Open Data is more usefull when ist
Creating Know l e dge
out of Interlinked Data
                              linked!!!
 Problem: Try to search for these things on the current Web:
 •   Apartments near German-Russian bilingual childcare in Berlin.
 •   ERP service providers with offices in Vienna and London.
 •   Researchers working on multimedia topics in Eastern Europe.
 Information is available on the Web, but opaque to current search.

 Solution: complement text on Web pages with structured linked
 open data & intelligently combine/integrate such structured
 information from different sources:
                                     HTML
                                                    Search engine                   HTML
                                                                              RDF
                                            RDF
                                    Web                                                Web
        data.berlin.de             server                  Immobilienscout.de         server
        Has everything about                               Knows all about real estate
        childcare in Berlin.        DB                     offers in Germany           DB

      TimBL’s 5-star plan for open data
                                              ★ Make your data available on the                            Web
                                             under an open license

                                                     data
                                                          (Excel sheet instead of image scan of a table)

                                          ★★★ Use a non-proprietary format
                                                          (CSV file instead of an Excel sheet)

                                       ★★★★ Use Linked Data format
                                                          (URIs to identify things, RDF to represent data)

                                       ★★★★★ Link your data to other
                                                   people’s data to provide
