freebase's Creative Commons Attribution (CC-BY) license, as long as you attribute Freebase as the source of your data. See the Freebase Terms of Service for more details.
API use is limited to 100,000 requests per day. If you need more, you have two options:
- Use the downloadable Data Dumps to work with Freebase data offline. This option is best for higher volume use.
- Increase your quota using the instructions at Requesting additional quota. This option is best for lower volume use above the initial 100,000 requests
