Hi, a central strength of the Semantic Web is that it allows you to set links between information about the same object within multiple data sources. Our RDF book mashup [1] generates RDF descriptions about books and their authors. A second publicly available bibliographic data source is the DBLP database containing journal articles and conference papers. The DBLP database is published as linked data by a D2R Server at http://www4.wiwiss.fu-berlin.de/dblp/. In order to demonstrate links between different data sources, we have added another feature to the RDF book mashup: The mashup now automatically generates owl:sameAs links between book authors and paper authors in the DBLP database. Using Tabulator, these links allow you to navigate from the description of the author of a book to his papers in the DBLP database. The links are generated by asking the SPARQL-endpoint of the DBLP database for URIs identifying book authors. If the query for a foaf:person with a specific name returns only one result and as both domains are related, we assume that it is likely enough that we have hit the right person, to set the owl:sameAs link. An example of such an auto-generated owl:sameAs link is found in the data about Tim Berners-Lee: http://www4.wiwiss.fu-berlin.de/bookmashup/persons/Tim+Berners-Lee <foaf:Person rdf:about="http://www4.wiwiss.fu-berlin.de/bookmashup/persons/Tim+Berners-Le e"> <owl:sameAs rdf:resource="http://www4.wiwiss.fu-berlin.de/dblp/resource/person/100007"/> <foaf:name>Tim Berners-Lee</foaf:name> </foaf:Person> Cheers, Chris [1] http://sites.wiwiss.fu-berlin.de/suhl/bizer/bookmashup/index.html -- Chris Bizer Freie Universität Berlin Phone: +49 30 838 54057 Mail: chris@bizer.de Web: www.bizer.de
