Global knowledge base built by a community of contributors, and open to everyone.

Freebase.com is home to a global knowledge base: a structured, searchable, writeable and editable database built by a community of contributors, and open to everyone. It could be described as a data commons. Freebase.com is enabled by the technology of Metaweb, which is described at www.metaweb.com.

Freebase is still in alpha with a limited number of users as we get things tidied up. With our Beta launch, Freebase will be open for general read with no registration required.

Freebase.com allows anyone to contribute, structure, search, copy and use data, through either the Freebase.com web site or through application program interfaces (APIs). Freebase makes it easy put data in and pull data out for any commercial or non-commercial purpose.

How is Freebase related to Metaweb?
Freebase was built by the team at Metaweb using technology they developed to allow extremely large volumes of data to be collected, organized, connected and modified by a community of contributors, developers, publishers, and people who just plain like data. It's also a great example of what's possible using Metaweb's technology.
