An open database of the world’s information. It’s built by the community and for the community – free for anyone to query, contribute to, build applications on top of, or integrate into their websites.
Drawing from large open data sets like Wikipedia, MusicBrainz, and the SEC archives, it contains structured information on many popular topics, including movies, music, people and locations – all reconciled and freely available via an open API.
By structuring the world’s data in this manner, the Freebase community is creating a global resource that will one day allow people and machines everywhere to access information far more easily and quickly than they can today.
the really powerful thing about this is that all these categories, these data types and the web of fields that define them, provide new hooks for applications that will be able to extract meaning from the data. That’s what makes Metaweb a kind of semantic web application.
Since Freebase is a much more structured information store than Wikipedia and is Creative Commons licensed, over time we may start seeing a lot of interesting mashups built on this service.
