Wikipedia defines Linked Data as a term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF.Linked Data is about using the Web to connect related data that wasn't previously linked, or using the Web to lower the barriers to linking data currently linked using other methods. The over 200 semantic web datasets currently contains over 25 billion triples of linked data and 400 million RDF links.http://linkeddata.org/14Killer apps with public data - a cloud of opportunity?Graphic by semanticwebcompany@ Flickr, CC BY-NC-SA
DBpedia isa community effort toextract structured information from Wikipedia andtomake this information available onthe Web. DBpedia allows youtoask sophisticated queries against Wikipedia, andtolink other data sets onthe WebtoWikipedia data. TheDBpedia knowledge base currently describes more than 2.6 million things, including atleast 213,000 persons, 328,000 places, 57,000 music albums, 36,000 films, 20,000 companies.
