Mashups, APIs andlinked open data– They do not work with clients that have not beendesigned with the specificAPI in mind.– Their content cannot be accessed by search enginesand other generic web agents.– Each mashup only allows access to data froma limited number of sources chosen by the developer.In contrast, information on the Semantic Web canbe used by generic clients, including RDF browsers,RDF search engines, and web query agents.The RDF Book Mashup: From Web APIs to a Web of DataChristian Bizer, Richard Cyganiak, and Tobias Gauß
