    • Transformation “Triplication”Do you think people fromthe city understand allthe technical jargon?
    • Creating Linked Open Data•  Getting the data•  Modeling your data – schema•  Transforming your data•  Create applications
    • Data Sources•  Local government data Biel/Bienne website - 1 star data•  Marketing, Sports, Events, etc.•  Most of data not open or in PDF•  Swiss statistics – 4 stars data•  Open data in excel•  Moving to 5 stars•  Web data –five stars data•  Open street maps•  Wikipedia•  295 open datasets in 2011
    • Transforming your dataFree and open source tools:•  LOD2 stack•  D2R[Q]•  LIMES•  …•  Biel/Bienne use case : LODGRefine•  Extension of Google Refine for LOD•  Import data from cvs, xls•  Clean/Refine your data•  Associate data with chosen vocabularies•  Link your data with other open datasets•  Export to RDF
    • Triplication ProcessVocabulary(Ontology,schema)Refine,Clean,LinkInsert,ExposeRDFSPARQLEndpointTools:OpenRefineRDF Refine (DERI)Google Refine (old)Publish the Data CatalogueWe use “OntoQUAD”(…there are manyRDF graph databases)
    • Ontology Model based on schema.org
    • Clean data and link to ontologyhttp://openrefine.org/http://refine.deri.ie/LOD2 stackZRH, Zürich, Zuerich, Zurich
    • LODGRefine
    • Summary Iq Collect data from Web and store in XLS (CSV)q Model Ontologyq Clean data using OpenRefine / LODRefineq Connect CSV colons to RDF(ontology)and Reconcile (link to other data) “5 star”q Export the RDFq Load RDF to Graph database (OntoQUAD)and publish the data as SPARQL endpointand/or on a datacatalogue
    • Orchestration of Linked (O) DataUsing as many as possible Open Source Tools-  From the LOD2 stack (LIMES) “EU FP7 project”-  D2RQ from FU Berlin and DERI (and others)-  NLP engines-  RDF Store (OntoQUAD, Virtuoso, etc)OntoQUAD – BSBM May 2013
    • Proof of Concept “Demonstrator”Biel/Bienne demo of what can be achievedwith open linked data http://citydemo.ontos.com/#•  Which is the best neighborhood to live If I want tohave:•  A Child care center•  Bilingual school•  Handicapped parking for visiting friends …•  How much are the housing prices compared withMorges?
