"Open database of the worldâ€™s information. Itâ€™s built by the community and for the community â€“ free for anyone to query, contribute to, build applications on top of, or integrate into their websites.
"Already, Freebase covers millions of topics in hundreds of categories. 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 â€“ all reconciled and freely available via an open API. This information is supplemented by the efforts of a passionate global community of users who are working together to add structured information on everything from philosophy to European railway stations to the chemical properties of common food ingredients.
"By structuring the worldâ€™s data, 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."
"DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia, and to link other data sets on the Web to Wikipedia data."
